In autumn, the organic waste bins are full to bursting. And the compost, too, is frequently overflowing with large quantities of accumulated leaves. They cannot stay on the lawn, as the grass under them can suffocate and rot. And yet we can do quite a lot of things with foliage: they can act as frost protection for garden beds, or offer beneficial small animals a pleasant refuge for the winter. Leaves are an important raw material for the formation of humus.
