I have a young dwarf mango tree that is approx. 2 years old. I made the mistake of leaving it attached to the stake it came with until quite recently. The tree is flourishing and doing really well with plenty of new growth, however the trunk is just bending right over, probably because it was staked for too long and didn’t develop a strong enough trunk. I want to cut the newer branches off to ease some of the weight but I’m worried about putting the tree into shock or something. How do I fix this problem!?
