Keeping oysters in cages allows them maximum exposure to oxygen and plankton, which means they will grow faster than they would in their natural habitat on the Bay bottom. You then tend these oysters for about nine months. New gardeners are required to attend a training session, from which you will leave with everything you need to grow oysters, including cages and about 1,000 to 2,000 spat (baby oysters). Once grown, the adult oysters are returned to the Chesapeake Bay Foundation for planting on sanctuary reefs. The Chesapeake Bay Foundation's oyster gardening program gives people the opportunity to help bring back this vital species by growing oysters alongside their docks.
