When you need a prolific filler plant that will grow easily and vibrantly in a sunny area, consider planting sedum. Because sedum tolerates dry conditions and average soils, many gardeners successfully grow sedum in home landscapes. Keep your sedum plants healthy by dividing sedum every three to four years in the early spring. As you divide your sedum, spread it to new planting areas in your landscape.
Spread the tarp near the area where the sedum is growing.
Insert the shovel into the soil approximately 4 inches outside of the outer perimeter of the sedum plant. Push the shovel into the soil to dig down deeply beneath the roots of the sedum. Continue repositioning the shovel around the sedum to dig the entire plant from the soil, taking care not to damage or disturb the root clump.
Place the sedum plant directly onto the tarp where you will divide it. Examine the sedum plant as you prepare to divide it and cut away any portions of the root clump that appear unhealthy. Discard these parts of the plant. Divide the plant into smaller sections measuring approximately 4 to 6 inches across the crown, using either the sharp knife or by pushing the shovel down through the crown of the plant.
Prepare a new planting area for the sedum. Cultivate the soil with the garden spade down to a depth of approximately 4 inches. Dig holes for the sedum that will enable them to be at the same depth as they were previously growing. Space the holes 10 to 12 inches apart.
Place the divided sedum plants into the prepared holes and fill soil in carefully around the roots of the plants so they are at the same depth as they were previously growing. Water the sedum plants generously immediately after you transplant them.
Pull up the tarp, discarding any plant and soil debris.
