Watering: Peace lilies prefer consistently moist soil, but it's important not to overwater them. During summer, you might need to water more frequently due to higher temperatures, but always check the soil before watering. The top inch of soil should be dry before you water again. Use lukewarm water, as cold water can shock the plant.
Humidity: These plants thrive in high humidity. During dry summer months, you can increase humidity around the plant by misting the leaves regularly or placing a humidifier nearby. Alternatively, place the pot on a tray filled with pebbles and water, ensuring the bottom of the pot isn’t submerged in the water.
Temperature: Peace lilies prefer temperatures between 65°F and 80°F (18°C and 27°C). Avoid placing your plant near air conditioning vents or drafty windows, as cold drafts or excessive heat can stress the plant.
Light: Although peace lilies are known for tolerating low light, they do best in bright, indirect sunlight. During summer, avoid direct sunlight, which can scorch their leaves. A spot near a window with a sheer curtain would be ideal.
Fertilizing: In the growing season (spring and summer), feed your peace lily every 6 weeks with a balanced, water-soluble fertilizer diluted to half the recommended strength. Avoid over-fertilizing, which can harm the plant.
Pruning: Regularly remove yellow or brown leaves by cutting them at the base of the stem. This not only keeps the plant looking fresh but also encourages healthier growth and blooming.
Repotting: Summer is a good time to repot peace lilies if they have outgrown their pots or the soil needs refreshing. Choose a pot that’s slightly larger than the current one and use fresh, well-draining potting soil.
Pest Control: Keep an eye out for pests like spider mites, aphids, and mealybugs, which can be more active in summer. If you spot pests, treat the plant with a gentle insecticidal soap or neem oil solution.
