Leaves are our main source of humus for the garden. We could easily get manure, but we prefer not to as we are on limestone, and apparently this type of rock filters ground water very little. We are afraid we would pollute our well which is very close to the garden. In many agricultural areas in Ontario, because of the spreading of manure, water from some wells is undrinkable, because it is too high in nitrogen. Our well water pass tests with flying colours and to make sure it stays that way, we only use leaves and leaf mold as soil amendment.
