Cutting Back Sedum Plants
When and how do I cut back my 3 ft. sedum plants in the fall?

Wait until after the first frost and then cut the plant back to about a couple inches. Apply a fair amount of straw mulch to keep it well protected over winter. You can also choose to leave your sedum plants alone until spring (trimming back the same amount), allowing the foliage to provide the plant with winter protection.
