I would like to do this but OH wont let me. We have only a tiny back yard garden. A penalty of London. That is why I had an allotment.I have composted manure AND other green/brown waste since 2017, it's called manure when it is fresh. The middle of my old heap is black and loamy just like the compost that comes out of bags you buy and it is full of nutrients.
But the thing is Jessey, in about March you have to dig your patch with a spade and dig in the compost. It aerates the soil too.
And what comes up depends on the soil type - Is it clay or loam or sand etc and how well drained. My daughter has a sandy hill top garden a short walk from us and very little she grows ever does well.
