More than a dozen farms in the Washington area have Community Supported Agriculture (CSA) programs. Customers pay an annual membership fee in advance to cover farm production costs. The farmer provides a "share" of the harvest -- a box of seasonal produce -- on a weekly basis for a predetermined number of weeks. On most farms, a full share is enough vegetables to feed a family of four (two adults, two children) or two vegetarians for one week. (Half shares are also available.)

There are variables. Some CSA farms are small family operations, while others are vegetable gardens maintained by private, nonprofit foundations. Crops vary from farm to farm. Some grow corn, some don't, for example. Most are certified organic or use organic farming methods.

Usually vegetables are picked up at the farm or, in some cases, at a delivery site convenient to the member's neighborhood. There are CSA farmers who deliver produce to homes. Prices vary. It's best to shop around for a farm that meets your needs. (We have included farms that are fully subscribed for the 2003 season for those who want to plan for 2004.)
