How to care for peace lily outdoors

There are certain requirements to know to take care of peace lily. The plant is very delicate outdoors, and one mistake in the climate, temperatures, or water, can result in it dying. 

Some causes result from human error, and others are natural; however, this doesn’t limit you from caring for the plant. If you follow the requirements, you won’t have to worry about any problems. 


The best climatic conditions for this plant are in tropical or subtropical areas. Those areas have a USDA zone of 10 to 12, and the temperatures are warm throughout the year. 

If you live in an area with a cool climate, you can decide to plant them in a pot outdoors. When the temperatures cool to frost, you can take them indoors until the temperatures rise. 


Water is important for the growth of lilies. To care for peace lily outdoors, you must give it enough water. Some gardeners often overwater and others underwater. This is a common problem for most people who don’t know the right time to water their plants. 

If you are not receiving any rain, water them once a week with 1 to 2 inches of water. Ensure that after watering, the soil remains moist and not wet. Wet soil can lead to root rot and fungal infections. 

Another method you can use to ensure your peace lily plant gets moist soil is water after the soil is dry. You can use the finger test to check. It works by inserting 1-inch of your finger into the soil near the roots, and then, if the soil on your finger is dry, you can water the plant. 

Also, you can use a moisture meter to measure the moisture present in the soil. 


The plant requires bright outdoor light but in the shade. You can give it partial or deep shade and ensure it doesn’t come into contact with direct sunlight. The sun can burn the foliage. 

The leaves turn brown when it receives too much sunlight. But, with partial sunlight, it can receive the recommended amount of light to grow. 


Even though you can’t control the temperature changes outdoors, you should ensure it doesn’t drop below 55 degrees Celsius. If the temperatures drop below that, you can move it indoors and provide extra heating until summer. 

When planting peace lily outdoors, place it under shade during the summer. That way, the plant is cool and warm.  

Pruning foliage. 

Another thing to do when planting peace lily outdoors is regularly prune the foliage. It might seem odd, but removing excess foliage leaves space for new and fresh foliage to grow. 

Other than excess foliage, you can prune brown or wilted leaves. Always use clean and sharp pruning shears to cut the foliage. Make clean cuts to avoid damaging fresh tissues.


Adding fertilizer to the soil is another way to care for peace lily outdoors. Indoor lilies can survive with minimal food, but for outdoor gardens, you must increase the fertilizer to boost their growth. In the spring and fall, you can fertilize it once.

Can you move indoor peace lilies outdoors?

Yes, you can move indoor peace lilies outdoors, but there are important factors to consider. Peace lilies thrive in the low light conditions typical of indoor spaces, so if you decide to move them outside, choose a location with filtered sunlight or partial shade to avoid leaf scorching.

Ensure that the outdoor temperature is within their preferred range of 65-80°F (18-27°C) and be cautious in colder climates, as peace lilies are tropical plants sensitive to cold. If your region experiences cold winters, bring them back indoors during the colder months. Keep an eye on their water needs, as outdoor conditions may affect their moisture requirements differently than indoor settings.
