Mail Order: What To Expect

Plants you receive by mail need time to adjust. Your plants will arrive in bundles. Upon arrival, they may not appear lush but given time & proper care, they will flourish!

Planting Instructions

The rhizome (root) of your Blue Flag Iris needs to be positioned in the aquatic planting media so that the cut end tuber is against the side of the planting container, not in the middle. This gives the root as much room as possible to spread across the planting container. Avoid using bagged potting mix and other lightweight soils because they will float and continually cloud pond water. Place planting container on the planting shelf in up to 6″ of water depth.

Regular fertilization of your Blue Flag Iris will keep it growing well all season long. CrystalClear® Thrive™ Fertilizer Tablets can be pushed into the soil at planting time and from April through August, see label for fertilizer application rates.

Plant Maintenance

For best results, trim or prune as leaves and flowers begin to turn yellow or brown, remove them completely, discarding them to keep as much excess organic material out of water-body as possible.

Winter Care

All leaves and stems will begin to die off as winter arrives. If planted directly into a bog area, plants should be left alone after trimming any dead foliage to 1 to 2″ above the top of the water. Plants that are on plant-shelves, in planting containers, should be trimmed to 1 to 2″ and then gently lowered into the ponds deeper water. All plants submerged before winter must be brought back up as soon as the ice has permanently thawed, and before any plant growth occurs. In Zones 6 and warmer, most pond plants can tolerate being left in place without moving them at all.

Water Iris Information – Learn About Water Iris Plant Care

Ever heard of water iris? No, this doesn’t mean “watering” an iris plant but pertains to where the iris grows – in naturally wet or aquatic-like conditions. Read on for more water iris information.

What is a Water Iris?

Although several iris types grow in wet soil, true water iris is a semi-aquatic or bog plant that grows best in shallow water deep enough to cover the crown year round. However, most water iris plants will also grow in wet soil alongside a pond or stream, or even in a well-watered garden spot.

True water irises include:

  • Rabbit-ear iris
  • Copper or red flag iris
  • Siberian iris
  • Louisiana iris
  • Yellow flag iris
  • Blue flag iris

Water Iris Growing Conditions

Planting a water iris in a wide pond plant basket or plastic pot to confine the growth is advisable, as some types of water iris, like yellow flag irises, can spread like crazy and may become difficult to control.

Look for a location where the plant is exposed to sun for most of the day, unless you live in a hot, desert climate. In that case, a little afternoon shade is beneficial.

If you don’t have a pond, try planting water iris in a whiskey barrel lined with plastic. The water should cover the crown by no more than 4 inches (10 cm.).

Although water iris can be planted nearly every time of year in warm climates, autumn is the optimum time in other regions, as it allows time for the plant to get settled in before the arrival of cold weather. If the weather is hot, provide afternoon shade until the roots are established.

Water Iris Plant Care

Fertilize water iris plants regularly throughout the growing season using a general-purpose aquatic fertilizer to encourage healthy growth of roots, foliage and blooms. Alternatively, use a balanced, slow-release aquatic fertilizer.

Water iris generally remains green all year in warmer climates, but any yellow or brown leaves should be removed to keep the plant healthy and the water clean. Cut water iris to just above the water line in autumn if you live in a cooler climate.

Repot water iris into a slightly larger container every year or two.

The Yellow Iris, also known as the Yellow Flag Iris, is a true aquatic plant that is native to England. It is the only yellow-flowered iris and reaches 28 to 38″ in pots and up to 48″ in the wild. It may be grown in up to 12″ of water.

The Yellow Iris has bold, deep green to gray-green vertical foliage and 4 to 12 brilliant yellow flowers per stem. The number of blooms is directly related to the amount of dampness the iris is grown in and how close each plant is to the next. The blooms may have brown to purplish veining on the petals.

This iris normally blooms from May into June. Planting in clumps produces lush, thick stands, but will also reduce the number of blooms per stem. Seeds germinate freely, so clip off seed heads before fully mature to reduce unwanted spreading.

A very hardy plant, the Yellow Iris should be wintered outside in the pond. In northern climates, cut back the dead foliage to just above the water line, southern grown plants may remain green all year. Divide and repot this iris in the fall or after the bloom season. Zones 4-11.

