Killing tree roots

Question

I have to remove a diseased mesquite tree and large oleander. If I use an herbicide to kill the roots, how long do I have to wait to plant something else in the area?

Answer 1

The herbicides that you would use would likely be out of the soil within 24 to 78 hours.
Removing the roots from the ground would be important to insure a good healthy planting area may be more time consuming.
