Peace lilies can stay outside under the right conditions and with proper care.
This tropical plant is quite adaptable and can thrive outdoors in shaded or semi-shaded spots.
However, peace lilies need protection from harsh sun, extreme temperatures, and heavy winds if kept outside.
In this post, we’ll explore whether a peace lily can stay outside, the best conditions to keep it healthy outdoors, and how to care for your peace lily when growing it outside.
Let’s dive right in!
Why a Peace Lily Can Stay Outside
Peace lilies can stay outside because they are tropical plants that naturally grow under the canopy of trees in warm, humid environments.
They prefer indirect light, which makes shaded outdoor spaces ideal for their growth.
1. Peace Lilies Are Tropical Shade-Loving Plants
Peace lilies thrive in filtered sunlight similar to what they would get in their native rainforests.
This means they do well in shady patios, covered porches, or under large trees where they get dappled light rather than harsh, direct sun.
Direct sun exposure outside can scorch their leaves and stunt their growth.
2. Suitable Outdoor Temperatures Support Growth
Outdoors, peace lilies can stay outside comfortably if the temperature remains between 65°F and 85°F (18°C to 29°C).
They don’t tolerate freezing temperatures or harsh cold snaps, which can kill the plant.
If you live in a climate with frost or winter cold, peace lilies need to be brought indoors or protected to survive.
3. Outdoor Humidity Helps Peace Lilies Thrive
Peace lilies love humidity, so in many outdoor settings with naturally higher humidity levels, they flourish better than in dry indoor air.
This outdoor humidity helps keep their leaves lush and supports their flowering.
If your outdoor humidity is low, mist your peace lily regularly to mimic its preferred environment.
4. Peace Lilies Benefit From Fresh Air
Peace lilies kept outside get better air circulation compared to indoors, which can lead to healthier plants and less pest or fungal issues.
Just be sure to protect your peace lily from strong winds that can damage the leaves.
Best Conditions for a Peace Lily to Stay Outside
If you want your peace lily to stay outside, it’s important to create the right environment to mimic its natural habitat.
1. Provide Indirect or Filtered Light
Place your peace lily in a spot that receives bright, indirect sunlight.
Filtered light through tree leaves or translucent porch covers is perfect.
Avoid placing it under direct afternoon sun, especially in summer, as this can cause leaf burn.
2. Maintain Warm, Stable Temperatures
Keep your peace lily outdoors only if the temperatures stay consistently warm.
At night, temperatures below 55°F (13°C) can stress the plant, so consider moving it indoors or to a protected area during cooler months.
A good rule of thumb is to bring the peace lily inside any time freezing or frost is expected.
3. Ensure Adequate Humidity
If your area is dry, supplement humidity by misting the leaves regularly or placing a humidity tray beneath the pot.
Peace lilies love humidity levels above 40%, which many outdoor climates naturally provide.
4. Use Well-Draining Soil and Water Appropriately
Keep your peace lily in a pot with good drainage to avoid standing water, which leads to root rot.
When outdoors, rainwater can sometimes overwater the plant, so monitor soil moisture frequently.
Water the peace lily when the top inch of soil feels dry to the touch, ensuring even watering without waterlogging.
5. Protect From Pests and Environmental Damage
Outdoor peace lilies may attract pests such as aphids, spider mites, or mealybugs more than indoor plants.
Check leaves often and wash pests off or treat with insecticidal soap if needed.
Also, shield the plant from strong winds, heavy rain, or hail that can damage delicate leaves.
How to Care for a Peace Lily When It Stays Outside
Caring for a peace lily outside requires some adjustments compared to indoor care.
1. Regular Watering Adjusted to Weather
Outdoors, your peace lily’s water needs change depending on rain and warmth.
After rain, check the soil before watering to prevent overwatering.
During hot or windy days, the plant might dry out faster and need more frequent watering.
2. Fertilizing for Outdoor Growth
Peace lilies grown outside generally grow faster and may require fertilizing every 6 to 8 weeks during the growing season.
Use a balanced, water-soluble fertilizer diluted to half strength to avoid fertilizer burn.
3. Pruning Dead or Yellow Leaves
Outdoor peace lilies can get more leaf damage from environmental factors.
Trim away yellowing or brown leaves to keep the plant looking healthy and help redirect energy to new growth.
4. Repotting and Soil Refreshing
Peace lilies outdoors may outgrow their pots faster due to better growing conditions.
Repot your plant every 1-2 years into a slightly larger pot with fresh, well-draining soil to keep the roots healthy.
5. Bring Indoors When Needed
Even though peace lilies can stay outside, they’re sensitive to cold and freezing.
Plan to bring your peace lily indoors when night temperatures dip below 55°F (13°C) or if a freeze is forecasted.
This protects the plant and ensures it survives through winter.
Common Challenges of Keeping a Peace Lily Outside
While peace lilies can stay outside, it’s important to be aware of potential challenges when growing them outdoors.
1. Sunburn and Leaf Scorching
Too much direct sunlight will cause brown spots and dry leaf edges.
If you notice scorched leaves, move the plant to a shadier spot.
2. Pests and Disease Risks
Outdoor environments have more exposure to insects and fungal problems than indoors.
Regularly inspect your peace lily and treat early to avoid infestations that can weaken the plant.
3. Overwatering from Rain
If your peace lily is in a pot and left outside, heavy rains can saturate the soil, leading to root rot.
Ensure the pot has drainage and consider bringing it under cover during extended rainy periods.
4. Temperature Extremes
Cold nights or heat waves can stress your peace lily.
Be prepared to move the plant indoors or to shade as weather changes.
5. Wind Damage
Strong outdoor winds can tear the soft leaves or knock the plant over.
Position the peace lily in a sheltered location to prevent this damage.
So, Can a Peace Lily Stay Outside?
A peace lily can definitely stay outside if it’s placed in the right conditions that mimic its natural tropical habitat.
These include indirect light, warm temperatures, adequate humidity, and protection from extreme weather.
Peace lilies grow well outside in shaded areas with good airflow and regular watering but need to be brought indoors or sheltered during cold or frosty weather.
With proper care, your peace lily can thrive outdoors and reward you with lush, glossy leaves and beautiful white blooms.
Whether you use it as a patio plant, in a garden corner, or on your porch, peace lilies make great outdoor companions in suitable climates.
So go ahead and enjoy the charm of your peace lily outside—just keep an eye on those conditions and adjust as needed!
