Notching a mango tree to encourage branching.
Hello, I bought a few mango trees in an attempt to grow them in Northern California. Of my collection, I have two that are rather tall (almost 4 ft.) and I would like them to branch out lower but I don't want to prune them down if there is a chance I don't need to. I read about "notching" (slicing into the cambium to either block hormones and or cause nutrients to pool at the would be bud site; where you want to branch) that some growers use to get apple and pear trees to produce lower branches. I wanted to know if anyone here has ever done this or if it even possible with mango trees?
