Pruning Daylilies: Simple Steps for Vibrant Growth

Welcome to our guide on pruning daylilies! Cutting back daylilies helps them stay healthy and tidy, especially when their leaves turn yellow or ratty. A good pruning can even give your daylilies a boost, encouraging fresh blooms and growth. In this article, we are going to cover everything about timing and how you should actually prune this plant. Let’s get started!

When to Prune Daylilies

Daylilies need pruning only once a year, either in spring or fall. Spring pruning clears out winter damage while cutting it back in fall prepares the plant for the next growing season. Both times work well, so choose what fits best with your gardening schedule. As far as deadheading goes, you want to do the during the growing season, specifically mid-summer.

The Tools You’ll Need

Before you start pruning, make sure you have the right tools for the job. You’ll need a pair of sharp pruners or shears to make clean cuts. These will help prevent any damage to the plant and ensure a healthy pruning process.

Gardening gloves are also crucial—they protect your hands from sharp blades and any rough or prickly parts of the plants. With these tools, you’ll be well-prepared to keep your daylilies looking their best.


Pruning Daylilies Step-by-Step

Now that we know why and when to prune, plus we also have our tools ready, it is time to discuss how to prune daylilies the right way.

Cutting back Daylilies for Winter

When the growing season ends and harsh weather rolls around, daylilies naturally die back to the ground. This is the perfect time to cut all dead foliage to prevent disease and prepare the plants for next season’s growth. Make sure to use sharp pruners and angle your cuts slightly to prevent water from pooling on the stems, which can lead to rot.

  1. Wait until the foliage dies back after the first fall frost.
  2. Cut the plant back to about 4-6 inches above the ground.
  3. Mulch around the base of the plant to retain moisture and protect the plant during winter.

Early Spring Pruning

If you missed cutting back your daylilies last fall, early spring is the perfect time to catch up. Aim to prune about six weeks before your last expected spring frost.

  1. Trim the plants back to the ground before any flower bud development begins.
  2. If new growth has already started, it’s okay to cut the old growth back; just be careful not to damage the new leaves.

Deadheading for New Blooms

If you have reblooming daylilies (such as “Happy Returns”, you can induce a second round of blooms by removing the spent flowers. Mid-summer – just after blooming is finished – is a great time to pull out those pruning shears once again. This is what you need to do:

  1. Wait until the flower stalks have completely finished producing new blooms.
  2. Trim off the main flowering stems at their base once no buds are left to open.


Depending on what kind of pruning you’ve done, you need to do some aftercare. If we are talking about regular deadheading, just make sure you give your daylilies enough water, and that they get enough direct sunlight (6 hours per day at least). Keep an eye on the soil moisture levels, especially during hot, dry weather, and mulch around the base of the plants to help retain moisture. Mulching also helps when you are done with cutting the plant back in the fall.
