In Sonoma County, the community supported agriculture (CSA) programs are thriving, but in order to keep subscribers coming back, farmers are providing more choices, including box sizes and delivery options.
That’s good news for consumers, who may be afraid of getting too much or wasting veggies they don’t like. Some farms will let you pick up a box every other week, while others let you trade out veggies at the farm.
There are also a growing number of meat and poultry CSAs, with options for folks who don’t have an extra freezer for that half cow share. A fruit farm membership also allows you to “pick your own” throughout the harvest season.
If you’re thinking about joining a CSA, it pays to do a little research to make sure you find one that fits your eating habits, lifestyle, budget and food philosophy.


The whole idea behind a CSA is to create a community of supporters who pay for shares of fresh food in advance. This model allows the farmers to nurture a closer connection to customers and ensure a steady market for their crops. For consumers, it provides peace of mind about food choices and perks such as potlucks and u-pick flowers.
Most of all, the CSA gives subscribers a strong connection to a family farm and the knowledge that they are keeping agriculture alive.
“Agriculture is not going to survive in Sonoma County if we don’t have the support of our residents,” said Jennifer Branham, co-owner of Laguna Farm in Sebastopol. “That’s the bottom line.”
Editor’s note: Laguna Farm ended its CSA program in 2021.

If you want to subscribe to a CSA, first make sure it is local. Some source from farms in the Central Valley or as far away as Mexico. That’s one of the reason Deborah Walton of Petaluma’s Canvas Ranch discontinued her CSA program.
“I tell people to always ask not who grew it, but where did it come out of the ground,” she said.
Most of the local family farms grow more or less the same seasonal produce and provide a weekly newsletter with recipes and tips. Choose a farm that’s close to your flight path. Then ask for a list of what has been provided in the past month. Consider what “add-ons” are available and whether the CSA operates year-round.
Most farms offer delivery to drop-off points, but some charge extra. If you do not have time to pick up a box, choose a farm that does home delivery.

Here is a list of a dozen CSA programs in the county, and what they offer:
Vegetable CSA Boxes
Open Field Farm, Petaluma: In 2012, Seth and Sarah James bought a former dairy on Spring Hill Road and turned it into a vegetable, berry, grain, egg and grass-fed Corriente beef farm that sells to CSA members only.
