Nottinghamshire, United Kingdom
I bought my first house in the summer, and with it inherited a unusually large (for the area) but alas heavily concreted garden. There are numerous flat beds and raised beds, but the raised ones are full of ornatmental stones. I would like to grow vegetables in one of these beds, but am not sure of how feasable this is. The bed is made of concrete pillars and sides and full of the following, from top to bottom: limestone chippings, a black membrane, sand, a mixture of broken slabs, bits of brick, lumps on concrete etc. It was the last mix of rubbish that was unexpected, as I was hoping that once I took the stones off there would just be regular dirt underneath.
So, do I have to dig out all of the rubble before I can put soil in? Or can I put soil on top of the rubble? How deep does the soil have to be, and can I put it directly on top of the rubble.sand mixture?
