Hi everyone I am new to this forum we are mango farmers from Saudi Arabia and we have a farm of 5k mango trees and 3.8k are productive trees most of the trees are 20 years old and more only few hundreds are less than 15 years

now most of the trees are over 15 meters some more and some less now in the harvest season I am facing a lot of problems because ripen mango are falling to the ground and getting damages cause of the height.

now I am willing to prune the trees but in few rounds like 500-1000 trees a year so I don not kill the farm productivity

just need some advice how to prune and if some one have a good guide with pics will be awesome.

thanks
