Fertilizing African Violets – Learn How To Feed African Violet Plants
African violets are one of the most charming blooming houseplants available. They have a sweet, old-fashioned innocence that appeals to everyone. There are just a few straightforward rules for growing African violets. Water and light needs are two of these, but just as important is how to feed African violet plants. The type of food is crucial when feeding African violets because some sources say nutrients can actually harm the plant.
Do African Violets Need Fertilizer?
African violets are fairly low maintenance. They do need proper exposure, heat and keep water off those leaves, but they usually keep producing those sweet flowers much of the year. To keep your violet in good health, it needs to be fed. When, how and with what are questions we will be answering.
Almost all plants need proper macro- and micro-nutrients as well as soluble vitamins, and African violets are no exception. African violet fertilizer needs to be water soluble and in a ratio especially developed for the plant’s
The best time for fertilizing African violets is in spring when the plant is actively growing. Avoid feeding African violets in winter. Some growers say not to fertilize the plants during bloom while others tout the process. However, considering that blooming deprives the plant of energy, it would seem logical that the nutrients used need to be put back into soil for plant uptake.
About African Violet Fertilizer
Not all plant foods are alike. African violets need a certain percentage of nitrogen, phosphorus and potassium plus trace minerals. The recommended ratio for African violets is 14-12-14. There are commercial formulas available specifically for fertilizing African violets, but many of these use urea as the nitrogen source. In certain conditions, urea can burn the plant’s roots.
A formula that uses ammonium nitrate may be a little bit more costly but is gentler on the roots. In instances where the plant is not blooming well, use a formula with a higher amount of phosphorus.
How to Feed African Violet Plants
These little plants need feeding every 4 to 6 weeks during their growing period. Prior to feeding, moisten the soil well. Use a liquid or soluble powder formula that will provide instant delivery. If you are using a concentrated liquid, follow manufacturer’s instructions for dilution.
Municipal water supplies can contain chlorine and should be allowed to sit for 24 hours before preparing African violet fertilizer. Excess chlorine is toxic to the plants. For a more organic route, you can also use worm castings, diluted compost tea or fish emulsion. These are primarily nitrogen, however, so add a little bat guano, which is available to purchase.
To avoid the build-up of toxic salts deposited in soil, flush the container at least four times per year and wipe the crusted salts from around the top edge.
Fertilizers for African Violets
When you plant your African violet in special potting soil, it is great chance that you don’t have to fertilize your plants for awhile. On the other hand, reduced growth and flowering with gradual loss of leaf color indicates that African violet plant needs more nutrients. Since African violets like rich soil, don’t wait for your African violets to look miserably before you start to apply fertilizers. If in doubt (with good reason – too much fertilizers can ‘burn’ roots), fertilize one or two plants and wait two weeks to see plant’s reactions. If plants start to grow again, leaves become darker and flowers become visibly stronger and healthier, fertilize the rest of the plants.
During vegetative period, African violets should be fertilized using balanced formulas like 7-7-7, 12-12-12 or 20-20-20. In blooming period, African violets need more phosphorus and fertilizers like 8-15-8, 15-30-15 and similar are more appropriate. When treated well, African violets can bloom almost year long.
Forms of African Violet Fertilizers
Fertilizers can be found in the form of:
– water-soluble pebbles,
– pebbles and plant food sticks/spikes with gradual release of nutrients,
– fertilizers in liquid form.
Water soluble fertilizers are usually applied once a month, according to manufacturer’s recommended dosage. To avoid spikes in nutrient content, it is also good practice to mix one forth or one fifth of regular fertilizer dosage with water and use this mix when watering plants. Discard excess water and fertilizer mix that drains from the drainage holes – don’t feel ‘sorry’ for this waste :o)
Most of these fertilizers can be applied (mixed) directly to the soil, too, but this way, we are risking development of burns on roots due to local high concentrations of fertilizers. If you are unsure, apply fertilizers as directed by manufacturers.
Fertilizers in the form of pebbles and sticks with gradual nutrient release are great for any plant, African violets included. They are added to the soil usually every 3-6 months (again, read instructions) and in this period you don’t have to worry about fertilizing your plants. It is very hard to over-fertilize plants using these two kinds of fertilizers.
However, they are also more expensive when compared with ‘ordinary’ water-soluble fertilizers.
