Help! How Do I Save My Anthurium?

Ask The Plant Expert: I got a baby anthurium as a Christmas gift, and I have been watering about 300ml of water every second day. Most of the leaves have like brown, dead patches on them, and the flowers are turning brown slowly as well. What do I do?? Please help.

Flower Shop Network Plant Expert Reply: Anthuriums are a tropical plant originating in Central and South America. That means they need a lot of water and humidity. It is a good idea to mist your anthurium every day and keep watering every other day. You can also keep your anthurium on a tray of pebbles with water to increase moisture and humidity.

  • The Water Test

The best rule of thumb is to do the soil squeeze test. Stick your finger down in the soil up to your first joint. Pull a small amount of soil out. If you can roll the soil into a ball and squeeze out water or if the ball stays together, you don’t need to give the plant anymore water. If you can’t roll the soil into a ball and it is powdery, give it some water.

The plant will tend to need more water during the spring and summer even if kept inside. During the fall and winter, you can reduce your watering depending on your specific environmental conditions.

  • Sunlight

Sunlight could also be a factor for the browning of your anthurium. While, they do enjoy long sunny days, they prefer it to be filtered. Do not put your anthurium in direct sunlight. If you are unable to give your plant filtered sunlight, you can use artificial light. It’s best to give your anthurium at least 9 hours of light a day.

What is causing the leaves on my anthurium to turn brown?

Anthuriums are popular, and rather easy plants to grow, even in our cool, dark Minnesota homes. I’m not sure how long you’ve had this plant but it may be ready for a re-potting, using fresh potting soil and a larger, clean pot. They aren’t heavy feeders so a new soil mix with a timed release fertilizer may be a good choice.
The browning leaves suggest that this plant may not be getting enough moisture. It may be that the root ball has become too compacted and dry – causing the melting water to run around – rather than through the roots.
If you do want to repot, soak the plant first, knock it out of the pot, shake off the old soil and then gently tease out the white roots. Anything that has blackened, or withered badly should be cut out.
Rather than using ice cubes, you can consider thoroughly soaking the plant, and then allowing all of the water to drain out. Do not re-water until the soil gets pretty dry. This is a good way to water plants that prefer a drier soil because the root ball tends to dry out too much, and shed water.
As daylight becomes stronger, and longer, and the temp.s warm up, I think this plant will do just fine. You may chose to trim out the leaves that have browned – sometimes this encourages new growth, and this is just the time of year for that to happen.
Good luck, and contact AaE again if you have further questions.

Ask a Question forum: Help with my anthurium: brown spots, one leaf turning yellow, one flower left

Hi,
I purchased a healthy anthurium early november last year and placed it on a west-facing window-sill, away from direct sunlight.
A few weeks later I fertilised using a N8-P1-K5 fertiliser, as recommended by the nursery. And a few days later, I noticed some brown spots on some leaves, mainly those close to the window.
I first assumed it must be too cold for the plant there and moved it away from it.
As time went on, more brown spots appeared. And some flower started to turn brown too.
A few weeks ago, I cut off the brown leaves and flowers using clean scissors and water only when the soil was dry. Sprayed the plant too, around twice a week as the air is rather dry in our flat.
Today, after I noticed more brown spots, I cut of some more leaves. And did some research, which led me to “flush” the plant and leave it to drain onto absorbent paper.
I also noticed a leaf turning yellow at its base, a first here!
I’m attaching some pictures of the plant below, right after the flush.
Any help and advice would be greatly appreciated as I’m very new to this plant and would love to save it!

With glossy green leaves and rich red blooms, Anthurium is one of the most stunning plants to grow indoors. Also known as flamingo flower or painter’s palette, it will add a touch of luxury to an indoor space. Thankfully, anthuriums aren’t hard to care for and will thrive indoors when provided the right conditions. Before I go into detail, here’s a quick summary of its care.

How to care for an anthurium plant: Anthuriums should be planted in well-draining, acidic soil, and kept in humid conditions at temperatures of 60 °F to 90 °F. Water infrequently but thoroughly once the top inch of soil is dry, and fertilize every other month through the growing season.

Flamingo flowers will survive by following the simple advice above. But if you really want to let your anthurium thrive, read on and I’ll tell you how to get the most out of this beautiful plant.

How Do You Water An Anthurium?

Allow the top inch of soil to dry before watering an anthurium. Stick your finger into the potting mix about an inch and if it feels dry irrigate. Always water thoroughly until the water runs from the bottom drain holes.

During the growing season of March through September, you can expect to water about once weekly. This gives the soil time to dry out before watering again.

However, during winter when the plant goes into dormancy (growth slows), the anthurium will probably only require water about once every two weeks. The frequency you will need to water will depend on the individual conditions that you are growing your plant in, but you should get an idea of the pattern before too long.

Don’t overwater or allow the pot to sit in standing water, as root rot can develop which can lead to the anthurium’s death. On the other hand, don’t allow the soil to completely dry out, which can also lead to problems with the plant’s growth and health.

Does An Anthurium Need Humid Conditions?

