When I moved to my current location, there were six trees on my 0.67a lot. There was a Cabbage Palm, two Laurel Oaks, two Queen Palms, and a Bauhinia (Hong Kong Orchid tree). One Oak was struck by lightning and died, and one Queen Palm snapped in half during Ian. I'm slowly trying to kill the Bauhinia.
At last count, amongst all the fruit and "ornamental" stuff I've planted, I've planted 30 types of native trees and shrubs, as well as some native flowers. So far, everything, once established, has not required any watering, which is great, because my only means of watering is a hose, but mostly me wandering around with a watering can. I collect whatever rain water I can, and that mostly gets used on my out-of-control potted plant collection.
I have no idea what it's like to run a farm, but from what I've noticed, stuff in my yard doesn't need much/any input to grow and fruit. I've done pretty much nothing since post-Ian cleanup, and I had a great Mango, Papaya, and Suriname Cherry season, and presently my Barbados Cherries, Calamondin, Natal Plums, and Papayas are loaded with fruit. Hoping for no freezes (but temps low enough to put the Sri Lankan Weevil population in check), and I'll be anticipating an even better Mango Season.

Timbogrow, thanks for the suggestion in dealing with Sri Lankan Weevils😂. I've just been dropping them into a cup of soapy water. This is from my first night of "collecting":

Here's to growing naturally in FLA!
