- 01
When to repot
Repot when roots are densely packed, circle the top of the soil or emerge through drainage holes. A newly bought peace lily can often stay in its original pot for one to two years, but the roots tell you when.
Check roots in spring as growth starts. February and March are a good window, but root condition matters more than the month.

Choosing the next pot
Use a pot only a few centimeters larger than the current one and do not overpot. Peace lilies prefer to stay somewhat pot-bound.

How to repot
Use peat-free multipurpose potting mix with perlite, ideally in a 3:1 ratio of potting mix to perlite, lift the plant to check the root ball and move it into the slightly larger pot with free drainage.

After repotting
After repotting, keep the medium damp but not soggy, allow excess water to drain and avoid standing water. Do not use overpotting to compensate for a watering problem.