Native to the warm and humid tropical regions of Ecuador and Colombia and considered a tropical perennial evergreen in its natural habitat, anthuriums grow as an epiphyte, using the jungle trees as support.

Therefore, it is only natural that anthuriums require a humid environment indoors for proper growth. Maintaining a humidity level of around 80 percent is preferred.

You can easily create humidity for the plant by misting it with room temperature water every couple of days. Others options include using a humidifier or humidity tray. As I have quite a lot of houseplants, I bought a humidifier, which makes it so easy to maintain good humidity levels for my plants with minimal effort.

To help maintain the much-needed humidity, don’t place your anthurium close to a heating system or vent that produces hot, dry air.

What Indoor Temperatures Are Best For Growing An Anthurium?

Being a tropical plant, anthuriums grow best when indoor temperatures aren’t too cold or too hot and maintained in the range of 60°F to 90°F (15°C to 32°C). However, anthuriums grow best when indoor temperatures at night are kept around 68°F (20°C) and around 86°F (30°C) during the day.

If you want to give your anthurium a break outdoors when the weather warms in spring, be sure to bring it back indoors when nighttime temperatures start dipping below 50°F (10°C) so it doesn’t suffer damage.

How Much Light Does An Indoor Anthurium Require?

Indoors, anthuriums thrive when placed in a location that receives medium to bright indirect light. However, during winter while the plant is dormant, they will tolerate receiving less light. Don’t place the anthurium in an indoor location that receive bright, direct light especially during the afternoon or the foliage can burn.

It is good to remember that in their native environment anthuriums grow beneath tree canopies and are protected from the direct rays of the sun.

What Are Some Problems With Anthuriums Grown In Improper Lighting?

In addition to foliage burning when light conditions are too bright, when light conditions are less than ideal the foliage can also lose color turning paler.

This can lead to you thinking it’s suffering a deficiency in nutrients and requires additional fertilizer, though it only requires more light. If light conditions are too low, the anthurium ceases producing flowers.

Anthurium Flowers

Although anthuriums’ shiny green, heart-shaped, tropical foliage is attractive on its own and adds a blast of greenery to the home, the stars of the show are the plant’s waxy, heart-shaped bracts or spathes, born on long stems and blooming in a variety of colors.

The spectacular bracts are actually modified leaves, rather than being the flowers of the plant. The true flowers are the tiny bumps that grow along the finger-like projection, called the spadix, which rise up from the spathe.

The tiny flowers are just about the longest lasting flowers you can grow at home. What this means is that the spectacular elegance of the colored bracts remain for months at a time if cared for correctly.

Do Anthuriums Flower Every Year?

Anthurium flowers can last for more than three months and will produce new blooms all year round if given adequate light and care. Anthurium plants can live for years, and bloom again and again. They will produce fewer flowers in winter or if grown in a lower light location.

How Do I Get My Anthurium To Bloom?

The best thing you can do for your anthurium to promote blooming is making sure you are meeting its basic needs for healthy growth indoors. This includes:

  • Growing the anthurium in fertile soil that drains well.
  • Using a container that has bottom drainage.
  • Watering when the top inch of soil is dry to the touch.
  • Ensure your anthurium is getting sufficient humidity.
  • Fertilizing every other month with a houseplant fertilizer high in phosphorus and applying at half strength.
  • Placing the anthurium in an area that receives bright to medium levels of indirect light during the day.

Your anthurium is less likely to produce flowers if it isn’t happy with the conditions it is living in. Also very important to the production of flowers is making sure the plant is receiving enough light. If lighting conditions are too low, the anthurium won’t produce blooms.

My Anthurium Isn’t Producing Many Blooms

If your anthurium is happy with its growing conditions, is a mature plant that is blooming but just not producing an abundance of flowers, there’s probably nothing wrong with it and it’s flowering at a normal level of production for anthuriums.

Understanding anthurium blooming habits will alleviate any unnecessary worries you might have that something is wrong with your plant. Mature anthuriums produce larger flowers and bloom more often throughout the year than immature plants.

Even the best cared for anthurium plant produces an average of about six flowers each blooming cycle, so don’t expect your plant to be covered in blooms. The great thing about the blooms is they are long-lasting, staying colorful and perky for about 6-12 weeks. Even as cut flowers, anthurium blooms last about six weeks.

Does An Anthurium Require Fertilizer?

To keep your anthurium happy, healthy and to promote flowering, fertilize it every two months. Use a water-soluble blend with a high middle number, which is the amount of phosphorus the product contains that promotes blooming.

You can apply the fertilizer when you water by using a half-strength blend and watering until it runs from the bottom drain holes.

Fertilize while the anthurium is actively growing during spring and throughout September. Cease fertilizing in fall and winter, as the plant is in its dormant stage where all growth naturally slows.

Do I Need To Flush The Soil To Remove Fertilizer Salt Build-Up?

Although anthuriums aren’t heavy feeders when compared to many potted plants, the soluble salts in fertilizers can still build-up in the potting mix causing foliage burning. It’s a good practice to flush the soil every couple of months to remove salt build-up.

