As perennials are cut down to the ground in Autumn when they die back what is the best way to apply mulch please? Do you, for example, cover the crown as well as the area around where the roots are underground, and is this with about 5 to 8cms of the mulch? If so, do you need to remember to pull back that mulch cover in Spring to allow in light to the centre to allow leaf growth?...or will the mulch roof have gradually eased its way back into the soil? If not, will the plant simply grow up through it? If so, what will the bed look like after, say 6 winters???!!! TY,P.
