Why Pruning is Essential for Peace Lilies
Pruning is more than simply making your plant look good. Its health is affected by how it’s pruned (or how it isn’t).
When you remove old, damaged or unnecessary parts of your peace lily what you’re doing is letting it stop wasting energy on growing or trying to revive those parts. Instead it can focus that energy into new growth and flowers.
If that isn’t enough to convince you these are the main reasons to prune your peace lily:
- Encourage new growth: Spent flowers and dead leaves use up resources and energy the plant needs. When you remove them it helps your plant to grow better and be healthier.
- Improve air circulation: When your peace lily is overcrowded it can result in more pests and diseases.
- Maintain a tidy appearance: Its less important but when you prune your peace lily it stays fresh and looks good.
What You’ll Need
The Basics
Before you get started you’ll need some tools:
- Sharp scissors or shears: if your tools are dull then they can tear the plant when you cut and cause damage.
- Disinfectant: Something like rubbing alcohol or bleach is important. All you have to do is wipe the plant and it will
stop the spread of diseases to any of your other plants. - Gloves: Peace lily sap can irritate the skin so use gloves.
Optional
- A spray bottle can be used to clean the plant before pruning.
- A cloth to wipe the leaves.
- A small brush or tweezers will help to remove any of the dirt or cuttings.
When Should You Prune a Peace Lily?
You can prune your peace lily at any time of the year. However there are some times when it’s better to do it:
- After the blooms have faded: Spent flowers are something you are obviously going to want to get rid of.
- As leaves yellow or brown: Yellow or brown leaves are a clear sign of either stress or aging and will want to be removed.
- During a regular care routine: when you water or dust your peace lily it’s a good time to check for any damaged leaves or flowers.
Step-by-Step Guide to Pruning a Peace Lily
1. Inspect the Plant
You should begin by looking at your peace lily closely and checking for:
- Wilted or brown flowers.
- Yellow or drooping leaves.
- Healthy leaves that have brown tips.
- Damaged stems or too overcrowded leaves.

2. Clean Your Tools
Disinfect your scissors or shears before and after you use. You don’t have to do anything special, just quickly wipe them with rubbing alcohol. This is important to stop any bacteria or fungi from getting spread to your peace Lily.
3. Remove Spent Blooms
The flowers on your peace lily will fade and look green or brown (maybe a mix
If the two) as they get older. If you want to remove them:
- Follow the flower stalk (not the leaf!) down to its base.
- Use your scissors or shears to cut as close to the soil as possible.
- Try not to disturb the leaves close to where you’re cutting.
4. Trim Damaged or Yellow Leaves
Yellow leaves should be expected on a peace lily. They are all part of its normal life cycle.
But people often want to remove them as they don’t look as good. So if you want to:
- Entire leaf yellow: Cut it off at the base near the soil.
- Only the tip has turned brown: Trim just the brown part. Follow the curve of e leaf.
5. Address Overcrowding
If your peace lily is starting to looking a bit too dense then you might want to thin it out. Do so by removing the smaller, weaker stems as it will help the air to flow properly around the plant and make pests less likely.

Water Carefully
Pruning can slightly stress your peace lily. To help it recover give it a small water after you’re finished pruning.
