Lilies make a lovely addition to any garden, and unlike a lot of plants, they don’t have to be pruned during their blooming period. Instead, wait until after they’re done blooming – usually after the first frost – to prune them. When you prune dying blooms, make sure you prune the entire stem, down to the base of the flower. If you notice dying foliage, look to see how extensive the damage is. If only the tips of leaves are browning, clip just the tips.

Deadheading Dying Blooms

  1. 1
    Deadhead dying blooms throughout the blooming season. If any of your lilies begin to wilt or look brown, you can deadhead them, even if the plant is still blooming. Depending on the variety of lily you have, removing dead flowers may encourage new growth. Even if it doesn’t, it will help make your lily plant and your garden look neater.

    Answer from Maggie Moran:

    Maggie Moran, a professional horticulturist, responds: "It is a good idea to deadhead lilies not only for the appearance of your garden but also to help the lily focus its growing energies to new blooms."

  2. 2
    Use small, lightweight shears to prune your lilies. Bypass pruners and grass shears both look like large pairs of scissors, but they're lightweight. They tend to make a gentler cut than other types of shears, which is ideal for delicate lily blooms. You can use the same shears to prune.[1]

  3. 3
    Follow the stalk of the flower into the base of the lily plant. Lilies flower at the end of a long stalk attached to the center of the lily plant. To “deadhead” lilies, you need to follow the stalk all the way down to the base. You may not be able to see into the center of the plant. If you can’t, use your hand to follow the stalk down.
    • If you’re feeling your way to the base, make sure you wear gloves.
  4. 4
    Cut the stalk at the base of the plant. Instead of pinching the flower off just behind the bud, you’ll want to remove it at the end of the stalk. Use pruning shears to clip the stalk right at the base of the plant. Get as close as you can to the base – you shouldn’t leave a stub.
  5. 5
    Disinfect your shears in between cuts. If you’re shearing dead or diseased blooms or foliage, it’s important to disinfect the shears in between cuts. Otherwise, you risk spreading disease to healthy parts of the plant. To disinfect, dip the blades of the shears into a solution of 1 part vinegar to 2 parts water.[2]

Removing Browning Foliage

  1. 1
    Leave yellowing or browning stalks until the fall. If you notice that some of the foliage is turning yellow, but not brown, leave it alone. The yellow stalks won’t affect the overall health of your plant, and cutting them down early actually decreases the amount of energy the plant can produce.
  2. 2
    Prune back yellow stalks after the first frost. Once the first frost has occurred, your lily plant no longer needs the energy produced by the foliage stalks. Use your shears to cut the yellow foliage stalks down to the ground.
  3. 3
    Remove entire stems of mostly brown leaves. If quite a few of the leaves on one stem are brown, you should remove the entire stem. Follow the stem to the base of the lily plant, then use pruning shears to cut off the entire stem. Be sure you don’t leave a stub at the base of the plant.[3]
  4. 4
    Clip the tips of browning leaves. If you notice that just the tips of the leaves on your lily plant are browning, you don’t need to remove the whole stem. Instead, make an angled clip just below the browning tip. The plant should grow a new healthy green tip.[4]

Article SummaryX

To prune lilies, deadhead any dying blooms throughout the growing season, which will encourage new growth and improve the appearance of your garden. To deadhead a bloom, follow the stalk of the flower all the way down to the base of the plant. Then, use small, lightweight shears to cut the stalk off right at the base. If you're cutting off multiple stalks, disinfect the shears in 1 part vinegar and 2 parts water in between cuts.
