The peace lily is a low-maintenance houseplant with long green leaves and white flowers. While the peace lily can be grown outside in humid climates, it's primarily found indoors in the UK. Peace lilies fare best in shade to partial sun environments; their leaves will turn yellow with exposure to too much sun. While the peace lily does not require much pruning, deadheading the flowers and trimming back old growth will promote overall plant health and spur new growth.

Things you need
Inspect the peace lily for dead or dying blooms and withered leaves. Since these plants are quite bushy, you will need to brush the leaves aside with your hands to see old growth.
Using your scissors, cut dead leaves at the base and remove from the plant. Discard these in a rubbish or compost bin.
Snip blooms off the at the base in the same manner once they are past their prime or if you wish to display them in a vase. Cutting blooms encourages the growth of new ones, keeping your plant visually attractive.
Improve the plant's appearance by trimming low-hanging leaves that are yellowing; snip them off at the base. Remove to a rubbish or compost bin.
Tips and warnings
- Dead leaves look brown and curled.
- Since the peace lily is predominantly an indoor plant, prune leaves and flowers on an as-needed basis rather than on a seasonal schedule.
