I'm in Camas, on a 0.7
acre suburban lot, with a 10 year old food forest (ongoing) in my 0.5 acre backyard. I'm not looking for a homestead, but when you get to that point, I'd be interested in sharing plant material,
local knowledge, and/or trading surplus. I have about 200 varieties of edible
perennial plants (e.g. 54 varieties of apples), and most of them are mature
enough to produce.
My main goal was to be able to harvest something from my food forest any day of the year, and I am close to that goal. What I didn't think about was whether I would have time to harvest all of it, and
the answer is no (I also have a full time job). I think in order for
permaculture to thrive in a suburban environment, there needs to be some kind of system to facilitate trading of unharvested surplus. I haven't figured that out yet though.
