When would be the best time to divide 'Autumn Joy' sedum?
Early spring is the best time to divide ‘Autumn Joy’ and other upright, clump-forming varieties. Dig up plants in early spring just as new growth begins to appear. Divide each clump into sections with a sharp knife. Each division should contain several shoots and a portion of the root system. Replant the divisions immediately. Sedums perform best in well-drained soils in full sun.
