Thanks SO much for posting those pictures Jabo!! Kudos to you for having such great success growing them in TN, you deserve a huge pat on the back! Just amazing, and your hard work is paying off... Best of luck and may you have many mangoes to eat this year 
Thank you! The same to you also. Mango is such a good fruit I regret not buying more when I first started of collecting. Oh well, that just means getting more trees now!
Jaboticaba45: Your mango trees look amazing. And doubly impressive that they are flowering already. How warm do you keep the greenhouse in winter to get bloom this early?
Thank you! I let it go between 40-45 sometimes even lower. Seems counterintuitive, but as long as it's above freezing, it's ok to get cold temps (I know people who keep theirs at 55 out of fear the plants will die) This year it may have gone below that when it was super cold (maybe 35?). Other than that, not much. Normally they bloom later. I don't know what's happening. The mallika panicles are only 2 on the tree right now, and are just early ones. I suspect the main bulk will pop in a month or so. Still pretty early though. I guess downside is there are no bees, but not worried at all. Plenty of ants and others going around. I've never seen bees on mango flowers.