Fertilizers in liquid form are very handy – you simply mix them with water and water the plants – like fertilizers in pebbles soluble in water, just don’t have to worry about mixing, dissolving and similar. Very often, this fertilizers are used whenever plants are watered – there are no spikes in nutrients in the soil, root system is kept healthy and plants take from the soil what they need. They can be more expensive when compared with other fertilizers in regard of nutrient content per gram, but if you don’t have (literatelly) dozens of African violets or any similar flowering plants, you don’t have to consider the price – and even then, simplicity of fertilizing plants this way justifies usage of this kind of fertilizers.
What ever fertilizer you use, be careful regarding amounts – as said before, too much of anything is not good, fertilizers included. Over-fertilized African violets can die due to problems with root system. They also develop tight centers with plenty of small leaves having rusty appearance. Be careful and read instructions that can be found on every fertilizer’s package.
Recommended African Violet Fertilizers
You can find suitable African violet fertilizer in almost any larger garden center – just be aware of your African violet needs (both NPK and microelements).
But if you are really into the growing African violets (having few pots or few hundred pots), using fertilizers specially formulated for African violets is highly recommendable. They are maybe little bit more expensive (just maybe), but usually worth every (euro)cent. Here are several recommended AV fertilizers that one can use at home not only for African violets, but also for other blooming flowers – of course, there are many others on the market that do their job well!

Back in the year 1894, Baron Walter von Saint Paul carried a flowering plant to Germany from East Africa, and he called it the “Usambara Violet.” Little did the Baron know that so many people would eventually fall in love with that flower that we now know as the African Violet.
Nowadays, these plants are very popular, and many consider them as prized plants. But what does it take to grow these plants? Well, aside from the basics such as air, water, and sunlight, you also need the best fertilizer for African Violets.
When it comes to fertilizers, these products keep on changing to suit the needs of various plants. In this article, we’ll help guide you so that you can find the best product to help your plants thrive. Read on and learn more about best fertilizer for African Violets.
Why your African Violets Need the Best Fertilizer?
The best fertilizers on the market must contain the basic macronutrients which African Violets need to thrive namely nitrogen, potassium, and phosphorus. Some products even contain other macronutrients such as magnesium and calcium. If you want your plants to get all the macronutrients they need, then supplementing their growth with fertilizer will go a long way.
Also, if you use water from reverse osmosis, rain or tap water, search for a fertilizer which caters to such situations. The presence of the macronutrients in the fertilizers will help keep the plants healthy and also help them produce better and more colorful flowers.
Aside from the macronutrients, some fertilizers will also provide your plants with a number of micronutrients. These are also essential in the healthy growth of plants but in smaller amounts. One essential micronutrient to look out for if you have soil with a high pH level is sulfur. This can help lower the pH level of the soil, especially in the plant’s root zone.
Fertilizers which have micronutrients are especially important for those who use reverse osmosis or rainwater on their plants. With such water, your African Violets will benefit a lot from a product which contains all the micronutrients they need to thrive.
The best way to promote the growth of African Violets is to give them the right fertilizer or plant food each time you water them. This will help you remember better when to fertilize your plants since you’ll do it at the same time you water them. You can use almost all kinds of fertilizers this way, but it’s still best to follow the instructions of the product you’re using.
The best fertilizer for African Violets will promote better growth, a higher survival rate, and more blooms. While some fertilizers are suitable for all flowering and indoor plants, others are specifically meant for African Violets. Either way, using a fertilizer will help move things along and make your plants healthier and more productive.
What To Look For In a Fertilizer for African Violets
The essential nutrients
A good fertilizer should contain fairly equal amounts of the most important nutrients namely nitrogen, potassium, and phosphorus. You should find these components on the product’s label with their ratios in numerical values. The values for standard sizes and varieties of African Violets would differ from the values for miniature African Violets or other special varieties.
The three essential nutrients are part of the 16 vital elements required by African Violets and by other types of plants so they can grow and reproduce normally. The other vital elements are calcium, carbon, boron, copper, chlorine, iron, manganese, magnesium, oxygen, sulfur, zinc, hydrogen, and molybdenum.
Among all these elements, you may also commonly see sulfur, magnesium, and calcium listed as part of the fertilizer’s components. On the other hand, oxygen, hydrogen, and carbon, known as the free elements, are normally acquired from the water and the air.
It’s also important to choose your fertilizer according to its nutrient source. The cheapest ones have urea nitrogen as their source, but these fertilizers aren’t very desirable especially for those who grow plants in cold areas. This is because using such fertilizer would most likely result in your plants acquiring ammonium toxicity. This happens when the bacteria in the soil become inactive when the temperature gets cold, and they aren’t able to adequately process the urea content.
Therefore, it’s better to go for products which use ammoniacal nitrate or nitrogen as a nutrient source. These are a bit costlier, but they have better quality and won’t pose any problems.