How to Plant Iris flowers correctly is not difficult. I share my technique on how I plant Irises for the best flowering and healthy plants for years of enjoyment.

I have shared plenty of the iris in my garden and I thought to share how I plant bearded iris for those that are beginners in gardening or with Iris flowers.

Sometimes I forget that not everyone knows the ins and out of planting and caring for different plants.

I am reminded when I give some to a friend and they end up killing them because they really did not know the right way to plant Iris bulbs and I failed to tell them.

So here you go, How to plant iris correctly yet easily!

When to Plant Irises

Iris are usually shipped from growers in August and September.

This gives most gardeners the chance to get the in the ground in time for the rhizomes to settle in and start rooting.

This is also the time that you would dig up and divide your currently growing Iris in your garden.

After you have either dug up and divided your rhizomes or you have just received some from an iris farm you need to plant them correctly to get the most from them.

If you need to know how to divide your Iris rhizomes before planting I have you covered here.

Here are my latest ones…

At the end of this post I will have a list of sources for you.

Garden Location for Iris flower planting

Pick a spot in the garden that gets a good 6 hours of sun each day and has good drainage.

Iris can withstand drought but not soggy feet.

Note: You can plant them with other plants that like more water by planting them in small hill of soil. They can drain off while the other plants get all that water.

My favorite tool for digging and planting Iris.

Prepare the Soil

I have sprinkled some bulb fertilizer on top of the soil.

Stir the fertilizer into the soil, mixing it in lightly. I mix the fertilizer in to the soil rather than just placing in the hole.

Rain fall will deliver the fertilizer where it needs to go.

An Iris or Bulb fertilizer can give your plants a head start. This is my favorite.

How to Plant Iris Rhizomes

Plant your Iris rhizomes in the soil you just mixed the BulbTone into making sure to keep them close to the surface.

Note: I have been battling voles this year. They have been eating my plants including the Iris rhizomes, to deter them eating my newly planted Iris I put some of this under and around the rhizome.

Do not bury deep your Iris rhizomes too deep.

This is the mistake many make. Iris like to be close to the surface.

I leave a bit of the tops showing when I plant, that way I know they are not too deep.

Iris love the sun on their backs, the top part of the rhizome. If you live in a very hot area you can cover the backs of the rhizomes lightly with soil.

In cold, cold climates do mulch a bit before hard cold starts but be sure and rake it back as soon as warmer weather begins.

When replanting Iris that I have divided I like to plant three together.

Plant them with the pointy nose of the rhizomes facing each other in a circle. Spacing is not critical but I like to place mine about 3 inches apart.

I firm them in with my foot, you can see my footprints in this photo.

Planting them this close together means you will get a good show of blooms next Spring but you will also need to divide them sooner than if you planted the further apart.

Above the soil is moist but if you are doing this during a drier part of the year water them in and keep watered through the summer but not soggy.

If you are planting a newly acquired rhizome you will most likely only have one, and that is fine. Plant it the same way just not in a grouping.

In a few years you will have enough to divide and replant.

Next Spring you will have some lovely Iris to enjoy.

Most reputable Iris farms and gardens send out good sized rhizomes that will bloom the first year.

When dividing your Iris you may have some smaller sized ones attached to the larger rhizomes.

The smaller ones will many times take another season to grow in size before blooming. So don’t get discouraged if yours don’t bloom the first season.

I hope this helps all those out there that were skittish about growing Iris.

Growing Iris is truly very simple and so rewarding.

Happy Planting!

Ask Dan: What are those ‘bulbs’ growing on iris stems?

Hey folks, the weather has gotten a little more normal over the past week. Some much-needed rains and cooler temperatures were definitely welcomed by many of us. Be on the lookout for powdery mildew. It may be attacking lilac, birch, squash and many other plants. A safe and effective treatment is spraying products containing sodium bicarbonate (baking soda), potassium bicarbonate or neem oil.

