Daylilies after flowering - tips for care, pruning, propagation in late summer!

Should you cut back the plants after flowering ? Do you need to fertilize them ? Is there anything you can do to make them bloom longer ? Can you divide them in the summer if they have grown too large? We will answer all these questions below. Many varieties of daylilies bloom several times a season. And with a little mid-summer care, you can make those blooms appear much faster. But no matter what variety you have, summer care is important for its long-term health and vibrancy. Not only does it help keep the foliage strong and beautiful throughout the long summer months, but it also helps the plants have a better, more vigorous bloom cycle the next year.

Remove the faded flowers

After blooming, it is important to remove any flowers that have already faded

After the first bloom , it is important to remove all the flowers that have already faded . In this way, you focus the energy of the plant on the production of new flowers. The entire flowering period can last from a few weeks to 45 days. This depends entirely on the particular variety of daylily. However, by removing old flowers, this time can be extended – regardless of which species you are growing. Unfortunately, if old flowers remain on the plant, they continue to consume plant resources. Resources that should and could actually be used for more flowers and brighter foliage. Removing old flower stalks can be done by hand, with sharp scissors, or with handy hand shears.

Removing stems and seed heads

Seed heads should be cut back to the base of the plant as they appear

Next, let’s talk about the seed heads and flower stalks of daylilies. This topic is especially important for daylily varieties that are ready to bloom again. Once daylilies finish their first bloom, they begin to form seed heads. These seed heads, or lily tips as they are sometimes called, are not necessary for the health and growth of the plant. But they do use up the plant’s resources to form and grow.

For this reason, seed heads should be cut back to the base of the plant when they appear. In this way, the plant will be forced to use its energy for new flowers and strengthening the plant, as well as by removing the faded flowers. For all daylily varieties, this is also a good time to give them some all-purpose fertilizer. This will help them build strong roots and energy for the next blooming cycle.

Propagate the plants in late summer

Have your daylilies grown too large? You can divide them after they bloom! This is a great way to keep them in shape and create a few new starts. When daylilies get too big and crowded, the bloom suffers. However, dividing creates lots of new space and new plants. Dividing daylilies couldn’t be easier. Simply dig up the plant and divide it through the roots with a sharp shovel. When dividing, use sharp shears or hedge clippers to remove all foliage down to the base of the plant.

What to do with my daylilies after they bloom in mid-summer

First of all, this foliage will most likely die when the plants are planted in the ground. So cut it off as soon as you dig it up so your plants don’t look sad in the bed while new growth starts from below. More importantly, cutting back this growth will spur the new plant to grow faster and encourage it to resprout much more quickly. Division can be done at any time, but always wait until the lilies are past their first main bloom before digging. Once the plants are transplanted, it will take about 3 to 5 weeks for good growth to appear in the crown. So take care of your daylilies after flowering and enjoy them all season long.
