How to repot Spathiphyllum wallisii

Repot a peace lily when roots are packed, circle the soil surface or emerge from drainage holes. Use a slightly larger pot, not a large jump.

When to repot

What to inspect

Repot when roots are densely packed, circle the top of the soil or emerge through drainage holes. A newly bought peace lily can often remain in its original pot for one to two years, but root evidence takes priority.

What changes it

Check roots in spring as growth starts. NCSU gives February and March as its peace-lily repotting window, but root condition takes priority over a universal month.

Use the smallest practical size increase

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.

Move the rootball without unnecessary damage

How to repot

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

Keep light, water and support steady

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.
