CSA stands for community-supported agriculture. CSAs are subscription programs in which you pay upfront for a weekly, bi-weekly, or monthly share of the farm's produce. This provides the farm with funds early on in the season when there are a lot of expenses but not a lot of sales, and it provides the customer with a steady supply of fresh produce that can be counted on throughout the season. CSAs are a great way to build a relationship with a local farm and to adjust your purchasing habits toward food and flowers that are truly local, fresh, and in-season.
