The Best Way to Divide a Peace Lily
- 1). Water the plant well and allow it to drain completely a day before dividing. Never allow a peace lily to sit in water; tilt the pot to help drain water if necessary.
- 2). Tap the pot to drop the plant's root ball out of the pot on its side. Pick the root ball up and remove as much dirt as possible. The plant will splay apart into two or more bunches of crowns.
- 3). Pull the divisions apart. If necessary, cut through the rhizome with a sharp knife. Depending on the size of the plant, divisions may have a few crowns or a dozen or more. Each crown should have at least three leaves rising from it.
- 4). Prepare new pots while waiting for cuts made on the rhizome to dry. Use clean pots that have drainage holes on the bottom. Fill them partially with new, light potting soil that will drain well.
- 5). Set divisions in pots, one at a time, and spread the roots over the soil in the pot. Fill the remaining space and tamp the soil, positioning the crowns just under soil level. Leave 1 to 2 inches of space between the rim of the pot and soil level.
- 6). Water well and put divisions in bright, but not direct, light away from drafts. Water plants when leaves begin to droop. Wait a month to fertilize plants.
