Q.mango tree
how much area does a mango tree root needs
as i have rocks after 6 feet of good soil and also have 10 feet of sides with good soil will it grow good
Mango trees produce long taproots, which search for water and anchors this massive tree in the ground. The best soil is at least 19 1/2 feet deep, but with good watering practices, mangos grow well in 3-foot-deep soil. Check the area for impermeable layers under the topsoil, which will stop the roots from growing downward. It is important to transplant the mango tree while young, since the roots quickly grow deep.
The soil must drain well for the mango tree to survive.
Mango trees like moderately fertile soil but have a low tolerance for salty soil.