This process is as easy as taking the pot to your sink and allowing water to run slowly over the soil and out the bottom drain holes for several minutes. Doing this on a regular basis assures any build-up of salts from the fertilizer is flushed from the soil.

What Soil Does An Anthurium Need?

Anthuriums grow best in coarse, well-drained, fertile soils with a pH of 5.5 to 6.5.

You can make your own soil mixture by using equal parts of peat, perlite and pine bark and mixing them together. If you don’t want to make your own mixture, using a commercial potting mix or orchid mix also works well, but don’t use a potting soil because it’s generally too heavy and retains too much moisture leading to rot problems.

It’s helpful knowing that in their native habitat anthuriums grow on tree branches in a mixture of moss and leaf litter, which is a breathable soil blend.

How Often Should I Repot An Anthurium?

Anthuriums only require repotting about every two to three years when it has outgrown its pot. It’s quite easy to tell if it’s time to repot because the root system starts growing out of the pot’s bottom drain holes or wrapping in a circular direction.

How Do I Repot My Anthurium?

If your anthurium is showing signs of outgrowing its current container, it’s time to do some repotting. Select a container that is slightly larger than the one the anthurium is presently growing in, as using a container that is too large, can mean the soil stays too wet, which can lead to rot problems.

Make sure the new container has bottom drain holes and fill it about a quarter full of the potting mix. Gently remove the anthurium from its current pot, snipping off the roots growing out of the drain holes, if needed, so it pulls from the container without force, which can cause damage to the plant and the fragile root system.

Place the anthurium in the new pot and cover with fresh potting mix, being sure not to plant any deeper than it was originally growing. Firm the soil up around the plant’s base using your fingers and water well. Situate the new container back where the plant was originally growing.

What Type Of Container Should I Use For My Anthurium?

Unless the anthurium you purchase is showing signs of growing out of its nursery pot, it should grow happily in the present container for another couple of years. However, if you want to repot into a more decorative container or it’s time for repotting, the biggest need in a new container is making sure it has bottom drainage to prevent rot.

Any type of material works well for growing potted anthuriums from plastic to terra cotta, however, those grown in clay materials like terra cotta might need more frequent water applications, as the soil dries quicker than it does in plastic pots.

If the anthurium hasn’t outgrown its present container, repot into one that is the same size. If the plant has outgrown its present pot, repot into one that is only slightly larger. Using a too large container can lead to the soil remaining too wet, which can lead to plant problems like rot.

I double pot most of my indoor houseplants, and this works well for anthuriums. Choose a really well draining inner pot and place it into a decorative outer pot which has no drainage holes. This negates the need for a drip tray and adds to the beauty of your houseplant. It gives you so much freedom to choose a decorative pot to your liking.

Do Anthuriums Need Pruning?

The only pruning anthuriums require is to trim off spent flowers and to remove dead or damaged foliage. When pruning, always use clean pruning tools so you don’t transfer any diseases to your anthurium. This is as easy as wiping off the blades with alcohol.

Anthurium Propagation

Propagating new anthurium plants is easily done by dividing a mature plant in spring. Carefully and gently separate the root mass into multiple sections and plant as usual. Make sure each section has at least one leaf and healthy roots.

How Big Do Anthuriums Grow?

Depending on the particular cultivar (variety) and when grown in preferred conditions, anthuriums grow anywhere from 2 to 3 feet tall and wide at maturity.

Anthuriums are considered to have a relatively slow rate of growth and can take a year or more to achieve their mature size.

Do Anthuriums Produce Fruit?

If the spadix in the center of the anthurium flower is pollinated, it eventually develops small clusters of red berry-like fruits.

Will An Anthurium Grow In My Bathroom?

Provided you bathroom gets adequate light, an anthurium grows quite well in a bathroom due to the levels of humidity.

How Long Do Anthuriums Live?

If you properly care for your indoor anthurium, you should be able to enjoy its tropical lushness and exotic flowers for many years.

What Color Are Anthurium Flowers?

Once upon a time, you mainly saw anthuriums (flamingo flower) in shades of red, but you can now find varieties producing pink, white and salmon flowers.

Are Anthuriums Poisonous To People And Pets?

Anthuriums contain calcium oxylate crystals, which are toxic to people, cats and dogs, so keep your plant out of the reach of curious pets and children. Ingesting the substance causes irritation to the mucus membranes and G.I. tract.

Why Isn’t My Anthurium Growing?

Unless it’s winter, when anthuriums go into dormancy and stop growing until weather warms in spring, the problem with an otherwise healthy looking anthurium not putting on proper growth is more than likely due to the plant not being happy with some of its growing conditions.

The number one reason might be it’s not getting enough light. Anthuriums grow best situated in an indoor location receiving bright to medium levels of light. You can also make sure it’s getting enough nutrition by fertilizing with a water-soluble, houseplant blend applied at a half-strength every two months.

Why Do Anthurium Leaves Turn Yellow?

