How To Kill A Pine Tree: 5 Effective Ways
11 4 3
Pine trees are quite resilient and killing them by cutting them down does not always work unless you have a way to kill the roots. Even when you cut down the tree, its roots might still continue growing and a tree shoot might sprout from the trunk.
You may want to kill pine trees for several reasons. Large trees can cause serious damage to your foundation and driveway. The roots can damage pipes while the tree can block sun from reaching your yard. The lack of sunlight can destroy your lawn while the pine needles can leave your yard quite untidy.
When it comes to killing a pine tree, you can use one of several methods, which range from using simple natural chemicals to using chemicals. Here is a look at some of the ways to kill a pine tree starting from the slowest/least effective to the quickest/most effective.
1. Using Copper Nails
- High quality 1.5 inch long copper slating nails with many uses
- Great for roofing, DIY / home building projects, decor, boat building and more
- Pre-drill with a 3/32" or 7/64" bit before hammering for best results (prevents bending of the copper nail)
- Package includes 10 ounces (approx. 100 count) solid copper nails (Made in the USA)
If you perform a quick search on the Internet for how to kill pine trees you will find many websites that recommend driving several copper nails into a tree to poison it. While this approach technically does poison the tree, it is quite slow and not effective on most large and healthy trees.
If you compare using copper nails to the other methods of killing pine trees, this approach is quite slow and inconsistent. The copper nail approach is only recommended if you are unable to use any of the other approaches discussed here, but it is still probably a waste of time regardless.

Salt can be used to kill pine trees. If you want to use salt to kill a pine tree, you will have to drill holes into the ground so that you are able to access its roots. You will then need to prepare a concentrated solution of salt and pour it into the holes you have made.
Salt kills most plant life including trees but it is a somewhat slow method for killing trees. It is also important to note that salt can prevent plants from ever growing drill where it is poured far into the future, which makes it less than ideal for killing pine trees.

If you would like to use a messy approach to killing pine trees, you should consider burning it. Burning is most applicable if you live in a rural area. However, you should never do it during the dry season on a windy day to avoid getting it out of control. It is also important to have a fire extinguisher close by. Burning is not the best approach since it can be dangerous and not always effective.

4. Using Chemicals
One of the most popular and effective ways to kill pine trees is using herbicides that contain Glyphosate. However, it is important to note that the chemicals do stay in the soil when you apply it to the roots and you may be unable to grow anything else in that area for a while.
To kill a pine tree using this approach, you will need to drill several holes into its trunk and around the base, into its roots. Ensure that you drill the holes as deep as possible and at a downwards angle. It is also important to ensure that they are large enough to pour the herbicide. Fill the holes you have made with the herbicide and wait.
Protect yourself when applying the chemicals by wearing appropriate clothing. You should also avoid doing it when it is windy since you risk getting the chemicals onto yourself or the surrounding plants that you don’t want to kill.
5. Tree Girdling
Girdling your pine tree is the most effective way to kill it. Girdling a pine tree prevents nutrients from moving from its roots to the top. Tree girdling is a quick and effective approach to killing pine trees and has the least environmental impact.
Tree girdling involves cutting a deep ring around the tree and making sure that both ends connect. A better approach would be double girdling, which involves cutting 2 separate rings close to each other and removing the bark between the rings.
Tree girdling is a quick and easy way to kill trees and requires nothing besides a chainsaw or regular saw and a few minutes of your time. It is important to ensure that your rings are deep and connect. If the rings don’t connect, the tree will still manage to transport nutrients up the trunk.
The Bottom Line
Once you are sure the pine is dead, you can proceed to cut it down and use one of these methods to get rid of the tree stump. Or you can follow a few ingenious ideas and turn the stump into outdoor furniture.
You may choose to kill a pine tree for several different reasons and can use several different approaches. The 5 approaches discussed here are some of the most common and most effective. If you would like to kill a pine tree, it is up to you to decide which approach will be most effective.
