Have recently acquired a North facing back garden 24 mtrs length x 23 mtrs width. No trees. Normal sized 1 storey house. Garden slops away downwards from the house onto large uncultivated land which is a further 6ft drop. Have not yet experienced what is in the garden: it is rather overgrown. Path feels slippery. Looks like might have had raspberries. So far have only read negative reports about North facing gardens. I like flowers & veg in particular & lots of both. Any suggestions please?