If your anthurium’s leaves begin yellowing, which eventually encompasses the entire leaf, you might be overwatering. Stick your finger into the soil and if it’s wet and soggy feeling, wait until the top inch becomes dry before watering again.

When it comes to anthuriums, it’s better to underwater than use too much too frequently. Only water when the top inch of potting mix feels dry to the touch and then apply until it runs from the pot’s bottom drain holes.

Why Are My Anthurium Leaves Turning Brown?

If the tips of your anthurium’s leaves are turning brown and the condition seems to grow, more than likely you are keeping the soil too dry. Stick your finger into the soil and if it’s dry apply water until it runs from the container’s bottom drain holes.

Fix the problem by watering your anthurium on an appropriate schedule of applying water when the top inch of soil feels dry. This will more than likely mean you will need to water about once weekly during the growing season, and about every other week during winter.

Since the brown will remain on the affected leaves even after you’ve corrected the irrigation problem, you can trim off the browned sections with clean pruning snips.

Why Are My Anthurium Leaves Losing Their Shine?

If your anthurium’s foliage starts losing its glossy shine and changes to a dull, flat green, the plant isn’t receiving enough humidity. Remember, in their natural habitat, anthuriums are jungle plants living in a humid environment.

You can easily correct the problem by increasing the humidity around the plant by misting it with water several times each week, or sitting the pot on a tray of pebbles that hold the water running out of the bottom drain holes.

Why Have Some Of My Anthurium’s Leaves Lost Their Color In The Center And Have Brown Tips?

If your anthurium’s leaves start having bleached centers along with brown leaf tips, this is usually a problem of the light conditions being too bright.

Numerous dry brown patches on the leaves are often a sign of sunburn. When checking its location you will probably find it’s receiving direct light instead of bright, indirect light.

Although anthuriums tolerate and bloom best in bright, indirect light, foliage damage occurs when plants are situated in a location receiving direct sun. Alleviate the problems by moving the anthurium to an area that doesn’t get as much light. L

Over-Fertilizing Anthuriums

Sometimes the bottom leaves of your anthurium will develop brown tips and lose their deep green color. If you know it’s getting adequate light and you aren’t overwatering, your plant might be suffering from too much fertilizer.

As you can probably guess, you need to cut back on the amount and frequency of fertilizer applications. Your anthurium will thrive with every other month applications of a water-soluble houseplant fertilizer applied at half-strength.

The best course of action for your affected anthurium is to take the container to the sink and slowly flush the soil with water, removing any salt buildup. Let the water run gently through the soil for about five minutes and then carefully remove the anthurium from the pot and inspect the roots for damage. Carefully snip off any damaged or dead sections with clean pruning tools and replant the anthurium back in the pot.

Anthurium Root Rot

If you notice areas around the base of your anthurium turning black and getting mushy, this should raise alarm bells as it’s often a sign of root rot. You may also notice the older foliage losing its rich green color, turning more yellow, and the entire plant may be wilting.

If large areas of the plant are quickly developing black rot, you more than likely can’t save the anthurium, but if only a small section is affected, you can take quick steps to salvage a portion of the plant.

Gently remove the anthurium from its container, shaking off excess soil, and inspect the roots for rot. Trim off the infected section with sterilized pruning tools.

Wash the container with soapy water before refilling it with a clean, well-drained potting mix and replant the anthurium at the same depth it was originally growing. Repotting in a soil that is too heavy and doesn’t drain well will only lead to the problem reoccurring.

Hold off watering the newly potted anthurium for several days and then resume watering when only the top inch of soil feels dry to the touch.

Anthurium Pests & Diseases

It is easy to identify if you have a problem with spider mites on your anthurium. When you gently shake the plant if you see tiny, white flying insects hovering around the anthurium, you have got yourself a spider mite problem. Spider mites are common to indoor anthuriums grown in too wet conditions.

Cut back on watering, irrigating only when the top inch of soil becomes dry, to assist the soil in becoming dryer. Spider mites are sap-suckers and can quickly damage your anthurium and also travel to your other indoor plants, so you need to treat the problem quickly.

Using an insecticidal soap, saturate all areas of the plant, reapplying weekly or as recommended on the product label.

Aphids

Aphids are another sap-sucking insect that can infect anthuriums grown in too wet conditions. The tiny, pear-shaped insects come in a host of different colors and cling in mass groups along the underside of the leaves and along the fresh, new stems. They too can infest your other indoor plants if the problem isn’t treated.

Treat the aphids with an insecticidal soap, saturating all areas of the anthurium, including the underside of the leaves and reapplying weekly or as recommended on the product label.

You can also try wiping them off with a damp cloth dipped in water. Only water your anthurium when the top inch of soil becomes dry.

Mealybugs

Mealybugs are another sap-sucking pest that are easy to identify and are common pests in excessively wet conditions indoors. The insects form into cottony masses along the leaves and fresh, new growth. Like spider mites and aphids, mealybugs can also infest your other indoor plants if they aren’t treated.

