Peace Lily Drooping: Dry Mix, Wet Roots or Repotting?
Updated · First published
Why is my Peace lily drooping?
A drooping peace lily is short of water in its leaves. Usually the mix is too dry, but wet, rotting roots, recent repotting, a pot packed with roots, fertilizer salts, and cold or hot spots cause the same droop.
What to do first
Feel the mix 5 cm (2 in) down before doing anything. Water a dry plant thoroughly; leave a wet one alone and check its roots; then look at the pot, the fertilizer, and where the plant sits.
A peace lily droops quickly and dramatically, which is frightening the first time. The good news is that the cause is usually simple. University of Maryland Extension’s watering guide notes that peace lilies wilt when they need water. It also warns that overwatered plants can wilt too. So the droop tells you something is wrong with water supply, not which way.
Use the checks below in order. Most plants are sorted by the first one.
Check 1: Is the mix dry?
Push a finger about 5 cm (2 in) into the mix, the depth Maryland Extension suggests. Lift the pot as well. Maryland notes that a pot with dry mix weighs much less than one with moist mix.
Clemson Extension’s peace lily factsheet says a plant left to dry out too much wilts, and its leaf edges turn yellow.
Dry mix: water thoroughly with room-temperature water, as Clemson advises, until water drains from the bottom. NC State Extension’s Spathiphyllum profile notes that watering from below works very well for peace lilies.
Check 2: Is the mix wet but the plant still drooping?
This points to the roots. Clemson warns that letting the plant sit in a saucer of water leads to root rot. University of Maryland Extension’s root rot page explains that rotting roots can make plants wilt even when the mix is moist. Rotted roots are brown to black and soft.
Maryland horticulturists answering an Ask Extension question suggest sliding the plant out to look. Black roots are rotting; white roots are healthy.
Wet mix: do not water. Empty the saucer and check the roots.
Check 3: Was it repotted or divided recently?
In the same Ask Extension answer, Maryland horticulturists diagnosed wilting after division as transplant shock. New soil, a new spot, and injured roots that cannot yet supply water all add up. Their advice was to avoid overwatering and wait for new growth. They also advised against stones in the pot bottom, which can stop water draining.
See our transplant shock guide.
Check 4: Are roots filling the pot?
Clemson’s houseplant disorders guide lists a pot-bound plant as a cause of wilting. With so many roots, there is not enough mix to hold water between waterings. A peace lily that droops again within days of a good watering may be in this state.
Clemson’s peace lily factsheet says to repot when roots grow through the drainage holes or circle on the surface. Move up only 2.5–5 cm (1–2 in) in pot size, because a much larger pot can stay too wet.
Check 5: Fertilizer salts and temperature
Clemson’s disorders guide also links wilting to too much fertilizer and salt build-up. NC State notes that over-fertilizing and salt build-up can burn leaf tips and roots. It recommends feeding at one-quarter strength and flushing the mix between feeds.
Then check the spot. NC State gives 20–29 °C (68–85 °F) by day, with no more than about 6 °C (10 °F) cooler at night. Clemson advises avoiding temperatures below 16 °C (60 °F). It warns that vents and drafts damage the plant and direct sun scorches the foliage.
Quick reference
| What you find | Likely cause | Next step |
|---|---|---|
| Light pot, dry mix, yellow leaf edges | Dry root ball | Water thoroughly |
| Heavy pot, wet mix, dark soft roots | Root rot | Stop watering, trim rot, repot |
| Moist mix, repotted recently | Transplant shock | Keep evenly moist, wait |
| Roots through drainage holes, dries fast | Pot-bound | Repot one size up |
| White crust on mix or pot rim, brown tips | Fertilizer salts | Flush the mix, feed less |
| Near a vent, cold window, or in sun | Temperature or light | Move it |
