Repotting a Peace Lilly

When to Repot

• Repot a peace lily when the plant’s root growth has begun to crowd the container and the plant has become pot-bound. A pot-bound plant often requires frequent watering and may not grow well. Examine the pot’s drainage holes to see if any of the peace lily’s roots are showing. If they are, it is time to repot the plant. The best time to repot is during the early spring, which is a time of slow growth; this gives the plant ample time for its roots to grow into the new pot before winter.

Soil

• Choose a potting mix or potting soil especially created for potted plants when repotting your peace lily. Peace lilies prefer a humus-rich potting soil, so a composted soil or peat mixture is ideal. Wet the potting soil prior to repotting the peace lily to make sure it absorbs water evenly. Do not use soil from your garden to repot the peace lily; doing so might introduce pests and root disease.

Choosing a Pot

• When selecting a pot to use for repotting, choose between plastic or clay. The advantages of plastic include lighter weight and affordability. Clay pots are heavier and sturdier, making it less likely the plant will tip over accidentally. However, plants in clay pots need to be watered more frequently because the clay draws water from the soil. Use a pot that is 1½ times larger than the pot from which you are repotting the peace lily. Make sure the pot has drainage holes to allow excess water to drain so the peace lily is not standing in water.

Re-potting

• Repot the peace lily when the soil is slightly moist. Prepare the new pot by placing a layer of potting soil at the bottom. Spread your fingers, and place your hand over the old pot to catch the peace lily as you turn the pot over; gently knock the root ball out of the pot. Separate the roots if they are densely matted. Place the peace lily in the new pot, and add soil underneath it until it is at the same height as it was in the old pot. Fill in around the root ball with potting soil. Tamp the soil lightly to firm it. Water the newly potted peace lily thoroughly and allow to drain. Return the peace lily to its normal location.