Use an insecticidal soap to saturate all areas of the anthurium, and reapply weekly or as recommended on the product label. Reduce watering to only when the top inch of soil becomes dry.

Bacterial Blight

You have a problem with bacterial blight if you notice your anthurium’s leaves developing yellowish, water-soaked lesions that quickly turn to brownish-black and die. The blight is most problematic when humidity is high and nighttime temperatures are high.

It is essential to prune the affected foliage from the plant with sterilized pruning tools. You can control further outbreaks by lowering the humidity levels and indoor temperature, as well as making sure there is good air circulation around the anthurium and applying water only to the soil, keeping it off the foliage.

Bacterial Wilt

If you notice the leaf veins on your anthurium yellowing and then the entire leaf changes to a brownish-bronze color and although the plant is receiving enough water it’s wilting, you have a problem with bacterial wilt.

Using unsanitary tools, containers and soil is the usual cause of this problem and when indoor conditions are cool, the anthurium might not show signs of the bacterial wilt until conditions warm.

The best course of preventing this problem is making sure you only use fresh, clean soil when repotting, as well as clean containers and sterilized tools. Keep the area around the plant clean by removing any dead and dropped foliage or debris.

Anthurium with Browning Leaves

Question:

I bought an Anthurium with red flowers from the local supermarket last March and it’s been sitting in a well lit office ever since. It’s not near a window or near natural light. It hasn’t had flowers since about June/July. Over the past month or two, it’s been getting brown dried tips on the leaves. It’s potted in two pots, one with holes on the bottom and another that holds the cheaper one with the holes. I water the plant about once a week with a cup of ice cubes, per the instructions that came with it. Before the browning on the leaves started, the plant grew an abnormal flower and hasn’t had any flowering since. I looked at the roots and checked to see if the soil was wet at the bottom and it didn’t seem wet or soggy. I haven’t repotted the plant or fertilized and it’s in a 6-8 inch pot. Thanks in advance.

Answer:

Most flowering plants sold today are hybrids that have been bred to bloom profusely at point-of-sale. Unfortunately, the downside of that hybridizing is that those flowering plants bloom sporadically and somewhat weakly thereafter. That leads to a lot of frustration. You cannot alter the genetic makeup of your Anthurium, but there are some things you can do to get the best out of what you have.

Office fluorescent lighting is very good for green foliage, but not so good for flower production. Anthuriums are more likely to flower if they get lots of bright indirect natural light, such as you get on a north windowsill. If you are happy to keep it as a foliage plant, then leave it where it is.

Using ice cubes to water plants is an out-of-date, discredited horticultural practice. Most houseplants are tropical in origin and do not like anything very cold. It is also very difficult to control the volume of water when using this method.

A better way to water your Anthurium is to take the inner pot to the sink and allow lots of water to run through and out of the drain holes. After it has finished draining, put it back into its outer pot. Once a week is about right, but the top half inch of potting mix should feel dry before you water. You can add some fertilizer diluted to half strength every month or two.

Your Anthurium will be very happy in that pot for as long as yo have it, so don’t even think about repotting it.

I only see one leaf that has some edge yellowing and a couple of leaves with brown tipping. A certain amount of yellowing and tipping is normal. You will also lose a few older leaves as the plant ages. If these symptoms become excessive, it is usually because it is not getting enough light or the watering is not quite on target. Leaf discoloration of edges and tips can be trimmed off with sharp scissors just to make it look a little more attractive.

There is probably no such lover indoor plantswho would not want to buy anthurium, which is by no means cheap. But even having bought beautiful flower, not everyone will save it, because of the inability to maintain all the necessary conditions. The popular name of Anthurium is male happiness, it is traditionally given to men, because it is believed that the plant brings good luck to the stronger sex. Many diseases of anthurium at home are associated with non-compliance with the rules for caring for it. Knowing how to care for an anthurium flower, diseases can be prevented. The capricious native of the tropics requires maintenance at a temperature of at least +20 degrees and good lighting, while the sun’s rays should not fall directly on the flower. The plant feels good at high humidity, therefore, it must be sprayed daily (in warm time, even 2 times a day). Watering is required moderate, while keeping the soil under control so that it is slightly moist.

As noted above, mainly diseases of male happiness – anthurium are associated with improper care.

Leaves dry and yellow

Diseases when the leaves dry in anthurium can be associated with two factors.

  1. Damage to the greenhouse aphid. The leaves of the anthurium become shriveled and become covered with yellow spots, while flowers are falling. To destroy the pest, the plant is treated with a solution of feverfew or tobacco infusion. You can use the drugs “Actellik” and “Karbofos.”
  2. Lack of lighting or sunburn. Lighting should be adjusted: place the flower in a well-lit place, but avoid direct sunlight.

Stains appear on the leaves

The appearance of dark spots and dots indicates that the anthurium is suffering from low temperature. It is necessary to put the plant in a warm place and reduce watering.

Another cause of anthurium leaf disease is a lesion that settles on the aerial parts. Cracks appear on the shoots, and spots appear on the leaves; subsequently, the leaves may fall off. The plant to get rid of the pest is treated with “Karbofos”.

