South Floridian here. We have 2 varieties of avocado, 2 of mango, 2 of coconut (6 trees in total), blood orange, lemon and grapefruit. When they’re in season there is too much fruit to even give away, since many neighbors have some of the same growing as well. I use stake fertilizer twice a year on the citrus and keep them mulched as they’re still a bit small. The others are well established and take no maintenance other than occasional pruning.

Something is up with my avocados though. They were great producers for years (one is quite old, probably 60+ years, the other is probably in its 30s but not sure), but these past two years there have been so many blooms but almost no fruit. So you get the downsides of massive “rains” of pollen when there’s a slight breeze, but none of the upside of free avocados :/

I also have about 2 dozen pineapple tops that have been propagated and planted. Many of them are pretty young, but we get around 3-4 teeny-tiny pineapples per year. Again no maintenance once they’re going (I usually propagate them in water until the roots are a good 6-8" long before putting them in the ground).

I’m thinking about adding a banana shrub, but have also thought about sugar cane since then between that, (once I learn how to process and distill it) the coconuts and the pineapples I could realize my life-long dream of making a fully home-grown piña colada.
