I don't know much about gardening. My folks aren't officially "preppers," but they grow a pretty nice garden near a Florida Beach. They have a compost pile and use that to enrich the soil. When I was young, they also went to a stable and got a pickup truck load of manure and sawdust. (Don't ask who had to crawl in the back of the truck and secure the truck top. Grrr...

) They have a heat pump furnace and well and big rainwater collection buckets for a water supply.
They definitely rely on the agricultural extension service and plant nurseries for advice. They grow greens (collards, mustard, etc.), lettuce, butter beans, corn, tomatoes, satsuma oranges, grapefruit, and they have a wild banana tree. Fig trees grow way too well in their yard. They are pretty close to self-sufficient in produce with a fairly small garden. Good luck! You can do it!
