I received a response in regards to my correspondence with Society of St. Andrew.

Hi Brian-
Thanks for your interest in gleaning opportunities with Society of St.
Andrew in the Jacksonville area.
We will be gearing up for our season which starts in November and goes
through June. We begin with “backyard citrus” trees that are offering
by homeowners across Duval County, and move on to field crops like
broccoli and cabbage in April and May and finish with potatoes in June
and July. The fields are located around Hastings, which is a small
town that lies between St. Augustine and Palatka on CR207.
I’ll send an e-mail outlining volunteer opportunities around the first
of November!
Sandi Newman
Area coordinator

Look for more updates to come!
