Kensington Pride mangoes in particular tend to have strong apical dominance. Young trees will grow to over 1 metre before they start to push out branches. To develop a strong trunk the trees should be allowed to grow to over 1 metre in height initially. They are then cut back to a height of between .6 to .7 of a metre. The site of first cut is important for the development of a strong frame.
Mangoes grow in flushes, each flush is delineated by a concentrated whorl of leaves on the stem.
These would need to be thinned out to 3 or 4 if a good tree structure is to be attained. Even so this would be a weak point, prone to breaking during storms or strong winds. It will ensure that the branches are well spaced out up the trunk and only 3 shoots will normally develop, resulting in a strong frame for future development. After the initial cut allow the three shoots to grow into branches of over 1 metre long. These are then cut back to about a metre in length, this will give you a good strong branch for supporting the growing tree.
