Hmm. In general I've noticed with mango that our seasons seem to be about 3 months earlier than yours there, and that would be consistent with our Choquette flowering starting in December and Alex saying Choquette there starts now. Our Pollock is just starting now but that could be because it's a top work graft that's just a year old so it might be off its regular schedule. I also have a top worked Oro Negro bigger than the Pollock and a grafted Oro Negro in the ground 2 years that aren't showing any signs of flowering, which seems weird. Our Catalina planted the same time as the ON has a mixed bloom. The Kampong I have is a top work and shows no sign of flowering yet. Our only super established tree is the Choquette which is enormous, so it may be the only one on a regular schedule.
I wonder how much elevation affects season?
