Q.mangos falling off tree
Why are the mangos falling off my tree too soon? It’s growing nicely.

How old is your Mango Tree? Mango Trees do not began to bear fruit until they are 3 to 5 years of age.
If your tree does not get the right amount of water, it will drop fruit.
If the temperatures are not warm enough the plant will abort fruit.
Lack of pollination can also be an issue.
A tree will naturally drop fruit to thin the load on the tree.
