Peace Lily
Spathiphyllum wallisii
Through the year 🗓️
☀️ Summer now
Its thirstiest season. Expect the dramatic wilt if you run late.
🍂 Fall
Fewer blooms as light fades; ease off the feeding.
❄️ Winter
Water less (never bone-dry) and keep it clear of drafts below 60 °F.
🌱 Spring
Divide crowded crowns; blooms return as the days brighten.
The details
Light & placement
- Light
- Medium–bright indirect; blooms need brightness, foliage tolerates shade
- Ideal PPFD
- 100–250 µmol·m⁻²·s⁻¹
- Grow-light distance
- 20–28 in below LED
Water & feed
- Watering method
- Keep lightly moist; water when the top inch dries. It dramatically wilts when thirsty and springs back within hours of watering.
- Fertilizer
- Balanced feed at ¼–½ strength, every 6 wks in spring–summer.
Home & habit
- Soil
- Rich, moisture-retentive but draining mix; pH 5.8–6.5
- Humidity
- High preferred (50%+); brown tips in dry air
- Temperature
- 65–80 °F
- Mature size
- 1–3 ft
- Repotting
- Every 1–2 yrs when roots crowd
- Propagation
- Division of crowns when repotting.

Common problems 🩺
The usual suspects when Peace Lily looks unhappy. Most houseplant trouble is watering or light, not disease — see all plant problems if you are not sure which plant is the culprit.
Dramatic full-plant droop
Likely cause
Thirsty. Peace lilies wilt theatrically, then recover fast once watered.
What to do
Water thoroughly. It should perk up within hours. If it droops while wet, check for rot.
Brown leaf tips
Likely cause
Tap-water minerals, low humidity, or overfeeding.
What to do
Switch to filtered water, raise humidity, and ease off fertilizer.
No flowers
Likely cause
Too little light — deep shade keeps it alive but bloomless.
What to do
Move it to brighter indirect light; blooms follow within a season or two.
Yellowing lower leaves
Likely cause
Natural aging, or overwatering if widespread.
What to do
Trim the odd old leaf. If many yellow at once, let the soil dry more between waterings.