The tips of the leaves turn black

Sometimes the leaves of the anthurium blacken at the ends. This occurs as a result of an excess of calcium salts in the soil; in this regard, a flower should be transplanted into the soil with a more suitable composition.

The appearance of dark spots on peduncles

One of the diseases of indoor flowers, anthurium is characterized by the formation of spots on the prowl of the peduncle. Although the plant loves when it is sprayed with water, it does not tolerate when drops fall on the inflorescences. Affected flowers must be removed, and in the future, such a breach in care should not be allowed.

Fungal diseases

Often, anthurium flower diseases are associated with the negative effects of fungi.

Defeat avocado scale

If a scab has settled on the underside of the leaves, then the leaves become unpleasantly sticky. To get rid of the pest, you need to wipe the leaves with a cloth soaped with laundry soap. You can also treat the plant with 2% Karbofos.

The handsome anthurium is considered moody, but thanks to the stunning flowering and chic greens, it is grown even by novice florists. The care is complicated, sometimes even experienced professionals make a mistake, which is detrimental to a tropical guest. Most often, greenery suffers – ugly spots appear on it, or, even worse – drying of the aboveground part begins. How to determine the cause of the problem, how to help your pet and prevent repeated trouble?

Yellow leaves

There are many difficulties waiting for florists who have just begun their uncertain steps in a difficult hobby. A native of heat-loving countries is no exception, because only yesterday a healthy bush in the morning can become covered with ugly spots. Professional advice will come to the aid of beginners who are interested in how to treat various diseases of Anthurium and will help to correctly determine the nature of the problem from the photo.

The most common surprise manifested on greenery is yellowness. Why does this happen? This can happen for several reasons. The most important thing is the wrong actions of the owner, who overdid it with water procedures. Abundant and frequent watering does not have time to be absorbed, an excess of moisture appears, which is unacceptable in growing a native of the tropics.

The problem begins with the decay of the root system. Rot spreads to the stem, then the leaf plates are covered with yellowness and gradually die off. It is difficult to save the bush, especially if the moment the appearance of leaf disease in Anthurium was missed. The only thing that will save the magnificent guest is timely removal from the pot, drying the root system and processing with chopped charcoal.

The presence of chlorine in water can cause a similar problem. You can prevent yellowing only by settling the liquid for 7-10 hours. If there is a filter, you can purify the water with a useful device.

The flowerpot in which luxurious anthurium grows often does not match the size of the roots. Cramping can also cause yellowing, and this will occur slowly. If you don’t urgently move the pet into a larger pot, yellowness will hit all the leaves, in this case it is very difficult to save the guest from the tropics.

The last mistake leading to the yellowing of the thermophilic guest is the excessive efforts of the hosts in introducing nutrients. Excess fertilizer will quickly change the shade of leaf blades. The process is irreversible – the affected fragments will only have to be removed. Stopping the infection is easy. Prepare a working solution to fertilize the bush with a weaker one: use half of the amount specified by the manufacturer.

Dry edges

With dry brown spots, the flower of male happiness is covered often, especially if the moisture of the substrate does not occur regularly. Dry earthen lump in a container with a plant is the cause of the disease. There are several ways to get rid of the problem:

  • moisturize as the surface dries;
  • water in a pan, draining water only after saturation of the substrate with moisture;
  • spray the entire surface regularly.

The cause of dry leaves may be anthracnose. It is not difficult to recognize the disease – delicate greens begin to dry along the edges, after a while, if the necessary treatment is not carried out, brown spots on the leaves pass to healthy tissue. Treatment of the disease is carried out by several sprayings of fungicides. The working solution is prepared strictly according to the instructions.

Brown leaves or spots

The brown color of the leaves of male happiness is a frequent phenomenon. Trouble can happen through the fault of the owners – the wrong substrate affected the natural shade. It’s easy to fix the mistake – to purchase a ready-made soil mixture designed specifically for this type of indoor plants.

Important! Transplant carefully, being careful not to harm the root system. A trauma to the root will not allow you to get rid of the brown color, and a native of warm edges will be a long time unnatural shade, until it takes root in a new substrate.

Brown greens can also become due to improper temperature conditions. Subcooling of soil in a pot is especially harmful. The mistake of the owners is the content of anthurium on a cold windowsill. It is not difficult to avoid the disease – put a thin sheet of polystyrene under the pot – the insulating material will not allow the root system to cool.

Hard water can also affect the color of the aerial part of the bush. Longer boiling and settling will help make the liquid softer. The process is laborious, but before growing behind anthurium, you should prepare for considerable difficulties, including watering.

Diseases and pests can spoil the shade of the leaves of anthurium. The brown color of the aerial part of the bush may appear from infection by the ubiquitous aphid. An insect can get into the house in many ways:

  • through an open window unprotected by a grid;
  • with an acquired plant;
  • on a bouquet of flowers;
  • in untreated substrate before planting.

