My two trees, a Cogshall and a Pickering, both started sending up pannicles a month or so earlier than usual. The Cogshall shows half a tree in bloom and the other half mostly dormant. The Pickering has about 25 to 30 percent blooms scattered throughout the tree. Both trees appear to be done pushing pannicles. What might be the cause of such sporadic production?
A week or so of Cold weather at the beginning of December. Full blooms on all trees (in Florida) require about 2 consecutive weeks of nighttime temps below 60F. With less of that, there is progressively less complete bloom.E.g. ,arbitrary numbers: 10 days of 50s might result in 90% bloom7 days 60%5 days lessAnd so forth.Some trees had full blooms off the early December chill (mostly older large trees and “bloom sensitive” cultivars, with exceptions of course).Since then we’ve largely been above historical average on nighttime lows in our typical pattern over the last 10 years or so. So the mangos are staying dormant until another major cold front rolls through that lasts the better part of a week instead of just a couple nights.
Fruit set on glenn, coco cream, ndm4, kesar, orange sherbet, sweet tart, and kasturi. second round of blooms shooting out on kesar.its still early
Hey Alex,Which cultivars are "bloom sensitive"? It'd be nice to know this information considering the global warming trends.

It'd be nice to know this information considering the global warming trends.I probably need to make a list. Just off the top of my head Edward and Rosa are a couple examples on the extreme end of trees that will throw bloom off marginal stimulus. Then there are varieties like Florigon or Graham that can flower fairly completely off of a week of cool nights, as opposed to the nearly two weeks required by some to achieve that.Also keep in mind that some of it could be issues with precocity (or lack there of). I was doing some consulting work for another grower a couple weeks ago, and his large Sweet Tart trees were mostly flowering pretty well. But his trees are both larger and located in a cooler location west-ward. A few degrees can make an enormous difference.

Would you know if any of the following bloom easily:Fruit punch, jakarta, ice cream, dwarf hawaiian, angie, cotton candy, phoenix, pineapple pleasure, sugar loaf, kesar
