Peace Lilies prefer comfortable indoor temperatures, ideally around 18–27°C. Protect them from cold drafts, sudden temperature changes, air-conditioning vents, and direct blasts of hot air from heaters. A stable, warm location helps your plant maintain healthy foliage throughout the year.

As a tropical plant, the Peace Lily appreciates moderate to high humidity. Average household humidity is often acceptable, but very dry air can contribute to brown leaf edges.

Increase humidity with a humidifier or group your plant with other houseplants. Misting provides only a temporary effect and is not a substitute for suitable humidity and watering.

Feed your Peace Lily with a balanced liquid houseplant fertilizer diluted according to the product label during active growth in spring and summer. A light feeding schedule is usually sufficient; too much fertilizer can damage roots and cause brown leaf tips.

Reduce or pause feeding during slower winter growth. If the plant has recently been repotted in fresh, fertilized potting mix, wait before adding more fertilizer.
