Share sizes vary. Conventional wisdom is that a full share provides enough produce to feed a family of four for one week. Half shares and mini shares are available. The language of sizing can differ among farms, so ask before you make your decision.
Another thing to consider: How pickup works. Most CSAs have their members collect shares at fixed points, such as farmers markets, schools or stores. Others offer delivery, included in the price of the share or as an added fee. As you compare your options, take into account the cost of gas or your time.
These farms still had shares for sale as of the end of January. Many sell out, so sign up early.
The farms are listed according to the state in which they are located. To search for CSAs by pickup location, check out our interactive map.
