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. :)
We will be working on a small compost pile in the near future and plan to make a larger one in an area that we have been burning (about a 10'x10' area) downed limbs and debris (natural debris like leaves, tree stumps etc) and will use the ash from that to mix in with the compost. I totally agree about the lack of mature piles... We didn't have one last year so we were "outsourcing" our nutrients (buying heaps of compost at the local nursery). We did make barrels of compost tea which the plants loved!
Very much looking forward to having our own system going with the compost! :)
