How to prune peace lily

After flowering, typically autumn; dead leaves any time. Cut spent flower spathes and stems at the soil line using clean scissors. Remove yellowed leaves the same way. Do not cut healthy green foliage.

As needed — remove spent flowers and dead leaves only. Peace lily needs only light tidying. Deadhead spent flower stalks by cutting them off at the base once blooms brown. Remove yellow or brown leaves at soil level. The plant does not require structural pruning — cutting healthy foliage is unnecessary and can stress it. Keep cuts clean to reduce disease entry.