If there are few harmful insects, you can destroy them with home remedies. Effectively proved themselves in the fight against pests that occupied male happiness, decoctions of tobacco crumbs or bitter wormwood. The solution can be prepared concentrated – spraying will not bring harm to the plant.

A large number of harmful insects can not be destroyed by folk methods, you need to resort to chemicals. Usually it is Actellik, which in just one treatment will completely clean the plant from insects.

Blackening

The appeared black shade should alert the hosts, as it is a sign of a dangerous anthurium disease. One of the main reasons is the wrong temperature in the room (too cold or too hot). The only way to fix the mistake is to put your handsome man near the heater or away from the heat source. Usually this is enough to return a natural green tint in a few weeks.

Often, blackness on the aerial part appears from strong regular drafts. To stop the trouble and help male happiness, you can rearrange the container on a more comfortable window sill. If this is not possible, then before each airing of the room, remove the bush away and return to the place only after the window has been closed.

Direct rays of the sun can cause irreparable harm to the pet in the form of black spots. If you do not react in time and remove the container from the destructive window sill, the magnificent “lodger” will die, and quite quickly. During the hottest hours, you can use a light curtain or a regular newspaper to create a shadow and protect your pet from fatal ultraviolet radiation.

Excess calcium in the soil is also fatal. Evidence of the disease is blackened leaves and white plaque on the walls of the tank and the surface of the soil. Correct the situation by removing part of the substrate. For the next transplant, we recommend that you carefully select the soil for the handsome man, because calcium salts accumulate only in heavy clay soil.

Attention! Septoria is a disease, the infection of which also leads to blackening of the aerial part. There is no cure – only the complete removal of infected leaves will save the entire magnificent specimen. If you delay and do not help, you can destroy the flower, it will not be possible to reanimate it.

Anthurium disease usually occurs due to inattention of the owners or with too zealous care. A lot of attention can also result unpredictably – a healthy plant quickly withers and dies. Diseases can only be avoided in one way – to adhere to the basic rules for caring for the capricious “lodger” and, if possible, immediately correct the mistakes made.

They gave you an anthurium, but it didn’t delight you for long with its beauty? If its appearance begins to deteriorate, the flower fades or rots, you do not need to wait long. Save the anthurium. Disease will turn it into a dry bush. And from the past splendor there will be no trace.

What is remarkable about anthurium?

Among other indoor plants, it stands out with a special decorative effect. It has large smooth leaves of a saturated green color, heart-shaped. They grow a lush bush, and by themselves look beautiful. But when large bright flowers, it’s simply impossible to look away from them.

Flowers come in many different shades:

  • from pink to red;
  • from milky to coral;
  • from peach to deep burgundy;
  • from light green to yellow;
  • several tones at the same time (bicolor, tricolor).

What varieties are most susceptible to disease?

Varieties differ in the size of inflorescences and leaves, but common to them is the presence of a long slightly curved cob. For its bizarre appearance, the plant received the name “Flamingo Flower”. It is especially suitable for Scherzer’s pink anthurium. Among flower growers, the most popular is the Andre variety of different colors. There is an opinion that a bright and peculiar flower pleases women and brings good luck to men, therefore it is also called ” male happiness”. Often men are presented with a large red Dakota Anthurium. Diseases, unfortunately, affect all varieties under the wrong conditions.

Anthurium diseases and their treatment

For good growth and flowering, the plant must provide the conditions of the native tropical climate of South America. A well-lit, warm place with moderate humidity will suit him. If your pet does not bloom for a long time, has stopped or has slowed down significantly in growth, its leaves become smaller and do not shine, you need to pay more attention to it. Move the pot to a more lighted window sill, pick up fertilizer and add it to the water for irrigation at least once a month. Try to get your anthurium care, then he will not be afraid of illness. It will bloom and delight you with its splendor.

But if you notice that the leaves began to turn yellow or become covered with strange spots of brown, rust, brown or black, then your anthurium was affected. Leaves mostly suffer, although in the case of a fungus or pest affection, the disease can spread to the bract. Carefully inspect the surface of the leaves, maybe aphids or scale insects settled on them.

Possible pests and methods of controlling them

Diseases and pests attack the anthurium if the air in the apartment is too dry or, on the contrary, too humid. When inspecting, pay attention to the cuttings and the root zone, as well as the inner surface of the leaves.

There are contagious diseases of flowers. Anthurium, for example, may be infected with fusarium. Symptoms are as follows:

  • depressed appearance;
  • yellowing and wilting of foliage;
  • abnormal bending of peduncles and stems;
  • dark areas at the base of the shoots with a whitish bloom.

If during transplantation you have not processed the substrate, harmful spores may remain in it. The soil is better steamed or calcined. If fusarium is suspected, treat the soil with glyocladine or another suitable fungicide.

Septoria

The causative agent is Septoria mushroom. It spreads in a moist and warm environment, quickly affecting the entire anthurium. Leaf diseases cannot be avoided unless the rotted parts of the plant are carefully removed. They can be distinguished by specific spots. At first they have a brown color, then their center becomes lighter. A yellow rim appears around the spot. After a while, the diseased leaf withers. Mushroom spores easily penetrate the soil, and also fall on healthy parts of the leaves with drops of water. Therefore, spraying a diseased plant is undesirable. They are treated with preparations containing copper (cuprocin). Fungicides are also suitable.

