Peace Lily Care: Watering, Light, and Getting It to Flower
Priya Hollis · Oct 14, 2026 · 5 min read
Quick answer
A forgiving houseplant that tells you when it is thirsty — but often refuses to flower. Here is why.
Peace lilies (Spathiphyllum) are popular for their glossy leaves and white flowers. They cope with lower light than many flowering houseplants and wilt dramatically when dry, which makes them easy to read.
They are toxic to cats and dogs if chewed, so place them out of reach of pets.
1 Light
Bright, indirect light is ideal. Peace lilies survive in shade but flower less. Direct afternoon sun scorches the leaves, leaving brown patches.
2 Watering
Water when the top few centimetres of compost feel dry, and let excess drain away. A drooping plant usually perks up within hours of watering, but letting it collapse often stresses it and causes yellow leaves. Tap water high in chlorine or fluoride may cause brown tips; filtered or rainwater can help.
3 Getting it to flower
- ✓Move it to a brighter spot, out of direct sun
- ✓Feed with a balanced liquid fertiliser monthly in spring and summer
- ✓Avoid repotting into a much larger pot — slight root restriction helps
- ✓Be patient: young divisions may take a year to bloom
4 Common problems
Yellow lower leaves are often old leaves dying naturally, or overwatering. Green flowers are normal as blooms age. Cut spent flower stems at the base to keep the plant tidy.
