I will probably be staying ~2 years.
Unfortunately with the way the economy has trended over the last 10 years I am unable to get work for much longer than 24 month stretches.
I tend to find an outlet for my gardening instincts in guerrilla gardening (I have left behind a trail of Dunstan Chestnut seedlings all the way down the east coast

). However this time we have a rental with some space. I am not so worried about seeing anything get to maturity. I get a kick out of leaving something useful behind.
Generally I have worked off a shoe-string budget. I may purchase a plant but strip it for cuttings. I currently have ~30 eastern blight resistant filberts. Would have been expensive to purchase but grown from the seed less than a meal out for the family (mind you it was very hard keeping the squirrels off them).
Something I have noticed about this land. Its very sandy, well drained. There are vetches everywhere, so presumably low in nitrogen. I don't think the land is very fertile.
I would love to have chickens, but this place is within the city limits. I grew up with hens and miss them dearly. Very social animals.
Sweet potato sounds a good idea, and I know it does well in this area. Never grown them though. I have heard people talk about growing them from "slips". Know anything about this?
