Wood preserving on a shed too close to a retaining wall

Hi,

I'm guessing there are no easy answers to this but I thought I'd look for ideas...

Last summer I had a wooden shed / workshop put up in my garden. It is about 14' long. My garden is on a slope and one side is next to a retaining wall. 7' gabion crate and 7' breeze block wall. I didn't give much thought to it but it is about 1 - 1.5 inches from the breeze block wall and 2 inches from the gabion crates. This gap is is full of muck and stones now and I'm struggling to clean it out. I tried a pressure washer and a thin pole (a fencing pin) and I've cleaned some of it out but it is pretty hard going and not 100% effective. I'm guessing I have no alternatives and need to carry on with this approach but I thought I'd check whether anyone had any magic suggestions !

Thanks.

 

Any chance of moving the shed away from the wall a little? At 1"-1.5" you'll have a tough time maintaining the paint on that portion of the shed. Another option might be to cover that opening with something that will direct the rain water and debris away from that opening.
