Depending on the size of the garden, you can amend the soil to a large degree over 2 years to change it to what you'd like. I lived round about Apopka, FL for a few years. The soil there is sandy and you just need to lay out a few hay bales, or straw bales with some bulk triple shredded mulch that you can get in your pickup truck, or compost mixed with topsoil. The more organic matter the better, and let it break down. I was able to grow broccoli, cauliflower, lettuce, melons and plantains in FL as a boy.Cool... I’ve been looking into growing Christmas trees (in Florida) ... put in a few Leyland Cypress cause allot of the trees I know and love won’t grow in that hot humid sandy environment but cypress grows about 4 feet a year and in Florida. I also grow vegetables but there and again what grows in Florida? This is all predicated on my wife and giving her joy before anything happens and if I can do it, if God gives me the strength, I will. My own wish is to take my grandchildren to Church... there is a primitive Baptist one in Winter Garden that’s just lovely.
We've got a bunch of Christmas tree farms here in Ashe County, NC. Spruce and such cold weather trees. We hardly go over 80 degrees round here.
