Can peace lily survive outdoors?
You might be under the impression that peace lilies can only grow indoors, but that’s not true. They will grow well outside if you provide them a suitable outdoor location, preferably shaded and moist.
A peace lily will survive well outdoors in USDA hardiness zone 10-12 as these places have warmer climates. Plant your peace lily directly in the soil as ground cover or big planters.
But you need to bring the potted peace lily indoors to protect them from frost damage during winter. Outdoor peace lilies will require regular watering, pruning, and they should be placed or planted under shade for best results.
If you want to grow peace lily outdoors, you need to make sure that you understand the requirements as they will need more intensive care outside. If these requirements are not met, the plant can even die.

Light is crucial for every plant for performing photosynthesis to carry out their life processes. Peace lilies do well in indirect light and partial shade. Their light requirements will not change even when they grow outside.
Peace lilies are not capable of tolerating full exposure to sunlight. You should keep outdoor peace lily under dappled shade. They can tolerate the morning sun for about an hour but can’t be exposed to the afternoon sun.
You can place your peace lily in a location where it will receive the partial shade and no direct sunlight. You can also place it under the shade of a big tree.
What happens if you will expose your plant to direct sunlight?
Peace lilies are sensitive to direct sunlight, and excessive exposure will cause many problems to them, such as:
- The plant will burn out and get sunburns. Sunburn is a severe issue for peace lilies when it is placed outside.
- Hot afternoon hours are simply harsh and intolerable for your peace lilies. They will probably die if they do not get partial shade.
- The leaves will curl, wilt, and get discolored.
Therefore, you must ensure that your peace lilies are not exposed to direct light by keeping them in partial shade.
Peace lilies are tropical perennials, which means that they thrive in warm conditions. It would be best if the temperature is higher, as peace lilies do not like low temperatures.
Peace lilies can survive outdoors in zones 10 and 12 as temperatures in these zones will suit their requirement. They are not adaptable to uncertain changes in temperatures.
So, a drastic change might harm them, and in such cases, you have to bring them indoors.
What temperatures can they tolerate?
Peace lilies prefer a consistent temperature of around 65-80°F during the day and 10°F lower at night. They are hardy plants, and they will struggle to survive in frosty winters, so you should protect your peace lily from winter drafts.
You might have to bring your peace lily indoors if the conditions are too harsh for them and when the temperature reaches 45°F, which could damage their leaves, stems, and roots.
It would help if you covered your garden peace lilies with a bedsheet, blanket, or plastic sheets to protect them from frost.
Peace lily prefers high humidity. They thrive well when humidity is above 50%. They will easily survive outdoors if the air humidity is around 50% or more.
They like moist environment and develops some problem in dry conditions. To increase the humidity around them, you can mist them, especially in summers.
You can also place your outdoor potted peace lily in a tray of moistened gravel to increase humidity around the plants.
How will low humidity hamper your outdoor peace lilies?
Peace lilies do not like dry air conditions, and low humidity will cause your plants to stop blooming. Low humidity will make the soil dry and will create drought stress for the plant.
Due to low humidity, plants will have brown tips on leaves. So it will be better to keep a humidity check on peace lilies for maintaining the humidity levels.
Peace lily needs consistently moist soil, but they never like standing in water. Generally, indoor peace lily requires weekly watering to keep them hydrated.
If you are growing them outside, their water requirements will increase because of more heat and light. The peace lilies will lose a lot of moisture from the leaves over time, and you have to make sure that you care for the plant properly.
For that, you have to maintain a watering schedule.
Since it’s a tropical plant, you don’t have to think about excessive watering, although it’s always better to check the soil before adding more water as excessive watering can cause root rot issues to peace lilies.
How often do I water my peace lily outside?
If you’re growing peace lilies outside, they will need a lot of water to keep them hydrated. You will have to water them several times during the week in the summers.
You should water the peace lily less during the winter months as they will conserve more water when temperatures fall.
Check the soil by poking a finger in the soil. If the soil feels dry, add more water to the plant, and if the soil feels moist, it will be better to hold off your watering for a day or two and check back again.
Peace lilies are sensitive to cold and chlorinated water so avoid using either of these to your plant.
Peace lilies will never enjoy strong winds. They can easily get damaged by strong winds. Never place them in an area of strong winds. Both hot and cold drafts will undoubtedly harm your plant.
Where should I place my peace lilies outside?
The best location of peace lily outside is a shaded spot with early morning sunlight or dappled sunlight. It is sensitive to direct sunlight, and it will scorch the leaves of your peace lilies.
So, find a spot for the peace lily in your garden to protect it from strong winds where the water doesn’t pool after the rain.
Peace lilies prefer fertile and quick-draining soil. Heavy soil mix can create problems for your peace lily that is placed outside.
You can add compost to the soil while planting the peace lily in the garden. Mulching around peace lily is an excellent way to ensure their healthy growth.
What nutrition will be good for outdoor peace lilies?
Peace lilies are significantly less demanding plants, and they can happily grow will little fertilization.
However, you can feed your peace lily using a balanced 10:10:10 formula diluted at the rate of 1/8 teaspoon of fertilizers per gallon of water for giving them nutrition.
Pest and diseases
Outdoor plants are at risk of getting infected diseases and pests more than indoor plants.
So you will have to be very careful when you place your peace lily outdoors, as they will get exposed to disease and pests, and it won’t take much time before the plant gets attacked by them.
Pests like mealybugs, aphids, and scales can cause damage to the plant if they are left unchecked. For instance, you will notice white residue developing on plants if mealybugs infest them.
How can I prevent pests and disease for my outdoor peace lilies?
To prevent pests and diseases, you have to be careful by closely observing the peace lily to identify any sign of infestation. If your plants have pests, apply pesticides and spray them on the plant regularly for a few weeks.
Most importantly, you should prune the outdoor peace lilies to keep them away from pests and diseases.
