Other Tips to Help Your Peace Lily Flower
Fertilizer alone won’t guarantee blooms if the environment isn’t right.
Here are a few extra tips to help your peace lily flower.
1. Provide Bright, Indirect Light
Peace lilies need bright, indirect light to bloom consistently.
Too little light is a common reason peace lilies fail to flower.
Place it near an east-facing window or a few feet from a bright window.
Direct sunlight can scorch the leaves, so filtered light is best.

Peace lilies prefer to be a little root-bound.
Snug roots make the plant focus energy on blooming.
Don’t repot until roots are circling the pot and emerging from drainage holes.
3. Maintain Consistent Moisture
Peace lilies like consistently moist but not soggy soil.
Let the top inch dry out between waterings, then water thoroughly.
Drought stress can cause buds to drop before they open.
Waterlogged soil can lead to root rot, which stops blooming.
Pairing proper watering with the right fertilizer is the best way to feed a peace lily to make it flower.
4. Keep Temperatures Steady
Peace lilies prefer temperatures between 65 and 80 degrees Fahrenheit.
Keep them away from cold drafts and heat vents.
Sudden temperature swings can stress a peace lily and stop blooming.
