Peace Lily Pruning: Tips On How To Prune Peace Lily Plant

By: Liz Baessler

Peace lilies are excellent houseplants. They’re easy to care for, they do well in low light, and they’ve been proven by NASA to help purify the air around them. But what do you do when the flowers or even the leaves start to dry up and die? Should peace lilies be pruned? Keep reading to learn more about when and how to prune peace lily plants.

Peace Lily Pruning

Peace lilies are known for their big white bracts, the part we think of as a flower that is actually a modified white leaf surrounding a cluster of tiny flowers on a stalk. After this “flower” has bloomed for a while, it will naturally start to turn green and droop. This is normal, and it just means the flower is spent.

You can clean up the appearance of the plant by deadheading. Peace lilies produce their flowers on stalks that grow up from the base of the plant. Once a stalk has made one flower, it won’t make any more – after the flower fades, the stalk will eventually brown and die as well. Peace lily pruning should be done at the base of the plant. Cut the stalk off as close to the bottom as you can. This will make room for new stalks to emerge.

Pruning a peace lily isn’t limited to the flower stalks. Sometimes leaves yellow and start to shrivel up. This may be due to under watering or too much light, but it can also happen just because of old age. If any of your leaves are turning color or drying out, just cut the offending leaves away at their base. Always disinfect your shears between each cut to prevent the spread of disease.

That’s all there is to pruning peace lilies. Nothing too complicated, and a very good way to keep your plants looking healthy and happy.

When to Prune Plants

#1. When You See Dead, Diseased, or Tangled Branches

This is a very general and obvious rule that when you see a dead or diseased branch, it must be cut off. This way, the rest of your plant will grow big and healthy. When you see branches crossing or rubbing each other, you should also prune one of them to ensure healthy growth.

#2. Late Spring

Flowers such as forsythia, lilacs, or rhododendrons should be pruned in late spring. Cut these plants back right after they’ve finished blooming to keep their shape. If you wait and prune too late, you may risk cutting off flower buds.

#3. Summer Bloomers

Shrubs and trees that bloom in the summer should be pruned in the winter while they are dormant. Alternatively, you can also prune in early spring before new growth appears.

#4. Showy Shrubs

Shrubs and trees with big or show-stopping foliage such as burning bush or barberry can be pruned almost any time except for in late fall. This is because new growth won’t have time to harden properly over the winter months.

#5. Garden Hedges

Cut back your hedges frequently during the early growing season. Pruning should be stopped about 6 weeks before the first frost.

#6. Roses

Roses that bloom annually should be treated just like other spring-blooming shrubs. Prune these right after the flowers face, and prune other varieties that bloom repeatedly in early spring.

#7. Fruit Trees

Fruit trees are a little more tricky because their grow time is so long and there are many different varieties. Apple trees, for example should be pruned in later winter for a vigorous growth. A cherry tree, by comparison, should be pruned in summer. Never prune more than 25% in a year, and always make sure to cut off any dead, diseased, or tangled branches.

So now that you know when to prune your plants, it’s time to roll up your sleeves and get to planting!

How to Grow Peace Lily

Follow this growing advice and, with some experimentation, your plant should bring beauty to your house for years to come.


Peace lilies are a good choice for low-light spaces because they can thrive in shade or partial shade. They also tolerate fluorescent lights, so if you need a plant friend to liven up your desk at the office, peace lily is a good option.

Peace lilies like a consistent temperature from 65 to 80 degrees Fahrenheit. Protect your plant from drafts and cold or drastic changes in temperature. So, maybe don’t place yours by a door that opens out into the cold winter air.


In spring and summer, use an organic houseplant fertilizer to help your plant bloom. Keep in mind that peace lilies are sensitive to chemical fertilizers, so organic options are best.


Peace lilies like to be watered a lot at once, but also need a chance to dry out afterward. The plant will droop a bit when thirsty, telling you when it needs a drink. If you pay attention to when it usually starts to sag, you can plan to water one day before it generally happens. Watering about once a week and spritzing leaves with water throughout the summer will help keep your peace lily hydrated. If your plant seems to completely droop, don’t give up — water and spritz and give it a chance to revive. If your water is chlorine-heavy, let a container of water stand overnight before watering the plant.


Peace lilies are susceptible to root rot, so it’s very important to make sure the plant has a chance to dry out between waterings and that the container it lives in drains well. Choose a container with drainage holes and place a saucer under to catch water that drains out. If your plant starts to wilt, check the roots to make sure they are firm and light-colored rather than soggy. If they’re soggy, you’re overwatering or the soil isn’t able to drain.

How To Prune A Peace Lily: The Proper Way to Prune A Peace Lily

Peace lilies actually require little to no pruning to stay healthy and strong. They do not produce many blooms, and the bud that is produced tends to have one bract or flowerlike structure that looks like a white petal. Since there aren’t many blooms, you don’t need to trim a bunch of deceased buds at the end of the growing season.

Individuals who do want to prune should cut the bract once it has died for the season. Instead of cutting directly underneath the flower, prune lower on the stem. This ensures there is more room for new stems to grow once the right season comes again.

Besides the flower stalks, it might be necessary to prune the leaves. Normally, they should be allowed to grow luxurious and green. However, sometimes they start to fade and turn yellow, especially if there has been a water shortage or too much sunlight. When this happens, cut away the offending leaves at their base, not in the center of the leaf.

After you remove each leaf, disinfect your shears or scissors. This eliminates the possibility of spreading disease that could have caused the leaves to yellow in the first place.


Deadheading is a common element of pruning, including for peace lilies. This process is when individuals cut away dead flowers to make room for fresh ones. It is a crucial process for many plants, but especially annuals and perennials that will continue to flower throughout the growing season.

If you want to deadhead a peace lily, focus on cutting away the bud just underneath the bloom itself. This should be done before the first set of healthy leaves. Because the peace lily tends to only produce one bract, consider cutting down all the way to the bottom of the stem before it reaches the leaves. This will facilitate future growth.

How To Prune A Peace Lily: Avoid Leaving Trimmings

Whether or not a peace lily is kept indoors will depend on the individual, but it’s important not to leave any trimmings behind. According to the American Society for the Prevention of Cruelty to Animals (ASPCA), peace lilies are toxic to cats and dogs. Leaves, petals, stems, and other elements should not be left behind after trimming, as they might be consumed by pets or stray animals looking for a snack.

If you do choose to keep and prune a peace lily indoors, try to keep it out of reach of the household animals. Ensuring it doesn’t get chewed on can facilitate growth just as much as pruning!

What to Use

Although many novice gardeners try to use regular kitchen scissors, this is a bad idea for pruning peace lilies. Instead of using these scissors, which are full of bacteria and often don’t have sharp edges, consider using professional pruning shears instead.

Hand pruners are the best type to use because they are small and scissor-like. Using a larger set would be overkill since peace lilies do not grow very large. To find a good pair of hand pruners, consider going to a dedicated gardening store. They will have a wide variety.

If you need to sanitize the shears after use, use a basic alcohol solution. It will kill any bacteria and leave the blades ready for future use. Allow the solution and shears to dry before attempting to prune again. Alcohol can kill flowers and other plants.
