How to Divide Peace Lilies

By Stephanie Green ; Updated September 21, 2017

Peace lilies are a top pick for houseplants because they are so easy to grow and care for. There’s more good news about this plant. It’s just as easy to divide. Not only will dividing a peace lily literally afford you with a way to enjoy more of your plant, but it will help to improve the health of the plant once it outgrows its present container or pot.

Take the plant out of its pot or container. Remove any potting soil that is around the root ball by gently shaking the plant. Examine the root ball and the plant stalks that need to be split.

Use your hands and separate the stalks. Pull the stalks apart, taking care to keep a piece of root intact at the bottom of the stalk. Use a knife to cut the stalks apart if they will not easily come apart by hand. Place the plant on a flat surface and make a vertical cut through the root ball. Make individual plants from the separated stalks.

Prepare an individual pot for each new division. Use a small container as newly divided or small peace lilies grow best in a compact environment. Fill the pot half way with a mixture of potting soil and peat moss. Place the root ball in the center of the pot, on top of the potting medium. Cover the root ball and division with the potting medium. Water each division well.
