- Salt can kill vegetation and other plant life.
- Salt water can kill the tree by watering it with salt water. However, the water may also kill surrounding grass. It will remain in the ground for a while, stopping any new growth.
You can drill several holes around the tree’s base using a long drill bit. Make sure you are facing the downwards with your drill bit.
Make a mixture of two parts water and one part salt.
Then, pour the salt water into each hole.
Fill the gaps with mud. Within a few weeks the tree should be dead.
If you prefer, you can plug the holes with sand or mud. If you have any remaining issues with your soil, Gypsum can be used to help it heal.
Make sure the tree dies. You can’t reverse this process once you have poured in salt. When carrying salt water to the tree, make sure that salt water doesn’t get everywhere.
