Keep the compost damp but not saturated and water when the surface or upper few centimeters have dried. A dramatic droop can be an observable sign that the plant may need water, not a universal calendar interval.
How to water Spathiphyllum wallisii
Water a peace lily when the surface or upper few centimeters have dried, then wet the root ball and let it drain. The plant should not sit in standing water or stay saturated.

When to water
Reduce watering slightly in winter when growth slows, then return toward the active-growth pattern as light and growth increase. This is a directional change, not a fixed winter schedule for every home.
How to water thoroughly
- Water thoroughly enough to wet the root ball, allow the container to drain freely and pour away water from the saucer or outer pot. Room-temperature or suitable rain or filtered water may be appropriate. No fixed volume is established.
- Do not leave the peace lily in standing water because roots can rot when compost stays wet for long periods. The exact RHS profile describes a damp but draining container balance. Avoiding saturation does not mean allowing complete dry-out.
Signs of too much or too little water
Drooping can follow a dry root ball, while yellowing, brown tips or root decline can also follow overwatering, low humidity, direct sun, salts or another stress. Inspect moisture and roots before changing the routine.
