planning a new vegetable garden... on gravel and grass
We're about to move into a new property and I would like to get in a vegetable garden right away. The property is mostly gravel and rock but at the front of the property is a pathetic, over grown lawn that has become almost entirely quack grass (no one has lived on the property for about 4 years). The soil goes about 3 inches down before it hits gravel/sand. What I'm tentatively planning to do is to lay down newspaper and have a load of aged manure brought to the property to have laid down on top of the newspaper so that it'll be about a foot thick. I haven't planned to roto-till the grass because of the gravel being so close to the surface. Does this sound like a decent plan or does it sound destined to failure?
