Peace Lily: repeated severe drought cycling — what does it look like?

Wilts more often and recovers less completely. Lower leaves yellow permanently. Brown crispy tips throughout. Water before the collapse, not because of it. Damage already done is permanent but the plant usually recovers if caught.

Peace Lily: root rot — what does it look like?

Wilting that does NOT recover after watering — the key diagnostic. Soil already wet when it wilts. A wilting peace lily in wet soil is rotting, not thirsty. This distinction decides whether it lives.

Peace Lily: direct sun scorch — what does it look like?

Bleached pale patches or dry brown burns on leaves facing a window. Understory plant. Direct midday sun burns it. Move back from the glass.

What went wrong

Peace Lily

Spathiphyllum

The only plant that tells you when it is thirsty. People still miss it.

The peace lily is unusually communicative: it wilts theatrically when dry and recovers within hours of watering. This is a genuine gift and it is also the mechanism of its death, because owners learn to use the dramatic collapse as their watering cue.

Repeated wilt-and-revive cycles progressively kill root hairs. The plant recovers a little less each time, and eventually a collapse comes that watering does not fix.

Usually one of these

The question you actually have

Dead or dormant?

Water thoroughly and wait four hours. A thirsty peace lily will be visibly upright again; a rotting one will not move at all. If nothing changes overnight, unpot it — a peace lily that fails to respond to water has a root problem, and the only question is whether any firm root remains to divide and save.
