How to Care for a Peace Lily
One of the easiest houseplants to keep alive — peace lilies thrive in low light, tell you when they're thirsty, and reward consistent care with beautiful white blooms.
Peace Lily at a Glance
Everything you need to know, in four numbers.
Complete Peace Lily Care
Peace lilies (Spathiphyllum) are forgiving plants that adapt to most indoor environments. Here's everything you need to keep yours healthy and blooming.
Light
Bright indirect light is ideal, but peace lilies genuinely thrive in low-light rooms. Never place in direct sun — even an hour of afternoon sun will scorch the leaves and cause yellowing.
Watering
Let the top inch of soil dry before watering. Peace lilies droop when thirsty and bounce back within hours of watering. Always use a pot with drainage — sitting in water causes root rot quickly.
Humidity
Peace lilies prefer 40–60% humidity. Kitchens and bathrooms work well. Avoid placing near heating vents or air conditioners — dry air causes brown leaf tips. A pebble tray with water is an easy fix.
Fertilizing
Feed monthly with a balanced liquid fertilizer (10-10-10) diluted to half strength during spring and summer. Skip fertilizer in autumn and winter when growth slows. Over-fertilizing causes brown leaf tips.
Soil & Potting
Use a well-draining all-purpose potting mix. Repot every 1–2 years in spring, moving up one pot size (1–2 inches wider). Cramped roots cause the plant to dry out faster and can limit growth.
Temperature
Peace lilies prefer 65–85°F (18–29°C). They're sensitive to cold drafts and temperatures below 55°F (13°C) — keep away from cold windows in winter. A consistent room temperature is all they need.
Peace Lily Stress Signals
Your peace lily communicates clearly. Here's what each symptom means and how to fix it. If the symptoms do not match, use the plant disease identifier with a clear photo.
Yellow leaves
Cause: Overwatering or too much direct sun
Fix: Let soil dry out more between waterings. Move to bright indirect light. Check for root rot — mushy roots need to be trimmed and the plant repotted.
Drooping leaves
Cause: Underwatering or root bound
Fix: Water thoroughly and wait a few hours — droopy leaves from thirst bounce back quickly. If the soil is moist and it's still drooping, check whether roots are circling the pot and repot if needed.
Brown leaf tips
Cause: Low humidity or fluoride sensitivity
Fix: Move away from heating vents. Use filtered or distilled water, as peace lilies are sensitive to fluoride and chlorine in tap water. Raise humidity with a pebble tray or humidifier.

Peace Lily Care FAQ
How often should I water a peace lily?
Water your peace lily every 1–2 weeks, allowing the top inch of soil to dry out between waterings. Peace lilies will visibly droop slightly when they need water — use this as your cue. In winter, water less frequently as growth slows.
Can peace lilies grow in low light?
Yes. Peace lilies are one of the best houseplants for low light. They thrive in bright indirect light but tolerate shadier spots well. Avoid direct sunlight — it scorches the leaves and turns them yellow. A north or east-facing window is ideal.
Why are my peace lily leaves turning yellow?
Yellow leaves on a peace lily usually mean overwatering or too much direct sunlight. Check the soil — if it's consistently wet, let it dry out more between waterings and ensure the pot has drainage holes. If the plant is in direct sun, move it to bright indirect light.
Why is my peace lily drooping?
Drooping is almost always a sign of underwatering. Peace lilies droop dramatically when thirsty but recover quickly after watering — usually within a few hours. If the soil is moist and the plant is still drooping, it may be root bound and need repotting.
Are peace lilies toxic to cats and dogs?
Yes. The ASPCA lists peace lilies as toxic to cats and dogs — the toxic principle is insoluble calcium oxalates, which cause oral irritation, drooling, vomiting, and difficulty swallowing if ingested. Keep peace lilies out of reach of pets and small children.
When do peace lilies bloom?
Peace lilies have no fixed bloom season and flower freely under the right conditions, per NC State Extension — most owners see the heaviest flush in spring, sometimes again in autumn. The white spathes (often mistaken for flowers) last several weeks. To encourage blooming, give the plant bright indirect light and feed with a balanced liquid fertilizer monthly during spring and summer.
Should I mist my peace lily?
Misting can help temporarily raise humidity around your peace lily, but it's not a substitute for consistent ambient humidity. Peace lilies prefer 40–60% humidity. Better options include a pebble tray with water, grouping plants together, or placing the plant in a naturally humid room like a bathroom or kitchen.
How do I know when to repot my peace lily?
Repot your peace lily when roots start growing out of the drainage holes, the plant dries out very quickly after watering, or growth has slowed significantly. Repot every 1–2 years in spring, choosing a pot only 1–2 inches larger than the current one. Use a well-draining potting mix.
