Rotting bed problem. HELP PLEASE!
It's a pity you can't just go and get materials, but perhaps in another month or so, that might be possible. You could always think about removing the plants at the front in preparation.
That would make life easier when you tackle the main structure, which I think you're going to have to do....
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
