Farm Shares (CSA)

Farm shares (CSA)

The Conservation Foundation’s Green Earth Harvest CSA is an all-organic farming operation that provides healthy, organic vegetables to the community through the sale of “shares”. When you become a Green Earth Harvest CSA shareholder, you are essentially purchasing a portion of the harvest. You’ll come to McDonald Farm in Naperville (or one of our remote pickup locations) every week or every other week and pick up your produce.

As the vegetables mature and come up for harvest, there are typically 8-10 different crops available to choose from each week in your share. The list of contents changes through the year, based on which crops are in season.

We offer two share sizes- Personal and Standard Size. A Standard Size share is generally suitable for a family of 4. Our personal Size share is intended for smaller households. We also offer the opportunity to cheese weekly or biweekly pickups, meaning you can come every week or every other week. Some customers split their share with a friend as well.

mutual benefit of a csa

We strive to prove an appealing and ample supply of vegetables each week but since nature has no guarantees we cannot offer any either. The price of the shares is the value we strive to provide, however we cannot account for what impacts the weather or other events will have on our harvests throughout the year. We benefit from you paying up front, and you benefit from the harvest, which is why the CSA models works. You will be experiencing the ups and downs of farming and this will be reflected in your share.

To help keep the farm financially sustainable, we often utilize other revenue sources. Our intentions are to grow enough produce to amply satisfy our shareholders as well as additional sales to shareholders, restaurants, and the public. It is important for us to note that we never let these other enterprise opportunities encroach on our Shareholders and their weekly (or biweekly) vegetable pickups. We always put our shareholders first when considering outside sales opportunities.
