Hi Don
You write that “growing a green manure is never going to provide you with sufficient compost to cover your needs. You simply have to use large quanties of other materials, leaves, paper, vegetable waste, grass clippings, etc, etc.”
As the saying goes, “never say never”. The two gardeners I have referenced, Pete and Nick, seem to have done just that and, in theory, if we used the whole of a spare plot for green manure, we could start an export business!
I am at the early stages of my experiments with green manure and, following Charles’ advice and that of Nick Pawson, I have used a ‘starter pack’ of fym on my new plot, Plot 248. Last year I composted everything from my first plot, Plot 250, (minimal green manure) as well as fruit and veg waste from home, and my heap has generated some but not nearly enough good compost. With dedicated growing of green manure on Plot 248 I am hopeful that I will get sufficient compost for my needs.
