Typically, the daylily varieties bloom in May or June, displaying a beautiful show of flowers for three to four weeks. But what if you want them to keep beautifying your garden’s beauty for a little longer? Here’s what you must do to have your daylilies blooming all summer:

To ensure that your daylilies bloom across summer, you must be careful with the location where you plant them. It is a mandatory prerequisite to get the best blooms. So, look for a spot that meets the following prerequisites:

  1. The chosen area should receive at least six hours of sun daily for the plant to bloom. So, pick a spot that gets adequate sunlight in the morning, followed by part shade in the afternoon.
  2. Ensure that the planting area has access to fertile and healthy soil for the plant to grow fast.
  3. Even though daylilies are tolerant and adapt to the soil where you plant them, they enjoy slightly alkaline, well-drained soil with ten to eighteen percent moisture levels.


2. Pick the correct mix of daylily varieties

For your daylilies to bloom across summer, you must be cautious with what varieties you choose because not all daylilies will blossom across the summer.


Most daylilies have a three-week summer blooming season, and they vanish after that. But some of them can bloom all summer. These include:


  1. Pardon Me
  2. Apricot Sparkles
  3. Stella De Oro
  4. Happy Returns
  5. Fairy Tale Pink
  6. Dynamite Returns
  7. Night Embers


These daylily species do not bloom once. Instead, they bloom continually or intermittently from May through September. Hence, planting these blooms can be a good idea as they repeatedly bloom sans any break between the two rounds of flowering.


However, in some varieties, there may be a brief break. Consequently, the flowers will appear in early summer and continue showing across the season before they finally drop at the onset of fall.


However, you can find various other varieties beyond the above-listed seven daylily species. Their shapes, colors, and size may vary, but proliferation is standard amongst daylilies. Beyond that, several flowers grow on a single stem.


So, in only a single summer month, you can see hundreds of blooms on a large clump. Hence, we recommend opting for different types of daylilies to ensure that you have blooms across the summer season.


3. Select the right time for planting daylilies

If you wish to have colorful blooms across summer, you must plant them in early spring or early fall. You must plant them at least six weeks before the summer season, but growing earlier also works.

  2. Make a decently large hole to accommodate the roots.
  3. Ensure that the plant is buried in approximately an inch of soil at its crown where the roots and the leaves coincide.
  4. When tamping the soil to get rid of the air pockets, add the soil around the roots slowly.
  5. Pack the soil around the plant after you finish seeding it. Here is a detailed guide on how to grow daylilies from seeds.

Maintenance is the key and a crucial step in learning how to keep daylilies blooming all summer. Here are the steps for good growth and maintenance of your daylilies:


  • Water – You must regularly water your daylilies during the first season to get them started. However, once the daylilies establish, you must water them in arid conditions.
  • Mulching – Daylilies can significantly benefit from mulching. It can help avoid weed emergence, reduce soil erosion, and help retain humidity. You must apply a thick mulching layer right at the root zone. Please do not cover the crown in the process.
  • Fertilizing – You must fertilize the daylilies with extended-release fertilizer in late spring. It can significantly boost the blooming period. The right plant food can help you enjoy all-season blooms.
  • Pruning and trimming – Whenever you spot the fattening seeds, you must instantly remove them. Seed production does not let the new flowers grow as seeds direct all the plant’s resources toward it, preventing the blooms from appearing. Thus, chop every scape to the ground to ensure no buds are on it.


While trimming, you must also chop the yellow leaves during the season. It will facilitate the growth of new leaves on the plant. You can get rid of the spent leaves by pulling them. Similarly, you can also pluck the spent flowers to maintain the plant’s appeal.

Why Don’t My Daylilies Bloom All Summer?

Daylilies Bloom All Summer


Many home gardeners wonder how do you get daylilies to bloom all summer. If you too are experiencing a situation wherein your daylilies do not bloom, it might happen because of an umpteen number of reasons. Here are some of them:

  1. Move them to an area that receives better sunlight. If the plants near the daylilies have grown and started shading it, the daylilies might be unable to get access to the required sun. Hence, it might not yield blooms. Thus, you might consider moving it to a sunnier spot to kickstart re-blooming.
  2. Even though they are not susceptible to insects or pest attacks, a disease might invade them and cease blooming.
  3. Daylilies stop blooming when crowded by strong plants. You can know if the plants in the vicinity are growing fine and producing adequate flowers, but your daylilies do not bloom.


In this case, you should consider relocating the daylilies to a spot where it does not have to compete with others for nutrients, soil, and sun. It is a more common concern if you grow the daylilies near fast-growing plants whose roots expand rapidly and start intruding into the daylily’s area.

  1. At times when the plant becomes fuller, it might not yield flowers. So, you can consider thinning it and planting smaller sections. It will give your plant ample space to spread, grow, and bloom.
  2. If you thin out your plant in the wrong period, it might also affect its blooming. For instance, if you prune the large clumps in the daylily at the end of fall, it does not give the roots enough time to spread and prepare for blooms.
  3. Lastly, if your daylilies did not bloom since you bought them, ensure that the weather conditions in your locality are conducive for the daylilies. If not, you should probably try a different variety.


What To Do When Daylilies Have Finished Flowering?

After the daylilies finish flowering, you must still ensure they look their appealing best. So for the right post-bloom daylily care, snap the spent flowers, ensuring you do not disturb the buds.


Once the flowers are done blooming, cut them to the ground to ensure the plant looks neat and directs its energy toward seed production. It can also encourage the plant to yield more flower spikes.
