Daylilies

Why Are Your Daylilies Not Blooming? (And How to Get Them to Re-Bloom)

If you are looking for a sturdy, low maintenance plant to adorn your landscape, you should definitely consider the daylily. Recognized for their beautiful floral displays, the flowers from daylilies come in an assortment of subtle and vibrant shades and hues.

The one downside to a daylily is that their flowers only last for one day.

What Is a Daylily?

Daylilies are perennials that are able to grow quickly and for long periods of time. They can grow in either shade or full sun and grace us with their display of big beautiful blooms from the middle of summer all the way until the beginning of fall. Gardening enthusiasts are able to enjoy a new display every day.

It’s best to get plants from a reputable nursery and even though the plants can take sun or shade, they seem to do best in full sun. They will grow in a container or planted directly in your garden or as a decorative border.

There are so many types of daylilies to choose from and just as many different colored flowers to look forward to seeing daily.

Why Are Your Daylilies Not Blooming?

What Causes Daylilies Not to Bloom?

One problem gardeners come across when dealing with these plants is when they fail to bloom. What happens to them that they aren’t able to produce their daily flower?

Here are a few simple reasons why your daylilies may not be showering you with their floral display:

  • They may need to be in an area that has more sunlight. If the lighting has changed in the area where they are planted, such as a tree has grown and now is producing much more shade, you may need to move the non-blooming daylily to a sunnier location.
  • Even though they are not usually bothered by any specific types of pests or insects, check to make sure that they have not been invaded by a disease of any kind.
  • Sometimes daylilies find themselves becoming too crowded along with other equally strong plants. If you find that the surrounding plants are fine and producing their own type of flowers, you may want to relocate your daylily plant to a place where it won’t have to compete for sun, soil, and nutrients in order to be at its best. This is especially true if the daylily has been planted near a fast-growing tree whose roots are expanding rapidly and taking over the daylily’s area.
  • If your plant seems to have grown fuller and is not producing flowers, try thinning them out and planting smaller sections. Make sure you give them enough room to spread out and grow and avoid becoming overcrowded again.
  • The time period when you thin them out may be preventing them from blooming. If you reorganize the large clumps in your daylily at the end of the fall it may not give the plant enough time for its roots to spread out and be ready to bloom.
  • If your plant has never bloomed since you purchased it, make sure that the daylily is able to bloom in your area. Look up the map that shows the best areas for the type of daylilies that you want to grow and that where you live is included in one of those areas.

What Is the Proper Way to Cut Back a Daylily?

If your daylily has stopped blooming because it has become too crowded, this is an easy fix. It is suggested that you trim the roots of your daylilies every couple of years to make sure that they continue to bloom without interruption.

When the roots of the plant get too full you have to divide them and replant them. You need to trim the leaves of the plant down to around 6 inches to make it easier. You have to loosen the dirt that surrounds the clumps so you can create several smaller plants from the one large one.

Once you are able to free the clumps from where they are planted, shake off the extra dirt to expose the single fans. Remove as much soil as you can so you can separate the clumps.

Create new places to plant the clumps about 18 inches deep and make it wider than the roots. Pile some dirt in the middle of the hole and put the crowns on top. Cover them with up to 1 1/2 inches of dirt.

How to Get Your Daylilies to Re-Bloom

There are several things you can do to get your daylilies to re-bloom.

  • Divide them and replant when they become overly crowded.
  • Make sure that you have the type of daylilies that are able to re-bloom. Several of these include: “Barbara Mitchell,” “Dragon’s Eye,” and “Stella de Oro.”
  • When you replant your daylilies make sure you keep them watered so they don’t dry out.
  • Plant them in a spot where they will get at least six hours of sunshine every day.
  • Put 2 inches of mulch over the top of your daylily so it will keep the soil from drying out and it will keep any weeds from taking over.
  • Remove any flowers or buds that are old and wilted. This will encourage new growth.
  • Use a slow-release kind of fertilizer that is low in nitrogen. Look for a 5-10-10 mixture and water the plant immediately after fertilizing it so it can soak into the soil for the most effectiveness.
  • At the end of winter, when your daylily is resting, cut your plant all the way down to the ground and remove any wilted or dead leaves so it will be ready to re-bloom in the spring.

Even with all of these extra instructions, daylilies are genuinely easy plants to take care of. Just a few extra steps will reap great rewards and you will get to enjoy beautiful blooms every day and even longer than you expected.

Choose a couple of different types of daylilies and you can wake up to a rainbow in your yard every day.
