All you need to know for growing peace lilies outdoor –
Can you grow peace lily outdoors ?
The simple answer is yes they can . But it needs some special care ☘️ which I will discuss in this article. Peace lilies originate from the tropical rainforests of Central and South America, where they grow under tree canopies in warm, humid environments. This makes them suitable for outdoor cultivation in USDA Hardiness Zones 10-12, where temperatures remain mild year-round.
Climate Considerations
- Ideal Temperature: 65-80°F (18-27°C)
- Cold Sensitivity: Below 55°F (12.7°C) can damage the plant
- Humidity: Prefers 50%+ humidity for optimal growth
If you live in a cooler climate, you can grow peace lilies outdoors during warmer months but should be moved indoors before temperatures drop.
Sunlight Requirements
- Best Placement: Partial shade with indirect sunlight
- Avoid Direct Sunlight: Can cause leaf scorching
- Ideal Spots: Under trees, on covered patios, or in shaded garden beds
Choosing the right location with consistent warmth and shade is key to successfully growing peace lilies outdoors.

- Best Mix: for making the soil mix you can use 50% potting soil, 25% compost, 25% perlite .
- Avoid: Heavy clay soil (can cause root rot)
If you are going to plant this in container this guide will help you-
Planting peace lily in the Ground or Containers
Ground Planting
- Choose a well-drained area with good organic matter
- Dig a hole twice the size of the root ball
- Add compost to enrich the soil before planting
Container Planting
- Use a pot with drainage holes
- Select a 12-inch (30 cm) pot or larger
- Ensure soil remains consistently moist but not soggy
I will suggest you to plant in a container. As if in your area in the temperature falls under 18 ° Celsius then you have to bring the plant in your home.
Tip: Proper soil and planting techniques help peace lilies establish strong roots outdoors.
Watering & Humidity Control
While peace lilies love moisture, but improper watering can cause stress.
How Often to Water?
- Warm Months: 2-3 times per week
- Cooler Months: Once per week
Tip – only water when top 1 inch (2.5 cm) feels dry as it sometimes can be dried up faster than you think so check every day.
Humidity Requirements
Peace lilies require 50-70% humidity outdoors.
- Increase Humidity:
- Place near water features (ponds, fountains)
- Use mulch to retain soil moisture
- Group with other tropical plants
Proper watering and humidity control prevent drying out and leaf wilting.
Fertilization and Growth Boosting
Here are many types of fertilizer like liquid fertilizer, slow release fertilizer and also organic fertilizers ect. So, I have listed them & how to use them and their benefits .
Liquid fertilizer
For peace lilies, apply liquid fertilizer every 4–6 weeks during the growing season (spring and summer). Reduce feeding in fall and winter when growth slows down.
How to use liquid fertilizer for peace lilies outdoor growth
- Dilute to half-strength to prevent over-fertilization.
- Apply after watering to avoid root burn.
- Use a balanced fertilizer (e.g., 10-10-10 or 20-20-20).
- Skip fertilizing in winter unless the plant is actively growing indoors.
Slow-Release Fertilizer
It provides steady nutrients over time.Less maintenance—only apply every 2–3 months instead of every few weeks.Works well with liquid fertilizer for a balanced feeding plan.
How to Use Slow-Release Fertilizer for Peace Lilies:
- 1. Choose a balanced formula like 10-10-10 or 14-14-14.
- 2. Apply every 2–3 months during spring and summer.
- 3. Sprinkle it around the base and lightly mix it into the topsoil.
- 4. Water after applying to help nutrients release
This way, your peace lily gets a constant nutrient supply while you use liquid fertilizer for quick boosts when needed.
Organic Fertilizer
Organic fertilizers improve soil health naturally, providing essential nutrients while enhancing microbial activity. They are a great eco-friendly alternative for peace lily care outdoors and help sustain long-term plant health.
How to Use Organic Fertilizer for Peace Lilies:
- Compost or Aged Manure – Apply a thin layer around the base every 2–3 months to enrich the soil.
- Worm Castings – Mix a small amount into the topsoil every 2 months for slow nutrient release.
- Banana Peel Fertilizer – Chop banana peels and bury them near the roots every 4–6 weeks for a natural potassium boost.
- Homemade Organic Liquid Fertilizer – Use compost tea or fish emulsion every 4–6 weeks for a quick nutrient supply.

Other Fertilizers for Peace Lilies
Besides liquid, slow-release, and organic fertilizers, here are some other beneficial options:
Epsom Salt (Magnesium Boost)
- Helps keep leaves deep green and prevents yellowing.
- Apply 1 tbsp per gallon of water every 2 months.
Coffee Grounds (Mild Acidic Fertilizer)
- Enhances soil acidity slightly, which peace lilies prefer.
- Sprinkle lightly around the base every 6–8 weeks to avoid over-acidification.
Using a mix of liquid, slow-release, and organic fertilizers ensures steady growth, healthy foliage, and frequent blooms while keeping the soil naturally enriched.
Tip – Avoid over-fertilizing, as it can cause brown leaf tips.
