Pine trees are usually desirable landscape trees in your yard. Towering high into the sky, they provide ample shade as well as a home to a variety of animals. Sometimes, however, it may be necessary to kill a pine tree. It may be interfering with a power line or it might be diseased. For whatever reason you have to kill pine trees, rest assured it is an easy process to accomplish. Non-selective herbicide works best at killing a pine tree, but it must be applied correctly to work.
Identify which pine tree you want to kill and mark it by tying a ribbon around it. This will prevent you from inadvertently killing the wrong tree.
Take a hatchet or axe and make horizontal but non-overlapping cuts around the entire trunk of the pine tree. Extend the cuts into the sapwood, which is the lighter colored wood of the trunk. The cuts should be 2 inches long and 1 to 3 inches apart.
Use a spray bottle and spray 1 to 2ml of non-selective herbicide into each cut. A good non-selective herbicide to use is Roundup.
Repeat the application after seven days if the tree isn't completely dead.
Things You Will Need
- Hatchet or axe
- Non-selective herbicide
- Spray bottle
- Consider purchasing a hypo-hatchet. This is a hatchet that injects herbicide into the tree every time you strike the tree. These come in handy when multiple trees need to be killed.
- Keep the herbicide off desirable plants. The herbicide will kill all plants it comes in contact with. If you accidentally get some on a desirable plant, wash it off completely before the herbicide has a chance to dry.
