The last paragraph of your comment sounds very very familiar... just what our plan is!
Regarding seeds - I save seeds from some of our vegetables, such as collards and kale, herb seeds etc. I discovered the hard way that seeds more than 1 year old often do not grow, and this also includes “boughten” seeds. Don’t count on old seeds.
Generally speaking, the smaller and softer the seed covering, the shorter the lifespan of that seed.
That is why you should test germinate your seed, before planting; even the tested seed successes can be transplanted into the garden.
Also, FReeper "Diana In Wisconsin" offers once a week gardening forum, generally on Saturdays to answer all your questions. Just Ping her .
