Pure leaf mould is the finest garden compost. It takes up to two years to make the perfect batch but it makes the best and longest-lasting mulch, and can also be used as an ingredient in home-made potting compost. Leaves are rotted by a combination of fungal moulds and microbes that need air and moisture to do their work, so make the heap open at the sides and moist before covering with landscape fabric to weight it down and keep the heat in.
