I live in Dubai. There is a tree called Damas, which we where advised to remove from our garden. The roots are spreading very wide, up to 6-7 meters, in the surface of the garden, absorbing all the water of the soil. We already have cut the trees, the trunks and the roots, which are not less than limbs of the tree and are very hard to remove.
I read the in your site about drilling and using salt, herbicide or nitrogen. My question is, does killing the tree make removing of the roots and trunk easier? I want to plant new trees instead. What if I just leave the trunks in places that we don't want to grow something.
How close to a dead trunk I can plant a new tree? Does that salt or the herbicide harm the trees and plants that we plant in the garden later, and for how long? And, what if we do not remove the roots?
Do they get to be a part of the soil after we killed the tree or do we have to remove them all and replace the soil?
