Seems she had decent clean crops from:
Marlys
Hatcher
Juicy Peach
Sweet Tart
Angie
Pickering
Neil Petite (Never heard of this one)
I was shocked as to how many trees either had very low yields, like 2 or 3, or none. I guess I have this impression that most of ya'll in the central to south Florida area have "perfect" clime/soil/conditions for producing mangos and they should produce well most years. Seems you have many challenges like we do with fruit trees just different in scope.
Loxahatchee is one of the worst places in Florida that mangos can be grown "successfully" (using that word rather loosely here). Mangos do not fruit well under those conditions for a variety of reasons:
1. High humidity has a depressing affect on the trees ability to flower at all, especially when temperatures are less than ideal
2. trees are more likely to flush vegetative growth at the wrong time
3. Fungus is a big problem, both on the flowers and fruit. There are aggressive strains of anthracnose that thrive in Loxahatchee that make it virtually impossible to get fruit from certain cultivars, even if they are treated with a good fungicidal program. There is also foliar scab, a big problem with certain cvs like Angie and Keitt. This can severely limit growth and impact the overall health of the tree
4. In the vent that very cold weather actually does roll through, interior areas like Loxahatchee are much more likely to experience freezing or near freezing weather, which can ruin the crop some years and set the trees back.
What fruit that you do get invariably comes out filthy. Not just because of anthracnose either....fungi like scab, sooty blotch, and flyspeck are even bigger culprits. Those are practically unheard of where I am.
You'll notice all the oaks, pine and cabbage palms out there.....excessive vegetation, coupled with lots of bodies of fresh water (ponds, canals, etc), + distance from ocean breezes, higher rainfall totals and a loamier soil that contains more nitrogen and holds more moisture = the perfect storm of garbage to crush any mango growers dreams. I can only imagine what it will be like once MBBS and "the rot" becomes firmly established out there.
