While we mostly enjoy the presence of trees in our garden, there are times when they can become a nuisance. Trees are just plants and any plant can become a weed, and knowing how to kill a tree is no different from killing a weed.

There are several ways how to kill trees; let’s take a looks at a few.

Killing a Tree by Girdling

Remove the bark completely around the circumference of the trees. This way how to kill a tree is called girdling. This is one of the most effective methods for killing trees as it will always work. The tree will be unable to transport nutrients from the leaves to the roots and will die in a matter of weeks.

How to Kill Trees by Paving Around Them

Knowing how to kill tree roots is the same as knowing how to kill a tree. Tree roots need to breathe and if they are suffocated, the tree will die. Paving over tree roots, even mulching too deeply over tree roots, will slowly suffocate the tree and will end up killing trees that have their roots covered.

How to Kill a Tree with Salt

In wars past, salting the earth was how traitors were punished. Land that has salt added to it will not support life, even tree life. Be aware that salting will end up killing trees, grass and any vegetative life in the immediate area. Also, it may be quite some time before anything else grows there.

Methods for Killing Trees with Herbicide

Herbicides can be very effective for dealing with zombie trees that have been cut down, but continue to grow back. On a hot dry day, cut back the tree as much as possible and paint the fresh cuts on the tree with a full strength herbicide. Also, try making fresh cuts on the tree or drilling into the tree trunk and inserting herbicide into the wound. Please note that it is your responsibility to follow all Federal, state and local laws and regulations regarding the use of herbicides.

How to Kill Trees by Cutting Them Down

Cutting down a tree is among the most effective methods for killing trees. Start with cutting the outer limbs and continue inward. Once the limbs have been safely removed, cut down the main trunk. Drill into the remaining truck several times. If you would like to complete how to kill tree roots, fill the holes with salt, herbicide or nitrogen. Once the tree stump is dead, it can be chopped out easily.

Trees, while sometimes lovely, are not always growing in the best place. Wondering how to kill tree weeds or what is the best methods for killing trees does not go against the norm. Learning how to kill trees safely and effectively can help keep your garden safe and beautiful.

Note: Chemical control should only be used as a last resort, as organic approaches are more environmentally friendly.

How to Kill a Tree

The Spruce / David Beaulieu

Trees lavish so many benefits on a property and its inhabitants that the very suggestion someone might wish to kill a tree is likely to elicit gasps of disbelief. In addition to their beauty, trees can function as living privacy fences and noise barriers. They can furnish shade both for you and for your shade garden. Trees not only provide a home to wildlife but also offer "cover" that will make wild birds feel safe enough to visit your bird feeder and spend enough time there for bird watchers to thoroughly admire their colorful plumage and delightful antics. It is hard for some gardeners to imagine why anyone would ever wish to kill a tree.


For medium-sized and larger trees with a diameter of more than 5 inches, the herbicide must reach directly into the plant’s vascular system to access the roots. Application consists of a series of cuts or injections downward into the bark, followed by direct application of the herbicide into the cuts or holes. The chemical is then transmitted throughout the tree, killing the tree and roots. Chemicals used in these herbicides include triclopyr, picloram, 2,4-D and dichlorprop.

Herbicides applied directly to the soil surface are carried down into the root system with rainfall or watering. The chemicals kill the roots when they come into direct contact with them. Chemicals that work in this way include bromacil, hexazinone and tebuthiuron.


Option 2: Rock Salt

Although it takes longer than chemical herbicide, rock salt can effectively kill tree roots by robbing them of water.

TOOLS AND MATERIALS Available on Amazon
– Rock salt
– Water
– Drill (with 1-inch or larger drill bit)

1. Drill several holes 3 to 4 inches deep into the cut surface of the tree trunk.

Before you stow your power tool, bore several additional holes into any larger roots that are exposed near the ground.

2. Fill the holes completely with rock salt, and pour water into them to fill to the top.

Avoid overfilling, as the rock salt solution is harmful to surrounding vegetation and toxic to pets—you won’t want any spillover. Repeat this process several times for a few months, and eventually rock salt will kill the tree roots. (You’ll know the roots are dead when there is no longer any regrowth from the trunk.)

Fear that the roots have invaded a sewer line or your foundation? Maybe you wish to keep the decomposing material from feeding unattractive fungus. In either case, you could also attempt digging the larger tree roots out of the ground. It’s an arduous process, but once you remove them you can reclaim your lawn.

How to Make a Homemade Root Killer for Drains

The effects that tree roots have on your sewer lines can lead to a devastating plumbing and landscaping bill. To prevent these significant issues, here are some homemade DIY root killer recipes and tips.

Pour Rock Salt Down the Toilet

Rock salt is a harsh chemical compound that is mainly used to melt ice and snow on sidewalks and roadways. It is also an effective herbicide and sewer root killer that destroys roots that have invaded your pipes and septic system. To use rock salt as a sewer root killer, pour a handful of the ingredient into your toilet bowl and flush.

Do this once every couple of weeks. Flushing some rock salt down into the sewer will kill any roots that have made their way inside, as well as preventing new roots from getting any closer. You can pick up some rock salt at any local home improvement or hardware store.

Homemade Foaming Sewer Root Killer

You can use a homemade foaming solution to kill tree roots that have found their way into your sewer system. Roots typically enter the drain line from above, so using anything that combines with water will merely pass through the entire pipe without contacting the roots.

To deal with the root problems you can add foaming action to a salt solution to kill roots effectively.

Foaming Root Killer for Drains Recipe

  • 1 cup regular table salt
  • 1 cup baking soda
  • 1 cup vinegar
  • 1 cup of boiling water

Mix all the ingredients, then immediately flush down the toilet. The baking soda and vinegar start to fizz when mixed.

This fizzing action allows the salt solution to fill the pipes so that it comes in contact with the roots and kills them on contact. However, it will take some time for the dead roots to get washed from the drain so you won’t see immediate results.

Powerful Sewer Root Killer – Copper Sulfate or Sodium Chloride

Place ½ pound of copper sulfate or sodium chloride into your toilet bowl and flush, so it entirely clears the bowl. Place another ½ pound into the toilet and flush again.

Do this four times, until you’ve flushed two pounds of copper sulfate or sodium chloride into the sewer where you’re having trouble with root growth. For the next 12 hours, be sure you don’t use the toilet or any water that will drain into the sewer.

This allows the chemicals to take effect. Make sure to repeat the process twice a year to keep the sewer lines open. You can pick up copper sulfate or sodium chloride at your local home improvement stores, like Home Depot and Lowes.

Use Epsom Salts to Kill Tree Stumps

Epsom salts are a common household item that is often used in footbaths but has plenty of other uses beyond the bathroom. You can use Epsom salts for plants to condition the soil in your garden, and in stronger doses can get rid of tree stumps and can act as an excellent weed killer.

If you have a felled tree stump in your yard, its roots could still be growing underground and searching for the water in your pipes and septic tank. Using an Epsom salts solution kills and rots the tree, including the roots that have found their way into your sewer lines.
