Community supported agriculture lets people subscribe to a farm for a season, receiving a weekly basket of produce.
Most CSAs ask that members pay for the season upfront, but some accept weekly or monthly payments. Some require that members work a small number of hours on the farm during growing season, and some trade the fresh produce in exchange for help with harvesting or deliveries.
CSA seasons typically run from late spring through early fall. According to localharvest.org, the number of CSAs in the U.S. was estimated at 50 in 1990 and has since grown to more than 1,000.
To find a CSA program in your area, visit localharvest.org/csa/ and type in your Zip code.
