My garden beds are ground level, and because of age and a bad back, I would
like to build/make higher ones.

It has been suggested to me to make the back wall of the beds out from the
fences in case in the future, the palings needs to come out, then it will
make life easier to work on the fencing.

I intend to make the walls of these beds out of bricks. How far away from
the fences would you suggest to come out.

Thanks for your help
Katherine
