Sedums are fairly light feeders.
Cut upright types to the ground after fall frost or before new growth begins in spring.
Never exceed the manufacturers recommended rate.
This might also be good to know should you be required to comply with particularly strict local environmental regulations.
Addition to plant stimulation it also contributes to soil improvement ensuring a balanced substrate layer.
Apart from the economic incentive for selecting a diverse pallet of sedums for the roof it also has ecological effects as a resilient roof will require less fertilizer applied as well as fewer pesticides.
It provides a strong root system for the sedum plants and thus increases plant health.
