Peace Lily / Spathiphyllum Plant

Lighting

• Ideally, keep peace lilies in a spot that gets bright, indirect light. An east-facing window is perfect, as the plant will be exposed to the bright morning sun. A north-facing window would also be a good choice for a peace lily.
• Keep peace lilies out of areas where they’ll get direct sunlight all day (such as in a south-facing window), as it may dry them out too much.

Watering

• When it comes to watering, consistency is key. Keep the soil lightly moist to the touch, but not overly saturated. Peace lilies can tolerate short periods of dry soil, but their leaves will start to develop brown tips if they don’t have enough water or humidity.
  • Tip: One nice thing about peace lilies is that they will tell you when they’re thirsty: the plant’s leaves start to droop. When the plant starts to look less “perky” than usual, test the soil with your finger. If it feels dry, it’s time to water again.
• Peace lilies are sensitive to chemicals commonly found in tap water, such as fluoride, which may cause brown leaf tips. Use filtered, room-temperature water, if possible.

Humidity

• Peace lilies enjoy high humidity. Misting their leaves or placing their pot atop a moistened tray of gravel can help to increase humidity around the plant.

Fertilizing

• Peace lilies are not heavy feeders, so fertilize only occasionally. To encourage spring and summer growth, fertilize every 6 weeks or so with a balanced houseplant fertilizer starting in late winter.

Temperature

• Peace lilies are a tropical plant, so keep them in temperatures above 60°F (16°C) and away from cold, drafty windows. They do best in temperatures upwards of 70°F (21°C).

Other Care

• The large leaves of peace lilies tend to collect a lot of dust in the home. Gently wipe them down with a wet paper towel occasionally; a thick layer of dust can inhibit photosynthesis.

How to Get Peace Lilies to Flower

• Most often, if no flowers are appearing, the plant is not getting enough light. Peace lilies are very tolerant of low light, but “low light” doesn’t mean no light! To encourage flowering, move the plant to a brighter location, where it will receive bright, indirect light for at least a few hours each day.
• Green flowers, weak-looking flowers, or a general lack of flowers can also be caused by improper fertilizing. In the case of green flowers, cut back on fertilizing, as the plant may be getting too much nitrogen. In the case of weak-looking flowers or a lack of flowers, try switching to a fertilizer made for flowering plants. This type of fertilizer will have a higher amount of phosphorous, which plants need for blooming.
