Hi CarlosS

According to Fairchild Botanical in Coral Gables, you tip the branches every 2 hand lengths (about 16") right above the "pedestal of leaves". He said he tips at length and not at season. Personally I would wait for day/night temps to not dip below 60s on avg.

Good advice above, but I have some questions?

What kind of mango is it?
Is it a seedling or grafted?
How big is it?
Do you intend it to stay small?

If your tree is 1 year old it probably doesn't have 16" branches? Which is a good size to tip them at.

If you don't have a "condo" sized mango I'd wait till it got some height. I have some year old seedlings that aren't anywhere near big enough (~3') to begin pruning them, and a recently bought lancetilla that's around 6' tall that I'm going to top at 7' and let it branch out from there so I can walk around it once it's in the ground.

Dr Campbell didn't specify what type of mango to do it on. I've seen grafted and seedling pruning done the same way. When he tipped that 1yr mango tree, he tipped to about "hip" level. From there it begins branching to the sides.

It took me a few times to thoroughly understand what he was saying in his video but repeatedly watching it as time and knowledge comes, you began to understand. In a nut shell, you have the power to "shape" your mango tree to your liking (tying down branches, pruning to keep a low canopy, etc)
