Peace Lily in Pots: How to Grow It at Home, Divide It, Get Flowers
A peace lily tells you when it is thirsty: the whole plant flops, then stands up again an hour after a drink. Here is how to grow peace lily at home: keep it in shade or bright indirect light, water when the top of the mix dries, feed very weakly, and split it in spring when it crowds the pot. Plan on it as a leafy plant that flowers now and then, and keep it away from mouths: the leaves contain irritating crystals.
At a glance
- Best method: division of a clump in February to March
- Light: partial to deep shade; never direct sun
- Pot: 3 to 5 litres (7 to 9 inches) for a small plant; 8 to 10 litres for a big clump
- Mix: rich and airy: 1 part soil, 1 part compost, 1 part cocopeat, a handful of coarse sand
- Flowers: white spathes stay white about 10 days, then green for a month or more
- Safety: toxic to children, cats and dogs if chewed

Where should a peace lily live in your city?
NC State Extension says not to place it in direct sun. That is the one rule that holds from Karachi to the hills.
- Karachi and the coast: shaded verandah or indoor room year round; humidity suits it.
- Multan, Sukkur, Bahawalpur: indoors from April to October, away from the cooler’s direct blast and dry AC air.
- Lahore, Faisalabad, Delhi: indoors near a north or east window; it hates frost nights, so never leave it outside in December.
- Islamabad, Peshawar and the hills: indoors all year in a warm room.
How do you divide a peace lily?
NC State Extension recommends division, with repotting in February or March. Late monsoon also works in warm cities.
- Water the plant the day before so the roots are supple.
- Tip it out and shake off loose mix.
- Find natural crowns: each fan of leaves with its own roots.
- Pull apart gently, or cut between crowns with a clean knife. Keep at least 3 leaves and plenty of roots per piece.
- Pot each in fresh mix at the same depth, in a pot only a little wider than the roots.
- Keep in shade and water lightly for two weeks. A few drooping leaves are normal.
Cuttings don’t work because the plant has no stems to cut, and seed is a breeder’s job. A divided piece usually settles in a month and may flower within the year.
Water from below and feed at a quarter strength
NC State Extension suggests watering from below and feeding at one quarter of the label strength, then flushing the mix to stop salts burning the roots. Stand the pot in a bucket of water for 20 minutes, let it drain fully, and once a month pour plain water through the top for a minute. Brown tips and edges drop off quickly with this routine in hard water areas.
How often should you water a peace lily?
- Summer: when the top 2 to 3 cm is dry; in a dry Multan room with AC, often every 2 to 3 days.
- Monsoon: less; check before watering.
- Winter: about weekly in a warm room, less in a cold one. Cold wet roots rot.
Don’t wait for the dramatic flop every time; repeated collapse browns the leaf edges. See our potting mix guide if water runs straight through or sits on top.
Why is my peace lily not flowering?
- Too dark. It survives deep shade but flowers best in bright, indirect light.
- Too young or just divided. Give it a season.
- Too much nitrogen. Lush leaves, no flowers.
- Cold room. Flowering slows in winter.
Nursery plants are often forced into bloom before sale, so a plant that flowered when bought and then stopped is normal, not failing.
Yellow leaves and pests: what to check first?
| Sign | Likely cause | First step |
|---|---|---|
| One or two old lower leaves yellow | Normal ageing | Cut off at the base |
| Many leaves yellow, soggy mix | Overwatering | Let it dry; check roots |
| Brown tips and edges | Sun, underwatering, dry air or salts | Move to shade; flush the pot |
| White fluff in leaf joints | Mealybugs | Wipe off; neem spray |
| Dusty, dull leaves | Dust blocks light | Wipe with a damp cloth monthly |
NC State Extension calls mealybugs the most common indoor pest. Our mealybug guide has the full routine.
Grow it or skip it?
| Situation | Verdict | Reason |
|---|---|---|
| Dim office or north room | Plant | One of the few flowering plants for shade |
| Toddler who mouths everything | Skip or keep high | Leaves burn the mouth |
| Cat that chews leaves | Skip | Listed as a problem for cats and dogs |
| Sunny balcony | Skip | Direct sun scorches it |

NC State Extension rates peace lily as medium severity: the leaves contain calcium oxalate crystals that cause mouth pain, burning lips and throat, drooling, vomiting and trouble swallowing if chewed. It is listed as a problem for children, cats and dogs. If a child chews a leaf, rinse the mouth with water and call a doctor or poison helpline; if swallowing or breathing is hard, go to emergency. Wear gloves when dividing if your skin is sensitive. See our poisonous plants list for others to watch.
Peace lily questions people ask
How often should I water a peace lily?
When the top 2 to 3 cm of mix is dry. That is often every few days in summer and weekly in winter.
Why is my peace lily drooping?
Most often thirst. If the mix is wet and it still droops, roots may be rotting; tip it out and check.
Can peace lily grow in water?
It can survive in water for a while, but it grows and flowers better in an airy mix.
Can I keep a peace lily in my bedroom?
Yes, if no small child or pet can reach it. It doesn’t need direct light.
Should I cut off green peace lily flowers?
Yes, once they turn green or brown, cut the stalk at the base. It doesn’t harm the plant.
Is peace lily a true lily?
No. It is in the arum family, not a true lily, which is why its toxicity differs from Lilium species.
Does peace lily clean the air?
A few pots won’t change room air in a way you’d measure. Ventilation does far more.
When should I repot a peace lily?
February or March, every couple of years, or when roots push out of the hole.
Is peace lily poisonous to dogs?
Yes, chewing it can cause mouth pain, drooling and vomiting. Call a vet if your dog eats some.
