Sedum, also known as stonecrop, is a plant that produces succulent foliage and flowers in various colours. The plant is available in several varieties that reach a height of 6 to 24 inches and width of 12 to 24 inches. Propagate a mature sedum plant every three to four years by digging up the entire plant and root structure and splitting the root-ball into multiple sections. Sedum plants should be divided in the spring to prevent disruption of the fall blooming.

Disinfect all tools by washing them with a solution of 9 parts water and 1 part bleach. Let the tools dry prior to using. This will prevent the spread of diseases that are carried on tools.
Dig up the sedum plant, making sure to include the entire root-ball structure. Place the plant in a shady location to prevent the sun from drying it while you are separating the plant.
Inspect the root-ball to see which areas can be easily separated into new plant sections. Gently pull or cut the roots apart to divide the plant. Each section must have a root structure that includes two growth eyes and fibrous feeder roots.
Prepare the new planting location by mixing organic compost into the soil to increase the soil nutrient value and moisture retention.
Replant the divided sedum by digging a hole that is slightly wider than the new root-ball. Plant the divided plant at the same depth it was in the previous location.
Cut the stems to half their length to stimulate the plant to branch out and thicken.
Water the sedum immediately after planting to stimulate root growth. Continue to water the plant to keep the soil moist for two to three weeks.
Tips and warnings
- Divide sedum plants if the centre of the plant begins to die out. Split the healthy portions of the plant and root structure and discard the centre section.
