My garden floor seems like dust covered concrete as its a new build and not really suitable to grow in - especially as it seems to have been filled with old bits of brick and everyting else.
i would like to make raised beds of varying heights for various fruit and veg.
Was thinking of using scaffolding planks - would these be OK. I though they might rot too much but wondered if they can be covered with some waterproof material that also covers the ground with holes in the bottom for drainage.
For carrots etc I would use 2 high on their edge held together by some kind of metal brace (i can picture it in my head - words may not be clear though!).
If this is wrong, do you have any other ideas? I have seen some plastic quick-lock type ones which are stackable but they are quite expensive.
