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.
There’s a reason why plants are called complex interconnected organisms. If you put salt on the soil where that tree is growing, it also might reach to other plants in the area and kill them as well.
