Peace Lily is a long game. From seed it takes 1-2 years (for flowering) before you see a harvest, which is why most growers start from a nursery plant. Container growing is entirely possible, but the container has to be sized for a plant that will live in it for years.
Short answer
Grow peace lily in a 5 litre container at least 15 cm deep, watering about 500 ml per 10 litres of soil every 7 days, and keep temperatures between 18 and 29 °C. First harvest comes 365 days after sowing.
Where to plant it
What size pot does peace lily need?
5 litres and 15 cm deep is the realistic minimum for a single plant. Pick a container below to see what changes.
| Container | Minimum size | Depth | Notes |
|---|---|---|---|
| Pot | 5 L | 15 cm | Ensure good drainage |
| Grow bag | 5 L | 15 cm | Good for aeration |
| Open ground | — | — | Not suitable for outdoor ground planting in most climates |
| Raised bed | — | — | Not typically grown in raised beds |
Watering
How often should you water peace lily?
Every 7 days through the growing season, at about 500 ml per 10 litres of soil — every 4 days in hot weather, every 10 days when it turns cool. Water at morning. Bottom watering or top watering until drainage works best.
Too little water
- drooping leaves
- yellowing leaves
- brown leaf tips
Too much water
- yellowing leaves
- mushy stem
- root rot
- stunted growth
Avoid: standing water; completely dry soil; direct water on flowers.
Climate
Can you grow peace lily where you live?
No hardiness zone needed — compare your actual temperatures against the plant's own limits.
| Ideal range | 18 – 29 °C |
|---|---|
| Survives | 10 – 32 °C |
| Germinates above | 20 °C — best at 25 °C, about 30 days |
| Flowers drop | above 30 °C, or below 15 °C |
| Frost | Highly sensitive — will not survive it |
The flower-drop thresholds matter more than the survival ones. A plant can be perfectly alive at 32 °C and still give you nothing.

Common mistakes
Why peace lily fails, and how to avoid it
- A container that is too small
Below 5 litres the root run is too shallow. The plant grows, flowers late, and drops whatever it sets because it cannot support the crop.
- Watering too lightly
A daily splash wets the top few centimetres and nothing else. Peace Lily wants about 500 ml per 10 litres of soil — one deep soak beats three shallow ones.
- Ignoring the flower-drop threshold
Above 30 °C, or below 15 °C, flowers fall before setting. The plant can look perfectly healthy and still give you nothing — shade it through the hottest hours.
- Harvesting too late
Left too long the colour changes, seeds harden and the flavour sharpens. Pick on the signs listed below, not on the calendar.
- Planting it beside Cactus Succulents
Require very different care: high light, low humidity, and infrequent watering, which are opposite to Peace Lily's needs.
- Leaving it out through a cold snap
Peace Lily is highly frost-sensitive. One night below 10 °C can end the plant outright — bring containers in or cover them.
Companions
What to plant with peace lily
Good neighbours
Thrives in similar indirect light and humidity conditions, and is known for air purification.
Shares similar care requirements (indirect light, consistent moisture) and contributes to indoor air quality.
Excellent air purifier, tolerates lower light, and can create a visually appealing contrast with Peace Lily's broad leaves.
Many ferns (e.g., Boston Fern) prefer high humidity, which can benefit Peace Lilies when grouped together, creating a microclimate.
Keep apart from
Require very different care: high light, low humidity, and infrequent watering, which are opposite to Peace Lily's needs.
Plants that require direct or very bright light will not thrive in the indirect, lower light conditions preferred by Peace Lilies.
Plants that are heavy feeders will quickly deplete nutrients in shared soil, leaving Peace Lily undernourished.
Problems
Peace Lily pests and diseases
Each lists the weather that brings it on, so you know when to start checking rather than reacting once it's established.
Spider Mites humidity <50% · temp >25
Tiny pests that cause stippling on leaves and fine webbing, especially in dry, warm conditions. Increase humidity and wipe leaves.
Mealybugs humidity any · temp any
White, cottony masses found in leaf axils and undersides of leaves. Dab with alcohol-soaked cotton swab.
Fungus Gnats humidity >70% · temp 18-24
Small, dark flying insects often seen around the soil surface, indicating overwatering. Let soil dry out between waterings.
Root Rot humidity any · temp any
Caused by overwatering and poor drainage. Leaves yellow, droop, and plant eventually dies. Ensure proper drainage and allow topsoil to dry slightly.
Leaf Tip Burn humidity <60% · temp >28
Brown tips on leaves, often due to low humidity, over-fertilization, or fluoride/chlorine in tap water. Use filtered water and increase humidity.
Yellowing Leaves humidity any · temp any
Lower leaves yellowing can indicate over/underwatering, nutrient deficiency, or natural aging. Assess watering habits and light.
Brown Spots humidity any · temp any
Can be caused by direct sunlight (sunburn), fungal infections (if humidity is too high without air circulation), or cold drafts.
Lack Of Flowers humidity any · temp any
Commonly due to insufficient light, inconsistent watering, or lack of proper fertilization. Ensure bright, indirect light and consistent care.
Drooping Leaves humidity any · temp any
Most often a sign of underwatering (soil too dry), but can also be overwatering (root rot), or temperature shock. Check soil moisture first.

Questions
Peace Lily: common questions
How long does peace lily take to grow?
About 365 days from sowing to the first harvest. Warm weather pulls that forward; cool weather pushes it back.
What size pot does peace lily need?
At least 5 litres and 15 cm deep for one plant.
How often should I water peace lily?
About 500 ml per 10 litres of soil, every 7 days in normal weather — every 4 days when it is hot and every 10 days when cool. Water in the morning.
What temperature does peace lily need?
It does best between 18 °C and 29 °C and survives from 10 °C to 32 °C. Seed needs soil above 20 °C to germinate, ideally around 25 °C.
Can I grow peace lily in winter?
Not outdoors anywhere that frosts — it is highly frost-sensitive and will not survive it. In a frost-free winter it grows slowly; anywhere colder, treat it as a warm-season crop.
How do I know when peace lily is ready to harvest?
Spathe turns green or brown; Leaves turn yellow or brown. Once picked: not applicable (pruning for plant health)
