Sedum is a versatile bedding or border perennial that makes itself at home in rock gardens, flowerbeds and containers. There are many sedum varieties, all having the distinctive thick leaves with a range of blossom colors. Sedums are succulents and, therefore, desire a well-draining soil in a sunny location. Once sedums are established, a gardener's work is mostly to just enjoy the beauty of these perennial plants. Prune sedums lightly in the spring and watch them grow all summer long.
Leave the seedpods and spent blossoms on the sedum plant throughout the autumn and winter. This will not harm the sedum and provides visual interest over the winter. Birds enjoy the seeds as well and will often perch on the sedum branches to peck at the seedpods.
Watch for new growth and new shoots in the early spring. This is your signal that it is time to clean up the sedum plants for the upcoming growing season.
Trim off all of the old blossoms and seedpods. Shape the sedum plants as desired to train them to grow how you want them to grow.
Monitor the sedum plants as they progress through the growing season. If they begin to appear unbalanced and overgrown in the center, cut these overgrown portions back by as much as half to encourage more attractive blooms from the sedum plants.
