Really can't beat the no dig gardening method and have watched and followed charles dowding for many years. You hardly have to water, very few weeds and its just a joy. However last year I did my compost top up using horse manure and its the worst thing i've ever done. Got to cardboard the whole patch and buy in some mushroom compost for next season. I've not got a large area of the garden as veg, so only really do Lettuce, Brassica, Sweet Corn, Runner Beans, onions and Spring Onions, but I do always get a nice tasty crop of a variety you will never find in the supermarket. In the Greenhouses, it tomatoes, cucumber and peppers... the same as everyone else!
