HAHAH yah, I personally like to let mine hang into August before plucking any. Anything hanging into Sept normally gets clobbered by the animals.
But, this will be the first year in many that I'll get a full harvest on my younger keitt, which regularly dumped 95%+ of its crop due to that black spot gunk. Nordox monthly knocked it out. So far only 2 mangoes out of hundreds lost to black spot. The rest are clean.
You need to tell walter to buy some Nordox :-). Nice thing is that it resists rain washing, so a once per month spray regimen is sufficient, even in the rainy summer. It's also OMRI listed and a caution (vs warning or danger) label. Bye bye black spot :-).
Keitt can actually be ripened well when picked very early. Surprisingly, they develop full flavor when picked early. Our neighbor picks their entire multi-hundred pound crop around this time every year. Their tree is currently wiped clean :-).
Let us know how it ripens. I haven't picked any of ours yet, so I'm curious.
Not ripening at two East PBC locations. Again, stem end rot/internal breakdown instead of ripening. Also, keep in mind, Nancy is further North in a colder area where things got going later and slower to progress.
Why on earth would your neighbor strip their tree at this time? To each their own I guess....
