Overview

Peace lily plants are a common houseplant known for dark green foliage with leaves that reach up to one foot in length. The plant produces light green blossoms that turn white with age. The blossoms resemble those of a Calla Lily, are long lasting and stand out tall above the foliage. The main method of propagation is through root and crown division. Once repotted, the plants produce new root structures that grow off the divided crown.

Step 1

Water the plant well prior to making root divisions and repotting. This will plump the roots and crown to prevent tearing and speed new root growth.

Step 2

Remove the peace lily from the planting container and lay it on a flat surface. Gently remove dirt from the crown and examine the root structure to find new crown offshoots off the main crown sections. These are the sections removed for new plants.

Step 3

Cut and remove crown sections that have at least two leaves attached with a sharp knife. Try to make divisions that include roots attached to the crown.

Step 4

Fill a potting container with soil from the parent plant. Choose pots that are at least 3 inches in diameter and will adequately fit the divided crown. Place the crown into the pot so it is at the same depth as the original container. Add sterile potting soil if there is not enough parent soil available for all divisions and gently pack the soil around the root crown to eliminate air bubbles.

Step 5

Water the newly potted plants immediately after planting to stimulate root growth off the crown. Continue to water the plants to keep the soil moist. New root growth will occur in approximately one month.

Step 6

Fertilize the peace lily plant three months after making divisions and repotting to stimulate root growth. Use a 20-20-20 balanced fertilizer at 1/4 the dose. Fertilize every couple of months as peace lily plants do not require a large amount of fertilizer. Discontinue fertilizing if the tips of the leaves begin to turn brown and the plant is receiving adequate water.
