The Best Stump Killer Options


Trees can add a majestic feel to any landscape. However, some trees can prove to be a nuisance by sprouting roots beneath power lines and driveways. If this happens, the tree can be cut down, but the stump and roots will remain—locked firmly in the ground. Manually digging or chopping out left-behind tree, brush, and woody vine stumps is challenging at best, and in some cases, nearly impossible without heavy equipment. Depending on the species, if the tree or vine was alive when cut down, new aggressive shoots may soon appear around the stump—restarting the cycle.

The solution? Chemical stump killer. Stump killer is an herbicide that’s specially designed to kill a stump and its roots. Stump killers eliminate the need to chop or dig up stubborn stumps and prevent new shoots from forming. Read on for tips on how to choose the best stump killer for your yard.

What to Consider When Choosing the Best Stump Killer

Stump killer isn’t a quick-fix solution for getting rid of stumps. The degradation process can take from a few months to a year. Eventually, the stump will decompose, and the hole left behind can be filled in and smoothed over.

Stump Size and Location

The size of the stump is a significant factor in deciding whether to manually or chemically remove it. Stumps that sit a couple of inches above ground level can pose a tripping hazard. If the stump is in a part of the yard that sees frequent foot traffic, it might be better to have it manually removed for safety purposes.

Chemical stump removal products help kill any size stump that would be challenging to remove manually. Smaller stumps, less than a couple of inches in diameter, may be worth digging out to get rid of them sooner.

Working Time

The actual time it takes a chemical stump remover to decompose a stump can vary, depending on the tree or plant species and whether the stump is green and freshly cut.

In the case of newly cut stumps, a stump removal herbicide that travels to the roots is necessary to stop resprouting. Depending on the product, results may appear within 6 to 8 weeks. The stump itself, however, may not decompose for another few months.

Another type of stump that’s a good candidate for chemical removal is a dead or “seasoned” stump. Although these stumps are incapable of sending up new shoots, they can be hazardous or in the way of new landscaping plans. In this case, the stump removal product will contain a chemical that hastens the degradation of the old wood, which can take a few months or longer.

After a few months, the owner may be able to pour kerosene on a partially decomposed seasoned stump and burn it. Some chemical stump remover products are designed to be used in conjunction with stump burning. Before going this route, check with local fire codes to see if burning the stump is permissible in your community.


Chemical stump killers contain potent herbicides and other chemical components that hasten stump decomposition. Most stump-removal products contain one or more of the following active ingredients:

  • Glyphosate: Glyphosate is a broad-spectrum herbicide that travels within the stump’s vascular system to kill the roots. It’s useful in killing green stumps.
  • Triclopyr: Triclopyr is a systemic herbicide that tricks the living roots of a stump into rapid growth that overwhelms the tree and kills it. Triclopyr is found in products that kill green stumps.
  • Potassium nitrate: Also called “saltpeter,” potassium nitrate not only kills the stump, but it’s also one of the best ingredients for helping it decompose quickly. It’s found in products for both killing green stumps or for decaying seasoned stumps.
  • Picloram: Picloram is a systemic herbicide that destroys woody-type plants. This herbicide is found in products designed to both kill and decompose the stump.
  • Sodium metabisulfite: Sodium metabisulfite is an inorganic chemical that helps decay seasoned tree stumps. It’s not meant for use on green stumps that may regrow.


The chemicals in stump killers are often toxic and can irritate skin and eyes or trigger respiratory symptoms if the fumes are inhaled. The manufacturer will usually suggest wearing chemical-resistant gloves and goggles. For ultimate protection, consider wearing a respiratory mask and protective clothing, including long pants and a long-sleeve shirt. Keep children and pets away when treating the stump, and cover the treated stump with a tarp or board during the decomposition process.

Some types of stump remover, especially those containing potassium nitrate, are flammable, so don’t use them near an open flame or smoke during application.

Application Process

Various chemical stump killers may come with slightly different instructions, but the following application method is standard.

