Hi. I've read online that you can divide your peace lily if you don't want it growing too large. I'm considering on doing that and was wondering if anyone has had success with dividing their peace lily? The thought of cutting up their roots scares me.

Has it totally filled its current pot?
Don't rush to do it. They don't like to be ripped apart, seems to me. I do have a (non-gardener) friend who has divided hers alot. May be best to just cut the rootball without disturbing the roots any more than necessary. Keep well watered after, making sure the original root ball is absorbing water. Sometimes the new soil absorbs the water more easily,leaving the roots getting dry inside the thick original part.

I have divided them by ripping apart, but then read (WillC?) that they don't like this. Indeed, some take a long time to recover from my ripping and repotting.

There are three options:

1. Keep it in its pot and leave it sitting in water because the roots will need a constant supply of water. Trim off some of the outside leaves. This will maintain it in its existing pot without disturbing the roots.

2. Prune the roots by using a sharp, sturdy knife and slicing off approximately a half inch of rootball all around the perimeter and bottom of the plant. Then put it back into its pot and fill in the space with fresh potting mix.

3. You can divide your Peace Lily if it is very healthy and rootbound. Use a long, sturdy, sharp knife to slice straight down through the diameter of the plant and rootball. Just cut it in half. Of course, you will damage some of the roots, but fewer than if you try to pull the rootball apart with your hands. Each half will need its own separate pot.

Not at the moment, but when it does I would like to divide it to keep one in the bathroom.


Thanks for the advices!
