There are some things that simply won't grow in northern climates without a greenhouse. Citrus, for example. You can do a dwarf tree in the house perhaps..one of those small lemons or limes.
We're pretty close to raising our food. The rabbits and chickens could all provide meat/eggs using hay/grains/greens that we grow or get from next door neighbor farmer. I still buy the grains from the feedmill, but since that's the same as buying from the farmer, I don't care
) Garden veggies I've got covered. As well as plums and apples from our land.
The greenhouse is being built this summer if I have to do it all myself. Going to try for lots of greens for the rabbits, as well as a few "treats" for us.
Lots of garden veggies store well in a root cellar, which can be as simple as a barrel buried in the ground.
Lately it's been kind of a game trying to figure out WHAT I can produce that will last into the winter without canning them. So far I have Pumpkins, potatoes, squash, carrots, turnips, parsnips, apples, onions, beets. (as well as the garlic, etc.)
I'm going to try to grow a fig tree this year.
oh my. what a thread drift!
