Repotting a Crowded Plant

Find a new pot that is one or two sizes larger than the original. Plant pots for houseplants typically come in sizes from 4 to 12 inches, with sizes noted with even numbers. For example, if your plant is currently in a 6-inch pot, the next larger size is an 8-inch one.

Cover the drainage holes in the bottom of the pot with a broken shard of a plant pot or several large pebbles. This prevents the drainage holes from clogging with soil as you water the plant.

Water the plant thoroughly, and allow it to set for one hour. This makes removing the plant from the pot easier and provides the plant with the moisture needed to combat the stress of being moved.

Fill the new pot one-third to half-way with fresh potting medium. The type of soil you need depends on the type of plant you are growing. Follow the recommendations for your specific plant.

Place one hand over the top of your plant so the main stem of the plant rests between your index and middle fingers. Place your palm across the surface of the soil to support the plant.

Invert the pot so the plant rests on your hand. Tap the bottom of the pot to loosen the soil and to slide the plant free from the pot.

Remove excess soil with your fingers, and inspect the roots. Healthy roots are white or tan. Cut away any darkened or diseased roots with a sharp knife. Loosen tightly coiled roots with your fingers.

Position the plant into the new plant pot, and spread the roots out over the soil. The crown -- the point where the leaves meet the roots -- should rest at soil-level. Adjust the plant as necessary. Fill in around the roots with the soil, and firm it down gently with your hands.

Water thoroughly until water runs freely through the bottom of the pot. Place the plant in the recommended lighting, and resume regular care.
