Indoor peace lilies, also known as Spathiphyllum, are a popular houseplant due to their beautiful white flowers and ability to purify the air in your home. These plants are relatively easy to care for, but there are a few key things to keep in mind to ensure they thrive.


First and foremost, peace lilies prefer bright indirect light. They can tolerate low light, but they will not bloom as often and their leaves may become yellow. A north or east facing window is ideal, but you can also place them near a south or west facing window with sheer curtains to filter the light.


When it comes to watering a peace lily, they are very sensitive to over-watering. The soil should be kept consistently moist, but not soggy. We highly recommend using a plant moisture meter to check the moisture level, rather than relying on a set watering schedule. If the meter goes to dry and the soil feels dry to the touch, it's time to water. If the soil is still damp, wait a few more days before checking again.

Temperature and Humidity

Peace lilies prefer temperatures between 65-80°F (18-27°C). They can tolerate temperatures as low as 55°F (13°C), but temperatures below that can cause damage to the leaves and flowers. Avoid placing your peace lily near drafty windows or doors, as this can cause the temperature to fluctuate and stress the plant.
In terms of humidity, peace lilies prefer a humidity level of around 60-70%. If your home is on the dry side, you can place a tray of water near the plant or use a humidifier to increase the humidity. Or you can place rocks in the saucer and keep that filled with water every few days. The roots will appreciate being close to that humidity.


Peace lilies also benefit from regular fertilization. A balanced, water-soluble fertilizer can be used every 4-6 weeks during the growing season (spring and summer). Be sure to follow the manufacturer's instructions for application.


Wondering why your peace lily isn't flowering? Here are some potential reasons why:

  • Insufficient light: Peace lilies require bright indirect light to flower. If the plant is not receiving enough light, it may not produce flowers.
  • Improper watering: Peace lilies prefer consistently moist soil, but overwatering can lead to root rot and prevent the plant from flowering. However, under-watering can cause the leaves to droop and prevent the plant from producing blooms.
  • Nutrient deficiencies: Peace lilies require regular fertilization to thrive, and a lack of essential nutrients like nitrogen, phosphorus, and potassium can prevent the plant from flowering.
  • Temperature fluctuations: Peace lilies are sensitive to temperature changes, and extreme heat or cold can cause stress that prevents flowering.
  • Pests or disease: Insects like spider mites or fungal diseases can damage a peace lily and prevent it from flowering. These pests can be controlled with a gentle insecticidal soap or neem oil.
  • Age of the plant: Peace lilies typically flower once per year, and younger plants may take longer to reach maturity and produce blooms.
  • Lack of humidity: Peace lilies prefer high humidity, and dry air can prevent the plant from flowering.
  • Repotting stress: If a peace lily is recently repotted, it may take some time for the plant to adjust to its new environment and resume flowering.

Don't be afraid to give your peace lily a little extra care and attention. Trim off any brown or yellow leaves, and be sure to deadhead the flowers as they fade to encourage new blooms. With proper care, your peace lily will not only look beautiful, but will also help to purify the air in your home.
