I currently have 5 grades for ease of flowering for mango in south Florida:. A few examples provided with each category. Some are disputable as to which group they belong but this is a rough projection based on recent past behavior. Stem age plays a major role as well, and I can’t emphasize enough that you want to get your pruning done before the end of August here to avoid late flushes of growth, and to avoid over feeding the trees to lessen the likelihood of that as well.
Grade 1/Very Easy : These are precocious, and frequently blooming before the New Year regardless of what kind of weather we see. Rosigold, Edward, Dwarf Hawaiian, Rosa
/Grade 2/Easy : these can achieve decent blooms off less than a week below 60F depending on the age of their stems. A solid week will make most of them achieve majority blooms.
Angie, Pickering, Ah Ping, Jean Ellen, Ice Cream, Super Julie
Grade 3/ Medium some bloom after a week or less but not majority of canopy depending on stem age. 10 days with lows below 60F is typically enough to get a majority bloom.
Haden, Bailey’s Marvel, Glenn, most Thai mangos and most old Florida varieties
Grade 4/ Difficult Will flower inconsistently unless they receive multi-week cold fronts. Usually very unprecocious. Sweet Tart, Alphonso, Mulgoba, Peach Cobbler, Bombay
Grade 5/ Extremely Difficult/ Near Impossible These likely require 2+ weeks *untinterupted* lows in the 50s/40s plus optimal stem age and 6+ years of total tree maturity to achieve full blooms here(growth flush needs to be hardened off before end of August and cold front must be January or later). In reality, Most winters here they’ll either fail to bloom completely or just throw a couple panicles here or there. Sindhri, Dasheri, Gilas, Anything from northern India or Pakistan.
Groups 3 and 4 are the problem for people in Palm Beach, Broward, and Miami-Dade, and maybe even the Treasure Coast now too. Due to a lot of trees in the nursery trade being in those categories.
On the other hand, trees in group 4 and 5 should do well in California and some group 4 maybe central /West Florida
