How to kill a tree

When you kill the trunk of a tree, it doesn’t mean that trouble is over. These options will go to help you a lot in many ways.

  • The tree roots system extends up-to 20 feet deep in the ideal soil and spread through a greater area.
  • The growth of plant roots can continue after the trunk history, and if it is close to the base of your property can cause unlimited damage.
  • You should remove the underground issues either by the use of chemicals or by natural methods.
  • Larger trees can be killed by the use of salts and chemicals too.

Tree stump removal chemical

The use of chemical herbicide is the fastest and effective way to kill tree trunks.

Tools and materials:

  • Saw.
  • Watering can or a gardening hose.
  • Glyphosate herbicide with 41 % or higher active ingredient concentration
  • Small bucket.
  • Garden Sprayer or paintbrush 


  • Make a fresh cut hit on the stump with the help of a saw, even if it was cut down a few days ago.
  • The slice will help to create a flat surface and expose the new flesh.
  • If the tree has three inches of diameter, the cut should be on the trunk’s whole surface.
  • Expose the new flesh on the outer surface of about two to three inches for larger trees.
  • Make the tree’s cambium layer ready for saturation.
  • Locate the outer ring under the bark with 2 to 3 inches of water.
  • The liquid will help carry herbicide from the live tissues to the tree roots in woody plants if its outer layer is still alive and growing.
  • Make a glyphosate herbicide solution with water and apply it to the tree trunk exposed cambium layer.
  • Use the handheld sprayer, paintbrush, or garden sprayer to do the task.
  • It would be helpful if you are careful while avoiding harming plants and grass around the trunk.
  • You can use a saw watering can or garden hose to spray 41% of glyphosate herbicide which is the active ingredient concentration kept in a small bucket. 
  • The tree roots will die in two weeks approximately.
  • The estimated time when the chemical can kill the original amount of trees above the trees is 2 to 3 months.

Use of rock salt

You can use salt to kill tree roots, but it is a time-consuming process rather than opting for an effective chemical herbicide. 

The thing you need:

  • Rock salt.
  • Water.
  • Drill with the 1-inch large drill bit.


  • Drill the holes 3 inches with depth in the cut surface of the tree trunk.
  • Now bore the additional holes in the more extensive roots that are near to the ground.
  • Pour rock salt into the holes to fill them and pour water into the top surface too.
  • It should not be overflowed, as the salt is harmful to the surrounding plants and pets.
  • Repeat this process, and finally, the salt will kill the tree roots completely.

Kill a tree with bleach

• To use bleach to kill a tree, cut the stumps with a hatchet below the point where the living branches emerge. This will reveal the live stump.

• The bleach is then poured into the stump after drilling holes in the external part.

• Additionally, you may create your own tree killer by putting white vinegar in a squeeze bottle.

  • Spray the tree roots’ solution; this will destroy the leafy top growth and kill the remaining tree roots.
  • Killing a tree with Epsom salt is another good alternative by drilling holes around the stump.
  • Pour the Epsom salt into each hole, and pour some water in these holes to moisten the salt.
  • But do not saturate salt thoroughly; it should be only moist.

Using a basal bark treatment

  • The basal bark applications involve spraying of labeled herbicide solution using a low-volume spray wand.
  • This method is best for woody plants.
  • Use the Gallon 4 ultra-ready to use the Triclopyr’s oil-based formula in basal bark application to kill the trees.

Killing trees with potent herbicides:

Herbicides contain an active ingredient, whether diluted or in undiluted form, and the additional components that can enhance their efficiency. Active ingredients include Triclopyr, triclopyr ester, and triclopyr amine.

Triclopyr herbicide

  • The homeowners use Triclopyr herbicide in diluted form, 0.8 % to 8.8 % products in the small containers of 802- 1.3 gal.
  • The amount of active ingredient present in herbicide chemical differs and is given on the herbicide tag as pounds of active ingredient per gallon of product or percentage terms.
  • The Triclopyr can kill up-to less than 50 % of the applied concentration within 60 days if used for land, and the rate of which is discreetly persistent.

Triclopyr Amine

  • It is a growth regulator-type herbicide that can cause abnormal and suppressed plant growth and results in plant death.
  • It can work best for a wide range of woody plants.
  • The commercial applicators that use triclopyr herbicide products contain 31.8 % of Triclopyr and are sold in2.5 gallon containers.
  • For certain types of applications like landscapes, commercial product suggests using these up-to full strength, whether diluted or undiluted, with the percentage of 8.8%.
  • The triclopyr chemical should not link with the non-target foliage or the roots of other plants.

Triclopyr Ester

  • Triclopyr Ester is also a growth regulator type herbicide like Triclopyr amine, useful for woody plants.
  • The herbicides that contain triclopyr ester and used by commercial applicators have 43.6% or 9.81% acid triclopyr sold in 2.5 gals or even larger containers.
  • You can buy these chemicals from agricultural supply stores and pesticide distributors.
  • If you want to make the basal bark applications, the full product can be diluted in water or oil for foliar applications.
  • The most common ready-to-use formula is in a diluted form that contains 9.81% of the product and is the undiluted form you want to use for basal bark applications and stump cutting treatments.
  • Plants can absorb the Triclopyr Easter as it is a highly volatile chemical and can cause unwanted damage.
  • The vaporization potential depends on the temperature; as if the temperature is above 80 degrees F, the vaporization will also increase up to 90 degrees F
