Requirements for Growing Peace Lily
The peace lily is native to the tropical climate where it grows under the canopy of trees in warm and humid weather. Any spot that replicates those conditions is best for its growth. As it requires a shady spot and constant temperature, it does best indoors as a houseplant. Somewhere where it can receive bright indirect sunlight, a few hours of morning sunlight is beneficial.

Keep peace lily and other houseplants that prefer humid surroundings away from air vents of your AC and heating units. Keeping this plant close to a dehumidifier is also a NO, NO!
Peace lily prefers evenly moist soil when grown outdoors. You can keep the soil slightly moist all the time of your indoor peace lily, but this might lead to overwatering if you don’t have a green thumb.
Follow the “better safe than sorry” strategy and water only when the topsoil is a bit dry and deeply, whenever you do until it starts to drain out from the bottom. Watering once in every 5-7 days is enough to fulfill the plant’s need.
- If this indoor plant requires water every 2-3 days, it must be root bound and needs repotting.
- If you’re very new to growing indoor plants, wait for the plant to droop a little before watering again so that you’ll know it definitely requires water.

The diameter of the pot ranging from 8 to 10 inches is enough to hold a mature peace lily plant. Initially, you can plant it in a smaller container which is 6-8 inches wide, and deep similarly or more. If you’re growing two-three of these plants together, you’ll need a large 12 inches pot.
When the plant outgrows the current pot, move it to a new container that is a couple of inches large in the diameter. If you don’t want to change the pot, take out the plant and divide the rootball and repot the original plant. This way, you’ll have new peace lily plants, and mother plant will have more space to spread the roots.
Don’t fret when it comes to the material–clay, ceramic, metal, wood and plastic, all are suitable. To avoid waterlogging, providing drainage holes at the bottom is most important.
Growing under the canopy of trees in the rainforest in their natural habitat, peace lilies have an abundance of dead and decaying matter in the growing medium. That’s what you’ll need to keep in mind when choosing the potting mix. Presence of sand, perlite, composted bark, peat, well-rotted compost, or any other organic matter makes the potting medium perfect. Also, it should be light and well-draining. You can learn how to make homemade potting mix here or buy the commercial one.
Peace Lily Care
Maintaining the Humidity
As you know, peace lily loves to reside in warm and humid conditions. To replicate the natural environment of the rainforest, you can mist the plant regularly. Fill the spray bottle with dechlorinated water and spray it over the foliage and surrounding.
Note: Misting alone is not much helpful in generating humidity.
Better than misting, use the humidifier around the peace lily and other tropical houseplants, when the air is dry. Humidifiers are the cheap and best alternative when it comes to increasing the humidity for indoor plants. Check out our informative article to learn about more options.
Transplanting Peace Lily

Increased watering needs, yellowing leaves, roots getting crowded and showing on the surface are some of the signs. The average period in which re-potting is done ranges from every one to two years.
The recently transplanted peace lily might have a hard time standing upright without any support. As the roots of the newly potted plant are not well established. To remedy this, bury a stake or dowel near the plant and tie it using a wire or rope. Once the plant is established and can stay upright on its own gently remove the stake.
Cleaning the Leaves
Cleaning and wiping the peace lily foliage time to time is crucial to get rid of accumulated dust. Dirt caked on leaf surface affects the photosynthesis. Identify if your plant has lost its glossiness and natural color, it’s the time to clean it.
For this, get a soft cloth and rub it over the leaves. Or, dip it in a solution of one tablespoon of apple cider vinegar and one gallon of water and apply it gently on dirty leaves. Check out more apple cider vinegar uses here.
Peace lily care is easy–Adequate watering, and all day long bright indirect sunlight is enough to keep the plant healthy. Still, for prolific growth and flowers, you should fertilize it. A well-balanced 20-20-20 liquid houseplant fertilizer diluted to half or quarter strength is suitable. Apply it after every 4-5 weeks in the growing season (year-round in tropics) or when the plant needs nutrients.
NOTE: Plant producing green blooms and brown leaves can be an indication of overfertilization. Stop fertilizing as soon as you observe this symptom and flush the soil with water.
Pruning Peace Lily