Anthracnose

This is another dangerous disease caused by Colletorichum mushrooms. What are the signs of anthurium-afflicting disease? The leaves, petioles and stems dry, the whole plant is quickly affected by spores and can die within a month. Most of the flower can be saved if treatment is started after the onset of the first symptoms. First, brown spots appear, on which dark spores are visible nearby. Over time, small patchy areas increase, turning into a solid dry area. Especially violently passes the course of anthracosis in a greenhouse atmosphere, that is, with increased humidity and heat. The danger is that the fungus spreads to healthy areas with water when watering and spraying.

If anthurium has been affected, treatment should choose the following:

  • to reduce watering or not to water at all for 1-2 weeks;
  • add special agents to the water for spraying (solution copper oxychloride or copper sulfate 100 g per 2 liters of water);
  • trim all leaves with brown spots;
  • if necessary, soil should be treated with disinfectants (Abiga-Peak at 5 g per 1 liter);
  • with a serious damage to the flower and inconclusive treatment, it must be burned, since the probability of spreading anthracosis to other plants is high.

Rust

If the temperature and humidity are not high enough, rusty formations may appear on the leaves. They usually spread on the underside of leaves. If you often spray the anthurium, the disease can be given a boost, and it will spread rapidly. If rust is detected, reduce humidity and increase room temperature. The leaves are wiped with a fungicidal solution against rust. With the further spread of spots, you will have to trim the affected parts of the plant.

Root diseases

Indoor flower anthurium disease is often affected when improperly maintained. As a rule, they are not infectious and can be easily eliminated by simply changing the conditions of detention. Roots are most exposed to external factors. Such situations are dangerous for them.

Now you know, having a sick anthurium, how to care. Diseases can be detected in the early stages. Providing attention, care and proper treatment to your pet, you will keep it healthy and beautiful.

Anthurium (flamingo flower) is another “foreigner” that has long taken root in the apartments of residents of our latitudes. it amazing plant – a native of subtropical and tropical latitudes. It is difficult to care for him, but even this does not stop gardeners who want to grow it at home. A common problem that owners of a flamingo flower face is the darkening of foliage. Why Anthurium on the leaves brown spots and how to deal with them? We will give qualified advice on this issue.

Causes of spots on the leaves of anthurium

  1. Natural aging. At some point, the leaves age and die. When this happens, they turn yellow, then turn brown and die over time. This is a normal process. You can leave the old leaves on the plant, giving them the opportunity to fall on their own, or carefully trim them. Sterilize the scissor blades with alcohol before trimming. You can pinch off dead leaves manually.
  2. Direct sunlight. Brown spots on the leaves of anthurium may indicate a sunburn. If the flower is standing under the sun on the window, remove it from there. A flamingo flower loves bright light, but does not tolerate direct sunlight, burning its foliage. It can be placed on a pedestal next to a curtain-curtained window on the sunny side of the apartment. Do not put the flower in a dark place, as growth will slow down due to a lack of light, problems with flowering will appear.
  3. Lack of nutrition. If the plant began to grow more slowly, new leaves are less and less, and old ones begin to grow brown and die, perhaps it lacks nutrients. The appearance of brown spots on the leaves is caused by a deficiency of the main macronutrients: nitrogen, phosphorus, potassium, calcium, magnesium. If the problem is due to nutrition, you will solve it with liquid fertilizers in a few weeks.
  4. Root rot. Healthy roots have a pinkish or whitish hue. If they or their individual fragments become brown or black, then the rotting of the root system has begun. The plant looks sick, leaves and shoots begin to darken, fade and die. Rotting of the roots occurs due to poor drainage (or its complete absence), as well as due to excessive watering. Anthurium should be transplanted, after trimming all diseased roots with sterile scissors.
  5. Salt deposits in the soil. Excessive top dressing by irrigation with hard water – this leads to salinization of the soil and the appearance of brown spots. The accumulated salts must be washed. To do this, put the anthurium in the bathroom and fill the soil with water at room temperature (the amount of water should be equal to the volume of the pot in which the flower sits). Water is poured gradually, allowing it to run through the entire pot – so it will wash the soil from excess salts.
  6. Lack of moisture. In nature, anthurium grows in the tropics and subtropics, where it rains almost daily and high humidity. Provide him with regular watering. You can water the flower a little every day, but for this, the pot must have a good drainage layer, otherwise the roots will rot. Due to lack of moisture, the tips of the leaves turn yellow, then turn brown and dry.

If the anthurium has brown spots on the leaves, see if the plant is infected with aphids or spider mites. Carefully inspect the flower for larvae. To cure a flower from aphids, you can use a solution of tobacco, in severe cases, apply actellic or karbofos. Sometimes a problem can be caused by a fungal disease. It is recommended to remove damaged leaves and provide the plant with full care.
