Magicians have wands, doctors scalpels and gardeners have mulching machines. Our spells improve soil by adding mulch, liberally, which imitates the effect of a forest floor. Rich humus forms under the mulch layer, improving the fertility, water retention and soil fauna biome. An environment which quickly attracts the masters of soil management: earthworms.
This is an organic method I favour as it also provides a way to return all the clippings, cuttings ,weeds and debris back to the garden.
Carbon return offsets the small carbon footprint we have and leads to a concious earth loving method of gardening.
