Neighbor has a tree that shits leaves and gunk all over our back patio and the roots are coming under our fence and fucking up our concrete. I want to start spraying the limbs hanging over our fence with salt water and pour buckets of the stuff down on the roots if necessary. Approx how much salt am I going to need and how long do I need to keep dousing it to see this tree dead? Tree is approx. 20 foot tall and 10 years old.
In which case, why not just spray herbicide on the limb? You’d need a constant supply of gallons of saltwater over several days to really stop it
