There is no guarantee with a CSA.  Blight, bugs, weather can all wreak havoc among a crop.  But, if it works out well— it’s amazing… organic fresh veggies that are so fresh and delicious.  It’s the chance you take same as the farmer. 

Check out the farm or call them.  Talk with the farmer.  See if there’s a waiting list.  See if there’s a discount if you put in some time weeding and harvesting.  (Mine gives $100 off if we put in 12 hours of work and it included website help)

A farmer’s markets might work better for you— but make sure you go regularly.  This way you’re paying for what you buy at the time.  Then there are those that even let you buy a share at the beginning of the year then select what you want when you come to pick up.