If it’s your first time to purchase fertilizer for African Violets, then you can ask your neighbors and other people in your area which product works well for them. You may even have to use different products at different times of the year depending on certain factors.
Another factor to look for in the best fertilizer for African Violets is the water solubility. Make sure that the product you choose is completely water soluble as this is very important. This feature will allow the plant to absorb all the important elements that the fertilizer contains.
Also, the water-soluble feature is especially important if you plan to use a self-watering device for your plants. In such case, the elements will only go into the soil if they’re completely dissolved.
Fertilizers come in different forms. Among all these forms, the concentrated liquids and the soluble powders are most recommended. Between the two, people often prefer soluble powders because they’re more cost-effective in the sense that they don’t have the added cost associated with the water’s weight that’s added to the concentrated liquids.
Of course, both forms have their own benefits. Soluble powders are easy to mix and some even come in pouches which are already pre-measured. For concentrated liquids, they’re more convenient especially since you can use them with self-watering devices.
No matter which one you select, don’t forget to consider the fertilizer’s water solubility. Whether in powder or liquid form, this is an important feature since it will allow your plant to get all the nutrients and components which will help it become healthier and produce more blooms.

Question: What is the best fertilizer to use on African violets?
Answer: The answer is ever-changing, because fertilizers seem to come and go frequently. The best fertilizer for you will depend on the source of the water you are using and what is or isn’t in the water as well as the pH of your water. The temperature of your growing area may also affect your choice.
Almost all fertilizers offer the basic three “macro-nutrients” of nitrogen, phosphorus and potassium which are needed in ample supply for healthy plant growth. A few also include the “macros” of calcium and magnesium. Since these two latter “macros” are found in many city water supplies, most growers will get enough calcium and magnesium from their water. If you use rain, distilled or reverse osmosis water, be aware that you need a fertilizer that contains both, or you will need a supplement (commonly called Cal/Mag) to supply them. In the past, many growers chose fertilizers with a high “middle number” (phosphorus) because it promoted blooming. There may be some value in boosting phosphorus briefly if you are a show grower, but be careful because too much can damage foliage and hurt the plant.
Many fertilizer brands also have and list “micro-nutrients” which are needed for healthy growth, but in very small amounts. Not all brands list the “micros” but they can be very important. Sulphur, for example, tends to lower pH in the root zone. If you have problems with high pH (over 7), a fertilizer with sulphur will help you control your problems and bring your pH into a more desirable range of 6-7. But if your pH tends to become too acid (below 6) then sulphur will make the problem worse. If you use well water, or live in mining regions where your water supply may carry high amounts of specific minerals, it is possible for your violets to show symptoms of toxic levels of a micro-nutrient. This may cause irreversible stunting of center growth which looks very much like the violet has mutated to a miniaturized version of the original. It helps to know what your local water supply contains and to choose your fertilizer accordingly. If you use rain, distilled or reverse osmosis water, you will want a fertilizer which promises all the micronutrients needed.
Choosing a fertilizer according to the source of the nutrients is also wise. Fertilizers listing their source as urea nitrogen are often the cheapest and also the least desirable. If your growing area is frequently colder than 70 degrees Fahrenheit, a fertilizer made from urea is more likely to result in ammonium toxicity. This is because the mycorrhizae (soil bacteria which process nitrogen) are too inactive at cold temperatures to process the urea adequately. Fertilizers using ammonical nitrogen or nitrate are a little more expensive but are generally better quality less likely to pose problems.
It is often wise to ask others in your area which fertilizer works best for them. Some growers like to rotate and use different fertilizers during the year, using balanced formulas during times when more growth is desired and high phosphorus formulas when preparing for show.
Fertilizers currently (2018) being mentioned by many growers in social media (especially to use with rain, distilled or reverse osmosis water) include either DynaGro Grow 7-9-5 or Feed Me MSU fertilizer for African violets (from repotme.com). Also recommended is Better Gro Orchid Plus 20-14-13 without urea, which is also preferred by many growers of other Gesneriads. Jack’s Classic formulations generally lack sulphur and may be useful for growers with acid growing conditions. As always, read and follow package directions (do not exceed recommendations) for best results.
Question: Is it okay to use a fertilizer with urea? I use fluorescent light and average 24 degrees (centigrade).
