When you find an especially good deal, buy in large quantities and freeze. Organic broccoli may be affordable in summer, but it will cost you a small fortune in winter. The same goes for strawberries, cauliflower, and many seasonal vegetables. Or you can choose to buy the already-frozen version during the off season. Frozen fruits make for great treats in winter, and frozen vegetables are perfect for soups and stews. If you're handy in the kitchen, you can always learn food canning and drying for more alternatives.
Search for a Community Garden
A smaller variation of the CSA programs, they are usually cheaper but also offer a more limited selection of fruits and vegetables. Many allow you to work your own patch of land, while others let you pick up your boxes of produce once a week. No community garden in your area? Start one. Many land owners would let you work their land for a share of the harvest or a small fee. It doesn't hurt to ask. If you have a large backyard, you can certainly grow fruit trees without much effort. If you live in an apartment, you can at least grow herbs. Don't let your space limit you. To find a community garden in your area, check the Biodynamic Farming Association website or your local Yellow Pages. Many programs also advertise in bulletin boards in health food stores and supermarkets.
Pick Your Own
Not matter where you live, there's bound to be a farm within drivable distance. While many offer pick-your-own fruit (which can be a great way to spend a Sunday afternoon), many also sell organic produce either in their shops or at roadside stands.
