Dividing a Mature Peace Lily: Propagation and Light Needs

Your 5-year-old peace lily in a root-filled 10-inch pot is ready for division—a great way to rejuvenate and multiply.

Division Steps

1. Remove plant, gently separate root ball into 2–3 sections.
2. Each section needs roots and leaves. Don't tear main roots.
3. Pot each in container 2 inches larger than its root mass.
4. Use fresh, well-draining mix. Water well.

Light Requirements

Bright indirect light. Direct sun burns leaves. More light = more flowers. Sheer curtain at south/west window works.

Post-Division Care

• Keep evenly moist, not soggy.
• Expect temporary droop—recovers in days.
• Fertilize at half strength after new growth appears.

Division every few years keeps peace lilies vigorous and blooming.