  1. Using a chainsaw, cut the stump low to the ground and remove side bark to reveal as much surface area as possible.
  2. Drill holes in the surface of the stump (more than a few inches in diameter). Alternately, use a chainsaw to cut grooves on the stump’s surface.
  3. Apply the chemical stump killer or decomposing agent. Depending on the product, this might mean sprinkling granules in the holes and then pouring hot water over the stump. It might also mean painting a liquid on the surface of the stump or spraying it. Spraying is usually reserved for stumps with green sprouts, and the sprouts are sprayed as well.
  4. Cover the stump to keep kids and animals safe.
  5. Check on the stump every 3 to 4 months. Eventually, it will become spongy and can be dug out or burned and then dug out.

Our Top Picks

To qualify as one of the top picks, the stump-killing product should effectively destroy the roots of a living tree or vine and prevent it from regrowing. If the product is designed to remove seasoned stumps, it should hasten the decay of the stump so that the owner can easily remove the remains with a shovel. The following stump-killing/removal chemicals may differ in type, but each offers a reliable way to eliminate an unwanted stump.

Best Overall

The Best Stump Killer Option: Dow AgroSciences RTU548 Tordon RTU Herbicide

A favorite of farmers and landscapers, Tordon RTU, manufactured by Dow AgroSciences, comes in as the Best Overall pick in this lineup. It dependably kills green stumps all the way down to the roots, and it contains picloram, which speeds the degradation process. Tordon comes in a deep blue liquid that stains the top of the stump, so users who are removing multiple stumps will know which ones have already been treated.

It comes ready to use with an included screw-on squirt top (think dishwashing liquid) for applying directly to the stump without the need to spray or add water to the product. It treats most nuisance trees, including hawthorn, elm, and alder, but should not be used on stumps with roots that might be intertwined with desirable tree roots to prevent damage to the desirable tree. It comes in a 1-quart bottle.


The Best Stump Killer Option: VPG Fertilome 32295 Brush Stump Killer

Triclopyr is the active chemical ingredient in Fertilome’s Brush and Stump Killer that’s designed to kill tree roots to stop invasive shoots from growing. It’s also useful for speeding the decomposition of the stump. Fertilome is well suited to killing small stumps, up to about 6 inches in diameter, and woody brush and vining stumps, such as those associated with wisteria.

The concentrated chemical comes in a 32-ounce bottle and should be diluted at the rate of 8 to 16 tablespoons per gallon of water. Use the highest concentration for hardest-to-kill stumps, such as poison ivy. Once mixed with water, the solution is painted on the stump with a paintbrush.

Best Bang for the Buck

The Best Stump Killer Option: Bonide (BND272) Ready to Use Stump-Out Stump Remover

This stump remover will speed the degradation of seasoned stumps, and it comes at an affordable price point. It contains sodium metabisulfite and is best suited to use on tree stumps where the tree was cut down at least 12 months prior. It’s well suited to use on trees that do not send up sprouts or regrow after being cut down, such as aspens, pines, and cedars.

Drill holes in the stump, fill them with Stump-Out granules, and then pour hot water over the stump to start the decaying process. The stump can degrade by itself, which could take a few months, or removal can be hastened by pouring kerosene on the stump 6 weeks after treatment with Stump-Out and burning the stump. (Check local fire codes before going this route.) The product comes in a 1-pound container.

Best with Sprayer

The Best Stump Killer Option: BioAdvanced 704645A Brush Killer and Stump Remover

For no mix or mess, check out BioAdvanced Brush Killer and Stump Remover that comes in a ready-to-use spray bottle. The product is best suited for small stumps that are commonly associated with woody bushes and vines, including kudzu and poison oak. BioAdvanced is an all-purpose herbicide that also kills noxious and invasive species.

Spray the product, which contains the active ingredient triclopyr, until all exposed surfaces on the stump are thoroughly wet but not dripping. Also saturate any new shoots that may be growing from the stump. BioAdvanced is formulated to penetrate deep into the stump and work its way down to the roots and will kill and hasten decomposition.

Honorable Mention

The Best Stump Killer Option: Spectracide HG-66420 Stump Remover

Containing potassium nitrate for speeding stump degradation, Spectracide Stump Remover is designed to work only on seasoned stumps where the stump is already dead and is not sending up shoots. The product comes in granular form, and users should either drill holes in the stump or cut grooves into the top of the stump with a chainsaw before applying.

Stump Remover is then used to fill the holes or grooves, and then hot water is poured over the stump to activate the decomposition process. As with other stump decomposition products, once the stump is soft, it can be doused with kerosene and burned, if desired. Stump Remover comes in a 1-pound container.