Answer: Urea-based fertilizer should not cause problems for you if 24 C is your usual temperature for growing. The exception to that would be if your soil pH were quite acid. Even then, the symptoms of ammonium toxicity (the result of using urea-based fertilizers in cold or acid conditions) are generally seen on the leaves or in the root system. Happy Growing! Joyce Stork
Question: The only peat moss I have found in bags also has fertilizer in it. Can I still use fertilizer in the water every time I water or will this be too much? 2)The fertilizer I have is 12-14-12 and says to use 1/2 tsp per gallon of water. Should I dilute it even more then? 3)I haven’t found any peat moss without fertilizer unless you can use the kind you buy in bales that you would use in the garden. If you use this kind I thought I read somewhere about having to sterilize it. Is this true and how would I go about it?
Answer: 1)If you have no choice except for the fertilizer-charged potting mix, then you do not want to fertilize for about three months. This is why we dislike charged mixes… you really don’t know at what point you should begin fertilizing. 2)If the fertilizer recommends this rate for once a month fertilizing, and you are going to use it weekly, you should dilute it to no more than an 1/8 tsp per gallon. If this is their recommendation for weekly watering, I would still dilute to 1/4 tsp and then watch. If you see fading vigor then a bit more might be good. However if you see yellow spots or edges around the perimeter of the older leaves, you are over-fertilizing and need to cut back the rate of feeding. 3)If you choose a bale that has no tears or cuts, the peat should be safe to use. Rather than sterilize the potting mix, the goal is only to pasteurize it which is done by heating the damp mix to 180 degrees and holding that temperature for thirty minutes. Sterilizing it (at a higher temp) would destroy the beneficial bacteria that enable the roots to absorb nutrients.
Question: I was told to water my African violets with warm tea. What does this do and is it okay? What brand name fertilizers are okay to use on these plants, as mine have great foliage but are not blooming although I have them in a window with north light.
Answer: There isn’t anything obvious in tea that would be beneficial for African violets, although some teas might help amend the pH or provide some nutrient that the African violets need in tiny quantities. I would be very careful about using “warm” tea, since it is not good for a plant to have a sudden change in the temperature around the roots… a change of more than ten degrees (either colder or hotter) can result in spotting on the leaves because of root damage. There are a number of good African violet fertilizers. Use this according to package directions, erring on the side of using less rather than more than recommended. In a north window, you may not be getting enough light to the plants to get them into good bloom. The ideal window seems to be an east-facing one in which the plant receives bright morning sun. On the north side, the window must be fairly large and the African violet must be sitting so that it almost touches the glass. Having a building nearby that reflects light into the window can also really enhance the quality of the light. If you suspect inadequate light, you may need to supplement it with a little artificial fluorescent light for up to twelve hours a day. For more blooming tips find the article “Blooming Secrets” on the AVSA web site. Happy Growing! Joyce Stork
Question: The first time I repotted my African violets, I lost some plants due to shock, I believe. How can I prevent root shock? Will extra Superthrive help?
Answer: Many growers do use Superthrive with good results, but I would not recommend using more than the package suggests. I find that I rarely have shock if using a light porous potting mix (equal parts of sphagnum peat moss, perlite, and vermiculite) and if the plants are enclosed in a clear container or bag (set away from direct sunlight) for about one month after transplanting. Happy Growing! Joyce Stork
African Violets, like other houseplants, need a little tender loving care by giving them an occasional dose of fertilizer. You can buy African Violet liquid plant food, or you can also make your own easy DIY homemade African Violet fertilizer from common household items.

Is Vinegar Good for African Violets?
Vinegar is useful for increasing the acidity level of your soil. To determine the acidity of any soil, you will need an inexpensive soil testing kit. African Violets require soil with a pH level between 6.0 and 6.5.
If the pH level of your soil is above 6.5, the acidity level of the soil is too low. You can add vinegar to the soil to lower the pH level of the soil and increase the acidity. The best way to add vinegar to the soil is to add 2 tsp. of white vinegar to 1 gallon of water. Water as usual.
Keep in mind that African Violets don’t like to be watered like other houseplants. They like to be watered from the bottom, not the top. Find out more tips about African Violet care.
You will need to re-test your soil every week until the pH level is between 6.0 and 6.5. When the soil reaches the correct pH level, discontinue adding vinegar to the soil.
Is Hydrogen Peroxide Good for African Violets?
Some people swear that hydrogen peroxide encourages African Violets to bloom more often. Add a capful of hydrogen peroxide to 4 cups of room temperature water and then water as usual. If the plant has any kind of fungus, the peroxide will also kill it.
Homemade African Violet Soil
African Violets do require special soil. You can purchase potting soil that is just for African Violets. If you would like to try making your own potting soil for African Violets, then mix together 1/3 regular potting soil, 1/3 peat moss and 1/3 perlite or vermiculite.