Q. I had a beautiful growth of flowering irises. They were really great this year. Now that the flowers have receded, I have large-looking “bulbs” (like a small potato) growing on the flower stems of the plants. Are these new seeds, to be used for next year’s planting? Angelo
A. The bulbs that have formed on the iris flower stalks are seed pods. The pods are often mistaken for new flower buds and are left to grow and develop, which takes extra energy from the plant.
To help keep your iris healthy and productive, you should remove the seed pods as they develop after flowering, or simply remove the individual spent iris blooms and prevent the seed pod from forming. The flower should come off easily.
However, be careful of the other buds. More than one bud can develop on a single stalk, and they may grow quite close together. Take care not to break off a new bud when you are removing a dead flower. Once all the flowers are done blooming, you can follow the stalk back to its base and simply cut it off This will keep the plant looking neat and tidy.
Q. I need to know if herbs should be fed as vegetables or flowers. Lisa
A. There’s nothing like the taste of herbs picked fresh from your own garden. They’re so easy to grow, whether in beds, borders, containers or on windowsills.
Herbs are relatively low maintenance unless they are growing in containers, where they will require routine watering and feeding. The feeding is the part you want to watch.
Vegetables and flowers are generally geared toward flower and fruit production, so the fertilizers that are made for them have different nutrient ratios. Usually they are higher in phosphorous and potash to encourage fruit production.
With herbs, its not the flowers and fruit you want, but more of the leaves. Use a general purpose fertilizer such as 5-5-5 or a 10-10-10 to encourage more leafy growth and not specifically flowers or fruit. Don’t think more fertilizer is better. Overfeeding can cause the leaves to lose their pungent flavor, so don’t overdo it.

Many gardens have them: wet, boggy areas that just don’t drain well enough. Grass won’t grow, plants won’t grow, and the dog keeps coming in the house with wet feet. OK, maybe just the plants are a problem for you. Either way, you could, of course, set up a rain garden in that area (it’s beautiful and great for the local environment), but that can be much more effort than many gardeners are willing to put in. You could give up and have a boggy, mulch-covered area in your garden, but I know that you, my readers, won’t give up that easily. The best option is to try to find plants that thrive in those difficult conditions, and many of the best plants for that purpose are wonderful Irises.

Give Iris louisiana a try. The do beautifully in damp soils, producing some of the most stunning blooms you can find. They’re the perfect solution not only for those areas that refuse to drain, but also for embankments of water features or other water sources (they look amazing on the banks of a pond). Best of all, they’re easy plants to keep, tolerating not only heat and humidity (as you can probably guess from the name), but also cold winters, some even hardy to zone 3. Iris ‘Bold Pretender’ makes an impressively bright, cheery statement in red and yellow, and it looks great next to the Iris ‘Black Gamecock’s intensely rich velvety purple flowers.

Advice – Which Iris should I plant?

Where to position different species of Iris plants

Pond shelf Iris will all grow with water over their crown:

Emergent Iris allow dragon and damselfly larvae to use the tall leaf growth to climb up and out of the pond water to emerge as adults.

  • Iris pseudacorus
  • Iris versicolor
  • Louisiana Iris

Iris pseudacorus will take more water than the others and will also cope if you plant them in wet mud . Iris versicolor and Louisiana varieties want less water over the top of the basket and will also grow in wet mud.

Iris robusta Dark Aura will grow well in waterlogged soil with its crown at ground level but able to withstand water around its roots and a small amount of flooding over its crown in Winter. It will also grow in good moist conditions . So it is part way between being a pond Iris and a moisture loving Iris.

Moist loving Iris:

These will NOT grow submerged in water or with their roots in wet waterlogged soil in winter.

  • Iris ensata – will handle wet soil in Summer but not in Winter
  • Iris sibirica – moist soil, not an area that will flood in Winter as this will rot their roots

Iris robusta Dark Aura Iris for planting in moist or wet mud areas Iris sibirica Rigamarole Iris sibirica Tropic Night

There can be an Iris of one variety or another in flower from May – July if they are planted in the sun. Starting with the versicolor and sibirica, then the ensata, laevigata and pseudacorus through June to the last Louisiana Iris in July.

Iris is a family of plants that will give much colour and flower shapes to enjoy over a long period of time if you give each one the conditions it enjoys.
