Transplant Potbound Houseplants
Spring is a great time to transplant potbound houseplants.
One option is to move them into a slightly, 1 to 2 inches in diameter, larger container. Loosen any circling roots and fill in the extra space with a well-drained potting mix. Adjust watering as needed for the larger container.
Clump forming houseplants like ferns, snake plants and African violets can be moved into a larger pot or divided into several new plants. Remove the plant from its original pot. Carefully divide the crowns by teasing apart the roots. You may need to enlist the help of a sharp knife for some. Divide so each new plant has a decent root system and top growth.
Plant each division in a container slightly larger than the remaining root system and at the same depth as before. Be sure to water thoroughly to remove any air pockets. Add additional potting mix, if needed.
A bit more information: Move recently transplanted houseplants to a bright location out of direct sunlight. Water thoroughly as needed. In a week or two, move them back to their permanent location.
