VPG is a popular gardening products company. Under its Fertilome line, it markets the Brush Stump Killer which is a highly effective herbicide. With 8.8% triclopyr as its active ingredient, it causes stumps to wither away quickly (effects start within one to six weeks) after application.

The liquid formula is easy to apply. On a newly-cut stump, simply paint this formula on with a brush. However, if the stump is a few months old, drilling holes into the top and sides of the stump and pouring liquid down them is the method that guarantees the most success.

Coming to the usability of the product, it works just as well on several kinds of unwanted woody plants and vines as it does on tree stumps. While its application on stumps is direct-from-bottle, to use it on vines and small shrubs, it should be diluted as per instructions. This makes it a versatile option. What’s more, the product comes in a generous pack size of 32 ounces. That amount of liquid is enough to be used on multiple stumps and will last for a good while.

So, if you have numerous stumps that need to be removed and you do not have a significant budget for doing so, you can buy this Brush Stump Killer by VPG Fertilome. Safe to say, it is the best tree stump killer for people who want the most value for their money.

Check Latest Price on Amazon

The Tordon RTU is a remarkably effective herbicidal offering from Dow AgroSciences. It is designed to be a highly functional product and has many simple yet nifty features that makes it stand out among competitors.

When applying herbicides to stumps, you might often find it hard to keep track of the areas you have tended to. Tordon RTU has a convenient solution to this problem. The liquid is in a striking blue shade which acts as a marker dye and makes it easy to spot already covered parts of the stump.

In terms of efficiency, the Tordon RTU is second to none. Once applied with a paintbrush or a spray pump, it seeps into the root system of the stump with ease and poisons it. This leads to rotting and, eventually, the death of the stump. Furthermore, it can be used with the same efficiency to kill around 20 species of plants, making it a truly versatile product.

For added convenience, the liquid is free-flowing, meaning that it comes out of the bottle without resistance. Also, it has a no-freeze formula. This helps you to store it for long periods and use it even in the coldest weather conditions. Moreover, for a freshly-cut stump or vine, the liquid can be used straight out of the bottle without needing to mix it or dilute it with water.

To sum up, the product is well thought out and is a suitable option when it comes to buying the best tree stump killer.

Copper Sulfate Small Crystals
Check Latest Price on Amazon

Copper sulfate is a commonly used herbicide that is freely obtainable in the market at economical rates. Earthworks Health’s 10-pound bag is one such product, available in the form of crystals of copper sulfate.

Unlike liquid tree stump killers, powdered or crystallized copper sulfate is not suitable for external application. This is due to its high toxicity that can damage neighboring plants and also seep into the underground water supply. Instead, the crystals are dissolved in water to form a solution which is then poured into holes drilled on the tree stump.

Additionally, if you face the problem of leaking sewer lines due to the encroachment of tree roots into them, these crystals can come in handy. Pour 1 pound of the crystals directly into the sewer line and sit back to find the roots shriveled and gone. Repeat this process once every 6 months to keep your underground piping completely free of tree roots.

Earthworks’ copper sulfate crystals are 99 percent pure, so they work as expected every single time. Further, they ship in factory sealed bags to guarantee freshness and quality. All in all, you can buy this bag of crystals for effective and quick removal of pesky tree stumps as well as troublesome roots that enter underground plumbing.

What We Liked

  • 10-pound bag is enough to last for a long time
  • Starts working within a day or two
  • Crystals are easy to dissolve and apply
  • Economical alternative to chemical herbicides
  • Can be used to clear sewer piping of invasive roots
  • Choice between large, medium, and small crystal sizes

What We Didn’t Like

  • Not suitable for external application on large tree stumps
  • Bag doesn’t carry detailed instructions for use

Most chemical tree stump killers are toxic and deadly to any plants or grasses they come in contact with. For this reason, if you apply any such chemical to a tree stump surrounded by vegetation, plants you do not intend to damage will also be negatively impacted. Thus, it is imperative to use safer alternatives in such scenarios.

Amount of Solution Required

Small stumps or one or two large stumps can be dealt with using less quantity of a chemical solution. However, for several large stumps or multiple usage cycles, you might want an economical option that does not necessitate frequent buying.

Safety Measures

Tree stump killers are potent chemicals that can be harmful to human beings as well if used carelessly. To avoid this, it is advisable to cover all exposed areas of the skin with suitable clothing while handling the chemicals. Additionally, do not forget to wear goggles, face masks, and protective gloves.

Conclusion
