Pineislander and Orkine, thanks for the replies.
Using copper wire technique sounds like a good plan. I have some electric fence wire and could use that. If that doesn't work then I'd resort to pruning.
If I were to prune the tree, where should I prune it? Also, this tree has been pretty slow growing. I assume it is because that mallika is a slower grower...the rootstock is way bigger than the grafted part. If I prune back, I feel like it will take forever to get back into shape. Is it better to rip it out and plant a new mango? I'd hate to pull it, but space is limited in the gh and only the best of the best will get to stay in ground. I love the taste of mallika, but wouldn't mind putting another citrus flavored mango anyway. I had to prune a lychee and white sapote also because of this last fall. Luckily they rebounded pretty quickly and looks like I'm only sacrificing this year for no fruit for the lychee. Even then, I'm seeing a mixed blooms.The white sapote branches have been not so strong, so I've been trying to run the fan towards it. Even if I have to prune it again, it is a super fast growing tree and it wouldn't be set back at all.
