How Often To Water A Peace Lily?
Water a peace lily about once a week, when the top inch of soil is dry. Learn why it droops so dramatically and whether distilled water helps.
Water a peace lily about once a week in spring and summer, and every 1 to 2 weeks in winter. Wait until the top inch of soil feels dry, then water until it drains. A sudden droop usually means it is thirsty, and it should perk up within a few hours of a drink.
A starting point, not a rule. Check the soil before each watering and stretch the gap in cool, cloudy weather.

The peace lily is the most dramatic plant in the house. Miss a watering and it collapses like it has given up, then stands tall again an hour after a drink.
In the wild, peace lilies grow on the floor of tropical rainforests, in rich soil that stays lightly moist. They like steady water but not wet feet. Your job is to water when the top inch dries, and let the droop be your backup alarm, not your schedule.
Peace lily watering schedule
| Conditions | How often |
|---|---|
| Bright indirect light, summer | Every 5 to 7 days |
| Medium light, spring or fall | About once a week |
| Low light | Every 1 to 2 weeks |
| Winter, any light | Every 1 to 2 weeks |
Small pots and warm rooms dry out faster. A big plant in a large pot can often go longer.
How to tell when a peace lily needs water
Push a finger about 1 inch into the soil. If it feels dry, water today. If it feels cool and damp, wait a few days.
The leaves send the clearest signal. Early thirst makes them look slightly soft and dull. Real thirst makes the whole plant flop over. It recovers well, but letting it collapse again and again stresses the plant and browns the leaf tips.
How to water a peace lily
- Water slowly over the whole pot. Wet all the soil until water runs from the drainage hole.
- Empty the saucer. Pour out extra water after 15 minutes so roots do not sit in it.
- Use room temperature water. Cold water can shock the roots of tropical plants.
- Wipe the leaves now and then. Dust blocks light, and clean leaves stay greener.
Signs of overwatering and underwatering
Too much water
- Yellow leaves, often lower ones first
- Drooping even though the soil is wet
- Black, mushy roots and stem base
- Fungus gnats around the pot
Too little water
- Whole plant collapses
- Brown, crispy leaf tips and edges
- Soil pulling away from the pot edge
- Flowers that brown early
Tap water, filtered or distilled
Peace lilies are a little sensitive to the chlorine, fluoride and salts in some tap water. Over time, this can show up as brown leaf tips.
Distilled water, filtered water or rainwater all work well, but you do not need them for a healthy plant. A simple fix is to fill your watering can and let it sit out overnight so some chlorine escapes. Flush the pot with plenty of water every few months to wash out salt buildup.
If you love easy plants, the pothos follows a similar rhythm. The snake plant needs even less.
Peace Lily watering FAQ
Is distilled water good for peace lilies?
Yes, it works well and can reduce brown tips. It is not required, though. Tap water left out overnight is fine for most homes.
Should I mist my peace lily?
It can help in very dry rooms, but it is not essential. A pebble tray or grouping plants together raises humidity more steadily.
Can a peace lily recover from drooping?
Yes. A thirsty peace lily usually perks up within a few hours of watering. If the soil was already wet, the problem is too much water instead.
