Why are my peace lily leaves turning yellow?
Most often it's overwatering or natural aging. Plants yellow from the bottom up when they're stressed — usually water, light, or nutrients. Check the soil first: if it's soggy, you've been too generous with the watering can.
Peace lilies yellow from soggy soil or simply from old leaves dying off as the plant grows. If it's just the oldest outer leaves yellowing, that's normal. If it's widespread, check that the soil isn't staying wet.
Should I cut the yellow leaves off my peace lily?
Yes — once a leaf is fully yellow it's not coming back, and it's draining energy your plant could spend on new growth. Snip it clean at the base with sharp scissors. A leaf that's only partly yellow can hang on a while longer while you fix the underlying issue.
How do I fix yellow leaves on my peace lily?
Start with the soil. Let the top inch or two dry before watering again, and make sure your pot actually drains. Then check light — a peace lily sitting too dark will slowly yellow. Fix one thing at a time so you know what worked.
Why are my peace lily leaves turning yellow after watering?
If several leaves yellow right after a watering, you likely overdid it — the soil's too wet. Let it dry out more between waterings. Peace lilies like moist soil, not soggy.
