Will Roundup Kill Trees? +Controversial Issues that will Shock You

When large amounts of weeds have invaded our soil, we sometimes resort to using roundups to augment the jobs of a weeder. Roundups are undeniably effective in killing weeds but many users are asking “Will RoundUp kill trees?” You will know the answer plus lots of substantial information about this product by the end of this article.

Roundup Info

Roundup has gained popularity not because of its effectivity but because of the whispering campaigns about pesticides. As a gardener, I understand the saliency of these liquids. However, the masses are not fully aware of its benefits and that is why they presume that this is all evil.

This product kills weeds without farmers having to disturb the land. Learn the importance of decreased tilling in our Soil Building article. Next,​

Glyphosate is the key ingredient found in Roundup. It is a non-selective herbicide (herb killer). Since it does not work for specific kinds of weeds, it can get rid of clovers, dandelions, other weeds that have broad leaves and even grass.

Another characteristic that you have to bear in mind when you’re using Roundup is that it works systemically. Unlike other weed killers which only target the parts of the plant that gets in contact with the formulation, Roundup will be absorbed by the plant and it will take effect on the entire plant. This means it can damage the whole herb with just a few drops.

Will Roundup Kill Trees?​

The simple answer is yes. Roundup can kill trees.

It can affect its growth as the roots absorb the glyphosate. To be more specific, as this tree soak up the Roundup, certain nutrients (micro and macro) would not be absorbed as usual. Plant survival will be problematic, growth will be stunted and the plant will be predisposed to numerous diseases in the long run.

Getting Rid of Unwanted Trees

Despite the fact that many people are learning how to save a dying tree, there are others who deem the death of a tree necessary. And these people make use of Roundup to do it.

If you are planning to do so, the first step is to read the instructions at the back so as to get the correct ratio of your mixture. The computation is based on the size of the tree, the type of the tree and the concentration of the needed Roundup.

After this, you have to select one from the three ways of application:

  1. Bark of the tree
  2. Cutting downward wedges in the trunk
  3. Drilling holes in the trunk​

Prepare the materials accordingly, you will need an ax or chainsaw or drill. Make sure you wear your personal protective equipment to protect yourself from any potential danger.

These three methods actually expose the sensitive portions of the trees and create a receptacle in which you would be pouring down your mixture. Choose according to the available tools at hand, and depending on the condition of the tree. Let us say you can easily tear a bark of a tree, then it would not be necessary to drill holes anymore.

Saturate the trunk accordingly. Wait for few weeks and you will see obvious deterioration in your tree’s well-being.

Let me share these videos I have found on the web that I believe will be helpful for you:

Controversies Addressed

First Issue

One of the major concerns why people are avoiding the use of Roundup is that they believe that it can cause cancer. I do not think it would be that harmful to humans. We actually consume more chemicals that are substantially toxic than this (e.g. nicotine and caffeine). The effects of glyphosate are only evident in plants and not in animals.

Animals and humans have a different method for absorption. Hence, it does not pile up in our tissues and cells.

Second Issue

Another topic that must be addressed is environmental concerns. Most people think that Roundup will contaminate ground waters. The ingredient glyphosate has a very strong bond with soil. On top of that, before it can actually be pulled down by the virtue of gravity, the microbes have already consumed Roundup.

Third Issue

The banning of this product is being pushed, but, let me just inform you too that there are more than 500 researches that can prove the safety of Roundup. Certain regulatory boards such as the US Environmental Protection Agency, The American Soybean Association, National Corn Growers, and CropLife America vouch on the safety of this formulation. If it has been recognized by multiple offices to be safe then I believe it is.


RoundUp, though intentionally made for killing weeds are found to be effective in killing trees as well. It is evidently deadly in crops but it does not pose detrimental effects on the environment and humans.

You must have already been exposed to excessive glyphosate as your brain isn’t working right. It is toxic to humans.
