This is awesome to see and gives me hope! We have many of the same varieties! I am in the Upper Keys, also growing organically, and have now some 100 varieties of fruit tree/plant. However, this is just my first year so most of my plants are still small, not much too look at yet. Many got wiped out by some kind of sap-sucking blight that one plant brought in before I was able to stop it with a Rosemary oil and soap mix, there were problems with snails until I added Sluggo, there were spider mites until I got those, baby iguanas ate everything they could find for a while... so there have been a lot of different adjustments to be made and new things to learn. I also have rats and have to catch them and transport them North of here. It is a ton of work! But I'm so happy to see most of the plants have finally found their footing and are starting to do well. As of yet, the soil PH does not seem to be a problem - I guess I amended it enough. It will take me a few more years before I really have everything in hand and things are stable - I really hope we don't have a hurricane or bad tropical storm to wipe them out before they get stronger! I too am in a below-flood area, although my yard has so many trees it has a fair amount of wind protection (but not necessarily for 100mph!).
I was surprised to find yesterday that my Maha Chanok mango has its very first flowers! I didn't realize this would occur in winter... I don't see anything on my Mallika though. Every day is a new adventure with so many plants I've never seen before in my life up to now. Can't wait to get hopefully some fruit this year from some of them!
