North facing slope and heavily wooded looking for something that doesn't take much care... I would suggest looking into growing a patch of ginseng. It would take a bit of work to get the ground plowed ,shaped and planted but after that the maintenance is pretty minimal provided plant spacing is far apart. Mind you if you do plant that crop,don't tell anyone. Ginseng would take about 5-7 years to fully mature, after that you would have a pretty good income.
