You didn't mention having a compost heap on the go, so I'm not sure whether this has been factored in yet? I only notice as I have a few piles that I am really, really hoping will be doing their jobs well enough that I can throw some lovely black gold onto my beds this coming winter, and build up the nutrients. This is one of the problems of beginning a garden - the lack of mature piles at the ready.

I can't wait to see how you design your new garden. :)
