When I moved in there was a sort of terrace thing in the back garden... a low wall bounding an area filled with gravel and a hideous crab apple tree plonked in the middle of it. I cut the tree down very soon after moving in and because I hated the gravel (coarse, grey granite) but couldn't be arsed to remove it I disguised it with grass. Obviously I can't mow it so I have to use a strimmer and I've got fed up with doing that so I decided to clear the whole thing out. I thought I'd just kill the grass with weedkiller then remove the gravel but what I didn't know was that under the gravel was a bloody great tarpaulin and the grass has managed to drill through it into the soil beneath. The tarp has, effectively, taken deep root and half a foot of earth comes with it when I try to pull it up, so I'm having to do it in little strips. My plan is to remove the wall, flatten the terrace down to the level of the lawn then grass it over properly, but what I want to know is... why the hell does anyone think a ton of grey stones in a garden is a good idea?
