Autumn joy sedum is a hardy succulent ideal for poor growing conditions, including hot sunlight, drought and thin, rocky soil. An unusually tall sedum, autumn joy will grow to 18 to 36 inches. In early autumn when most flowers have faded, the autumn joy will burst out with clusters of flowers that start out pink, turning to bronze and then to a bright, coppery red. To maintain vigorous plants, divide autumn joy sedum every three to five years.
Prepare the planting area for the transplants ahead of time so the roots won't have time to dry out when you divide the autumn joy sedum. Choose a well-drained spot in full sunlight. Although autumn joy sedum will grow in poor soil, it's important that the soil drains well. If puddles remain in the planting area for more than four hours after a rainfall, choose a different location.
Divide autumn joy sedum in the spring, as soon as new growth emerges. Water the autumn joy sedum lightly the day before you plan to divide them.
Use garden shears to trim the foliage down to 5 to 6 inches from the ground. This will allow the divided sedum to root easily, and will prevent moisture loss through the leaves.
Dig in a circle 4 to 6 inches from the autumn joy sedum plant, using a garden fork. Rock the garden fork back and forth to loosen the roots, then lift the autumn joy sedum plant carefully from the ground.
Shake the autumn joy sedum gently to remove excess dirt. Pull the plant apart into smaller sections. Be sure every section has several roots.
Plant the divisions in the prepared soil immediately and tamp the soil down around the roots. The autumn joy sedum should be planted at the same soil level as it was previously. Keep the soil slightly moist until new growth appears, but be careful not to let the soil get soggy.
For the best chance of success, divide autumn joy sedum on a cool, overcast day.
Like all succulents, autumn joy sedum is susceptible to root rot if the soil is too soggy.
