How big a garden does one need for frugal times?

[Grasswire2]

7. I'm filling my freezer space from the farmers market.

As things come to market, I do what my grandmother did. Berries of all kinds, cherries pitted for pies, peaches, rhubarb, tomatoes from my garden....all are gathering in my freezer. (Just a modest size freezer space at top of my fridge.) I've made a dozen quarts of refrigerator dill pickles, and have Gravenstein apples for making apple butter and pies soon. Will be getting lots more apples. The eating apple we like best is a variety called "Crimson Crisp" -- it is sooooo delicious and lasts very well in the fridge for many months. I also like "Spitzenberg" as a keeper. Good flavor. I had some last until March over the winter in the bottom drawer of the fridge.
