Cutting back Daylilies will keep the plant healthy and produce flowers year after year. Spent flowers and stems can be removed during the growing season to promote more blooms. Keeping with their low-maintenance sensibilities, Daylilies do not require much pruning, and generally, just cleaning the plant up to remove spent growth once a year is enough.
When to Prune Daylilies
The time varies by the variety, but most of the flowers on a Daylily only bloom for a single day. The plant will generally bloom for about a month to a month and a half, with new flowers opening up each day. Spent or dead flowers typically fall off naturally, but any that remain on the plant can be removed. Removing dead flowers or deadheading the plant will help promote new blooms.
Daylilies only need to be cut back once a year, but there are only two times when it is okay to prune the plants. The best time of the year to cut back Daylilies is in the spring or the fall. It comes down to your preference and what is easier and more convenient for you.
How to Prune Daylilies
Step 1 - Remove spent flowers and stems that do not have buds during the growing season
Gently tug dead flowers or use pruning shears to remove the spent blooms and stems.
Step 2 - Cut back spent growth in the late fall or early spring
After the first hard frost or early in the spring, you can remove all dead leaves.
How To Prune For Winter/Spring/Fall/Summer
It isn’t necessary to trim or shape the plant in any way; just cut back Daylilies to remove dead growth. Spent flowers can be removed throughout the growing season. All greenery can be cut back in the fall at the end of the season or early spring before new growth emerges.
Why Do You Prune Daylilies?
Deadheading Daylilies will encourage flowering. Removing the greenery either at the end or the start of the season promotes air circulation and allows the plant to start the next growing season strong.
