Sedum Brilliant (Stonecrop) ground cover grow best in well-drained soil. These low maintenance plants need little care, should they start to flop in the middle of the plant you could cut back one in three stems to the ground in late May to encourage new growth and keep them bushy. Sedums prefer a sunny spot and well-drained soil – they are drought tolerant so don’t need much watering once established. If growing them in a pot, incorporate some grit into the compost to ensure good drainage.
As a rough guide when planting Sedum as ground cover – 4 plants per square metre is adequate with a little patience, 6 will give better coverage, and 9-12 will make a weed supressing carpet very quickly.
