Quick Answer
Peace lilies are not heavy feeders, so the goal is steady nutrition rather than pushing growth. With Peace Lily Fertilizer, mix 1 teaspoon per quart (32 oz) of water and feed every 1–2 weeks in spring and summer, then every 4 weeks in fall and winter. Mix it into your normal watering; there is no separate routine to keep.
How to fertilize a peace lily through the year
Focus feeding on the periods when you see active leaf and root growth: new leaves rising from the center of the clump, and the plant filling out its pot. That is spring and summer in most homes. Through fall and winter the plant slows and the schedule drops to every 4 weeks.
A peace lily wilts dramatically when thirsty and recovers within hours of a drink, which makes its watering rhythm easy to read. Feed on a watering day, never into a pot that is already soggy.
| Method | Amount | How often |
|---|---|---|
| Watering can | 1 tsp per quart (32 oz) of water | Spring and summer: every 1–2 weeks |
| Watering can | Same dilution | Fall and winter: every 4 weeks |
| Leaf misting (optional) | ½ tsp per pint (16 oz) of water | Every 1–2 weeks |
How much fertilizer should you give a peace lily?
One teaspoon per quart. Peace Lily Fertilizer is a gentle 3-1-2 formula that provides ongoing nutrition for lush green foliage, healthy roots and steady new growth. Peace lilies can be sensitive to accumulated salts, so use the fertilizer at the recommended strength, avoid overfeeding, and let excess water drain away rather than sitting in the saucer.
Liquid vs. granular for peace lilies
A granule or spike sits where you put it and releases over weeks, mostly into the soil directly beneath it, and in a small pot that means a concentrated patch of salts against a few roots. A liquid goes on with the water, reaches the whole root ball evenly, and you control the strength every time. The nitrate nitrogen in Peace Lily Fertilizer is taken up by the roots directly, without waiting for soil microbes to convert it, which is why the response shows on the next leaves rather than next season.
Signs a peace lily may be underfed
- New leaves coming in smaller and paler than the older ones
- A clump that has stopped producing new leaves during the bright season
- Older leaves yellowing evenly on a plant that is watered on a steady rhythm
- No flowers for a year or more on a plant in bright, indirect light
Yellow leaves also commonly result from watering issues, aging foliage, root stress or other growing conditions, so determine the likely cause before increasing the feeding rate. Where nutrition is part of the problem, Peace Lily Fertilizer corrects it on the next leaves.
Signs you may be fertilizing too much
Feeding is not the answer to every problem, and more of it causes a few. A white crust on the soil surface or the rim of the pot is fertilizer salt building up. Brown, crispy leaf tips and edges on otherwise green leaves often follow, and in a bad case new growth comes in stunted while the soil stays wet. If you see those, flush the pot: water slowly until it runs freely from the drainage holes, let it drain, and repeat once. Then go back to the schedule above at the same dilution rather than a weaker one; dilution is already what keeps Peace Lily Fertilizer gentle.
Why won’t my peace lily flower, and what causes brown tips?
If the plant produces plenty of leaves but no flowers, insufficient light is worth checking before fertilizer. Peace lilies survive in low light but flower in bright, indirect light, and increasing fertilizer will not trigger blooms if the plant is not receiving the conditions it needs to flower. Continue appropriate nutrition during active growth and move the plant closer to a window.
Brown leaf tips are usually salts. Fertilizer is one source, and so is the water: tap water high in minerals or softened water builds up the same way. Use the fertilizer at the recommended strength, water with filtered or rested water if yours is hard, and flush the pot with plain water every month or two.
