When it comes to easy indoor plants, it doesn’t get much easier than peace lily. This tough plant even tolerates low light and a certain amount of neglect. However, repotting a peace lily plant is occasionally necessary, as a rootbound plant isn’t able to absorb nutrients and water and may eventually die. Fortunately, peace lily repotting is easy! Keep reading to learn how to repot a peace lily.

When to Repot Peace Lilies

Does my peace lily need repotting? Peace lily is actually happy when its roots are slightly crowded, so don’t rush to repot if the plant doesn’t need it. However, if you notice roots growing through the drainage hole or circling around the surface of the potting mix, it’s time.

If the roots become so compacted that water runs straight through the drainage hole without being absorbed into the potting mix, it’s time for an emergency peace lily repotting! Don’t panic if this is the case; repotting a peace lily isn’t difficult and your plant will soon rebound and grow like crazy in its new, roomier pot.

How to Repot a Peace Lily

Select a container only a size larger than the peace lily’s current pot. It may sound logical to use a larger pot, but a large amount of damp potting mix around the roots may contribute to root rot. It’s much better to repot the plant into gradually larger containers.

Water the peace lily a day or two before repotting.

Fill a container about one-third full with fresh, high quality potting mix.

Remove the peace lily carefully from the container. If the roots are tightly compacted, loosen them carefully with your fingers so they can spread out in the new pot.

Set the peace lily in the new pot. Add or subtract potting mix to the bottom as needed; the top of the root ball should be about an inch below the rim of the pot. Fill in around the root ball with potting mix, then firm the potting mix lightly with your fingers.

Water the peace lily well, allowing excess liquid to drip through the drainage hole. Once the plant has completely drained, return it to its drainage saucer.
