Introduction

Spathiphyllum, more commonly known as the Peace Lily, is an evergreen flowering species native to tropical regions of Latin America. Its lush green foliage and creamy white blooms make it a popular houseplant choice.

The Peace Lily thrives in indirect light and moist soil. For its best health, temperatures should remain between 18-26°C with average humidity levels. It is an excellent plant for purifying air indoors by removing common pollutants like formaldehyde, benzene and trichloroethylene from the environment. Moreover, its stunning blooms can last up to 8 weeks - making it a reliable source of year-round color despite minimal care requirements.

Peace Lily Care

Peace Lilies are relatively easy to care for and adapt well to low light conditions. They thrive best in rich, well-draining soil and prefer a consistent watering schedule that keeps their soil lightly moist. Temperature-wise, they favor typical indoor conditions, between 65 and 80 degrees Fahrenheit, and high humidity. Regular feeding during the growing season with a balanced houseplant fertilizer will support their growth and flowering.

Light

Peace Lilies prefer bright, indirect light, but are known to tolerate low light conditions well, making them suitable for spaces that do not get a lot of natural sunlight. However, to ensure robust growth and regular blooms, place them in a spot that receives filtered light. Prolonged exposure to direct sunlight can scorch their leaves.

Soil

For Peace Lilies, a well-draining soil rich in organic matter is ideal. You can use a high-quality all-purpose indoor plant potting mix. The soil should retain some moisture but drain well to prevent water-logging, which can lead to root rot.

Water

Peace Lilies prefer their soil to be consistently moist, but not soggy. Water them thoroughly when the top inch of the soil feels dry to the touch, or when you notice a slight drooping in the foliage - a clear signal the plant needs water. Overwatering can lead to yellow leaves and root rot, so make sure your pot drains well and never let the plant sit in standing water.

Temperature and Humidity

These plants prefer warmer temperatures, ideally between 65 and 80 degrees Fahrenheit. They do not tolerate cold drafts or freezing temperatures. Peace Lilies also appreciate high humidity. You can maintain high humidity levels by misting the plant regularly, placing it on a pebble tray with water, or using a humidifier.

Fertilizer

Feed your Peace Lily with a balanced (20-20-20) houseplant fertilizer every 1-2 months during the growing season (spring and summer) to support its growth and flowering. Follow the instructions on the fertilizer packaging for dosage recommendations. Remember to reduce or stop fertilizing during the plant's dormant period in the winter.
