Step 2: Increase Humidity Around the Plant
Low humidity is the biggest enemy of peace lilies in winter.
Simple Ways to Boost Humidity
1. Use a Humidity Tray
- Place pebbles in a shallow tray
- Add water just below the top of the stones
- Set the pot on the stones (not in the water)
As water evaporates, it adds moisture to the air.
2. Group Plants Together
Plants release moisture naturally. Grouping them creates a small humid micro-climate.
3. Use a Humidifier
A cool-mist humidifier is one of the most effective solutions, especially in heated homes.
4. Light Misting (With Caution)
Misting can help temporarily, but it’s not a long-term solution on its own.
Step 3: Move the Plant Away From Heat Sources
Peace lilies are sensitive to temperature extremes.
Keep Your Plant Away From:
- Radiators
- Heating vents
- Fireplaces
- Drafty windows
Hot, dry air blowing directly on the plant will quickly dry out leaves and soil.
Ideal Temperature Range
Peace lilies prefer:
- 65–80°F (18–27°C)
- Stable temperatures with no sudden changes
Step 4: Adjust Winter Watering Habits
Many people either overwater or underwater peace lilies in winter.
Winter Watering Tips
- Water less frequently than in summer
- Always check soil before watering
- Avoid letting the plant sit in standing water
Dry air may trick you into watering too often, so balance is key.
Step 5: Trim Damaged Leaves and Tips
Brown tips and yellow leaves won’t turn green again, but trimming them helps the plant redirect energy.
How to Prune Properly
- Use clean, sharp scissors
- Cut brown tips at an angle
- Remove yellow leaves at the base
This improves appearance and supports healthier growth.
Step 6: Check Light Conditions
Winter light is weaker and shorter, which can stress peace lilies further.
Best Winter Light
- Bright, indirect light
- Near a window with sheer curtains
- Avoid direct sunlight
Too little light can reduce flowering, while too much can scorch leaves.
Step 7: Avoid Fertilizing During Stress
When a peace lily is stressed from dry air, fertilizing can do more harm than good.
Fertilizer Rules in Winter
- Pause fertilizing during winter months
- Resume in spring when growth increases
- Use diluted fertilizer when restarting
Plants in recovery need stability, not extra nutrients.
