Tending to Houseplants: Caring for a Peace Lily (Spathiphyllum)
Peace lilies, scientifically known as Spathiphyllum, are popular houseplants known for their lily-like symbolism, including peace, love, compassion, healing, and hope. These tough plants require little fuss as long as they get a few basic needs met.
Ideal Care Requirements for Peace Lilies
Light
Peace lilies thrive in bright, indirect sunlight but can tolerate low-light conditions. Avoid direct sun exposure, which can scorch leaves.
Watering
Keep the soil consistently moist but not soggy. Water when the top inch of soil feels dry, typically about once a week. Use filtered or rainwater if possible, avoiding fluoride and chlorine. Leaves will droop when the plant needs water but recover quickly after watering.
Soil
Use a well-draining potting mix composed of peat moss, cocopeat or peat, and perlite to promote healthy root growth and prevent waterlogging. Ensure pots have drainage holes.
Temperature
The ideal temperature range is 65-80°F (18-27°C). Protect the plant from cold drafts and sudden temperature changes.
Humidity
Peace Lilies prefer moderate to high humidity (above 50%). Misting occasionally or placing near a humidifier helps maintain humidity, which supports year-round blooming.
Additional Recommendations
- Light fertilization every 6–8 weeks during the growing season (spring through early fall) with diluted balanced liquid fertilizer.
- Repotting every 1–2 years to refresh soil and accommodate growth.
Common Issues and Solutions
- Green flowers on peace lilies could indicate an excess of nitrogen, possibly caused by too much fertilizer or the wrong type of fertilizer.
- Curling leaves may indicate too much water or too little water. Improper conditions can cause peace lilies to curl their leaves.
Interesting Facts
- The peace lily, specifically Spathiphyllum wallisii, resembles a classic lily with glossy green leaves and white flowers.
- Peace lilies can grow up to 16 inches tall. Some varietals have leaves up to 9 inches wide, while others grow leaves up to 20 inches long.
- Peace lilies can flower twice a year, with blossoms lasting a month or longer.
- Peace lilies are toxic to dogs and cats.
- Peace lilies grow in nature on the floor of rainforests in Central and South America.
- Propagating peace lilies can be done through division, a process that involves removing the plant from the pot, cutting away small stems, dividing the roots, preparing a new pot for each division, replanting in fresh, moist soil, and keeping the soil moist until new growth appears.
In summary, keep Peace Lilies in bright indirect light, maintain moist but well-draining soil, provide warmth and humidity, and monitor watering by checking soil dryness and leaf drooping for best growth and flowering. These tough plants are a great addition to any home, offering beautiful symbolism and minimal care requirements.
Nurturing a Peace Lily properly requires maintaining the plant in a bright, indirect light environment, perfect for both home interiors and garden settings. Adequate air humidity, mostly above 50%, contributes significantly to its flourishing and consistent blooming.
