Propagating Peace Lilies

Ask The Expert: I read your article on Peace Lily  – (Spathiphyllum clevelandii) but didn’t see anything on how to propagate it.

Is it similar to a Hosta, (plantain )lily?

Thanks, JH

Yes it is basically the same process.  You create new peace lily plants by dividing them. Propagate by removing the peace lily from it’s container; then take a sharp knife and cut the plant from the roots to the top of the plant – this will ensure that each plants has an ample amount of roots. Take the divide pieces and follow the re-potting instructions.  The new container will need to be same size as original container.

Peace Lily Re-potting Instructions

Peace lilies (Spathiphyllum) should be re-potted when the root growth has overfilled the container. Use a humus rich potting soil to repot the peace lily. To help the roots to retain soil and prevent the root tearing, re-pot the plant when the soil is somewhat moist. For determining pot size follow this rule of thumb; use a pot that is 1½ times the size of the previous pot. When placing the peace lily in it’s new pot, keep the plant level the same as it was in the old pot (fill the pot so that the top of the root-ball is at the same level as before). After re-potting, water slightly to remove any air bubbles that might have occurred and wait a couple of weeks before fertilizing.
