Hi, we have a small area of 60 degree sloping bank, topped by a thirsty beech hedge. The soil is bone dry. Weeds thrive there though! We’re too old now to clamber up there, strim it or anything so we want to cover it with coir matting maybe, or something to stabilise it, and after adding manure perhaps, and then form a green bank of sedum or similar. Low maintenance anyway. It’s only 7foot x 8 foot. Any suggestions how to stabilise first please?
