Since not all the leaves are brown, you should be able to determine if it was sunburn or from something in the spray by remembering about where the sun was when you sprayed, and noticing which leaves are most burned, and how they would have been oriented towards the sun at that time...

I did spray it everywhere even the non affacted area :-(

Gary, post some pics of your trees. I'd love to see

drscifi, are leaves which were not so exposed to the sun also burned? Actually, I need to take some more pics, I want to get some of my different mangos in flower, which most are right now. I'm real happy since I replaced some of my mango trees which have had problems since Frances/Jeanne four years ago. Replaced with asian mango vars, which all look great (so far).

Like wise Gary, since those hurricanes, my trees stop producing. I guess it was the streess. This is the first time they are fruiting. I am so exited. I would really love to see how your trees look now. It didnt see to make much of a diff. They were all burned and most started falling. I did my moms tree later during the day, like at dawn and nothing happend. so this must be sun burn like you said. My other tree the haden which had just one branch with fungus and the rest healthy, I sprayed only the affected area and nothing happened. No burns. Those darn little leaf notchers are pissing me of though. I would love to kill them, but can't since I would also kill the polinators. Gary, behind my shed is a bee hive. I left it alone since they never really bothered me and I figured I would leave them so they can fertilize my mango tree when the time is right. It's been a little over a year, and the other day I was looking at the flowers on one of my mango tree, and t was the best site ever! The bees where on that tree doing there thing with the flower. I was so happy. I tried to take a picture with my phone, but the bee didnt appear. Please post you pics.

Ar eyou also in zone 10?

I'm in around 10A or 9B, south Brevard county, within a mile of the intracoastal waterway. I'll be off in a few days, might take some pics then. I will be doing beekeeping in a couple months, looking forward to that new endeavor. You're lucky to get a hive without even trying :)

Does anybody know how to graft mango plants. I have some special plants from asia grown from seeds and the plants are about 4'00 tall. I have been told that it will take 12 to 15 years for the trees to bear fruit unless they are grafted. If grafted they will start to bear fruit in 2-3 years. If you know of any nurseries who might be able to help me graft these plants it will be greatly appreciated. I am in Orlando FL.
Thanks

I think they might mean grafted plants with scions from mature trees. Grafting a plant with bud wood from a seedling will only give you a plant that is grafted but basically the same age as the seedling.

It might make a difference if you were to graft it onto a mature tree.
Just my thoughts.

It sounds like to have great rootstocks. If it were me, I would go to a local nursery and buy a small tree of your favorite grafted variety and graft all of the branches onto your seedlings. That way use will be able to get a few nice grafted trees as well as still having the one you purchased. My favorites are Glenn, Mallika, Julie, Nam doc mai. The absolute best IMO is the Champagne mango, but after a year of trying I have pretty much given up on finding one. Have you checked out Pine Island nurseries site? There are quite a few sites that show how to graft them. I'll attach a link for you. If you try it just make sure both the rootstock and scion are in a growing phase.

Here is a link that might be useful: grafting link

I need the description of the Gary mango variety
