Expensive gardening mistake - help needed
Firstly this looks like a great place to learn about gardening and gets lots of help and advice I have to say that I am not much of a gardener, a few pots are about my limit. I like the idea of it but the reality tends to be all together something different - lol!
Anyways, I need some advice please about what to do to rectify a problem. I have a piece of ground that backs onto the driveway. There was a flat bit that sloped away from the drive. It was turfed. However, the builders dumped a load of soil and rubble on it from making a new patio and in my madness I decided to try and turn it into a sort of raised bed. I laid more soil - 4 tons of it in fact - on top of the builders mess and then shaped it so that there was a bank of earth in the middle and a flatish bit around the outside. I had planned to put in wooden borders where it sloped away ( to stop the gravel slipping down ) and then after planting up with wildlife friendly plants I was going to cover it all with gravel and rocks and driftwood, etc. The problem I have now is that the wooden borders cannot be knocked into the soil as its just loose, so nothing to actually hold them in place. The 4 extra tons I added has made it too deep to reach the solid earth underneath and when you do get to the solid earth its actually hard packed gravel and rock.. And because the soil is just loose it is starting to slip down the slope when it rains. Its difficult to describe it all, pictures would be far better, but I don't know how to add them here.
So if anyone can understand my slightly incoherent ramblings and offer some advice I would be most grateful Ijust need a way to secure the wooden borders at the top of the slope.
