We are building on Dauphin Island (north side, protected water front) I'd like to put in some trees. The soil appears very sandy. Here is my list so far: Bald Cypress, Satsuma, Kumquat, Meyer Lemon, Rosemary (not a tree i realize), sweet bay and camellia. Any thoughts? Suggestions? I spend the winter months in the cold so the idea of citrus and other edibles is appealing. Thanks.
