13 best stump killers

Stump killers are products specifically designed to remove or kill tree stumps and their root systems. They are commonly used in gardening, lawn care, and landscaping to eliminate unwanted stumps that can be unsightly or obstructive. Here's what you need to know about stump killers:

  1. Purpose: The primary purpose of stump killers is to accelerate the decay and decomposition of tree stumps and their roots, ultimately causing them to rot and break down. This makes it easier to remove the stump or plant over it.

  2. Chemical Composition: Stump killers often contain active ingredients such as potassium nitrate (saltpeter) or glyphosate. These ingredients work by disrupting the growth and life processes of the stump, leading to its deterioration.

  3. Application: Stump killers are typically applied directly to the cut surface of the stump. This can be done by drilling holes into the stump and filling them with the product or by applying it as a liquid or granular solution to the exposed stump surface. The product is absorbed into the stump and transported to the roots, where it begins the process of decay.

  4. Timing: Stump killers are most effective when applied shortly after tree removal, ideally within a few weeks.Freshly cut stumps absorb the product more readily.

  5. Safety Precautions: When using stump killers, it's essential to follow safety guidelines provided by the product manufacturer. This may include wearing protective clothing and gloves, avoiding contact with the skin or eyes, and keeping the product away from children and pets.

  6. Decomposition Time: The time it takes for a stump killer to completely decompose a stump varies depending on factors like the type and size of the tree, the product used, and environmental conditions. It can take several months to several years for the stump to break down entirely.

  7. Physical Removal: While stump killers facilitate decomposition, they do not instantly remove the stump. Once the stump has rotted sufficiently, it can be easier to remove manually using tools like a stump grinder, axe, or shovel.

  8. Environmental Impact: Some stump killers may have environmental considerations, especially if they contain glyphosate. It's essential to choose products that align with your environmental and safety preferences.

  9. Alternative Removal Methods: In addition to stump killers, there are alternative methods for removing tree stumps, including mechanical grinding, burning, or hiring professional tree removal services.

  10. Local Regulations: Be aware of local regulations and restrictions regarding the use of stump killers or the removal of trees and stumps. Some areas may have specific rules in place.

In summary, stump killers are products designed to expedite the decay and decomposition of tree stumps and their root systems. They contain active ingredients that promote the breakdown of the stump, making it easier to remove or plant over. When using stump killers, follow safety guidelines and consider the environmental impact of the product you choose. Stump killers are one of several options available for dealing with unwanted tree stumps in your garden or landscape.

User questions & answers

Question: i have a dead ash tree stump.. it measures about 24 inches across ..will this product disolve the stump
Answer: What this product type does is softens the stump from the inside(the more holds you drill into any solid wood the better-and make sure to do some around the sides angling downward to meet a hole drilled through from the top). You can also use this on any large roots running off the stump which will aid in removal when your ready. These products will work better (faster) if not used on a freshly cut tree-being dried out for at least a year will speed up the process. Once the wood has been softened by a "stump killer" you can have it removed or, as I do, you can break up the stump (axe etc) to remove it.
Question: Can this be applied to sucker trees
Answer: It will kill (or severely damage) the tree if you do. Google "sucker stopper". There is a product made just for to stop suckers from growing without harming the plant. Good Luck.
Question: Will this kill grass? I have extensive poison ivy roots in a grassy area in a corner of my property
Answer: It will probably kill grass. I only use it for hard-to-kill weeds that may be woodsy, like a small Palo Verde or some large weeds that resemble grass with very long blades. If you want to kill poison ivy, cut it short to about 3 inches in length, wrap a paper towel around the stubs and drench it with the brush killer. Be careful not to spill it on the grass.
Question: What percentage of triclopyr is in it
Answer: The percentage of triclopyr in Fertilome Brush Killer and Stump Killer is 8.8%.

User questions & answers

Question: Cut down a big tree will this kill stump ,and how long would it take
Answer: Provided you paint the product on the stump immediately after cutting; not 10 minutes later, it's pretty much fool-proof. Because there is an applicator doesn't necessarily mean you must use it. I have a 4X4 in, by approx. 1/2 in deep white pyrex dish with a small handle that I pour a few oz of stump and vine herbicide into prior to making any plant cuts. I use a $0.99 (dollar store) one-inch wide paint brush to apply the poison completely over cuts as soon as the sawing has finished. The applicator goes back into the bottle to prevent spilling: It is never used since plant trash/dirt will quickly contaminate the herbicide bottle. Dispose of used paint brush as directed to prevent water contamination. Best I can tell, the death of the plants is pretty much in 1-7 days: They just never sprout again.
Question: We have roots growing thru our lawn next door - would this kill the tree next door by cutting the roots and applying? Hopefully
Answer: I am not sure but if you try, you need to have a fresh cut and apply the herbicide only to the part that you want to kill. Paint the cut thoroughly and may be apply it twice. It could kill the tree if you apply it to the part still connected to the tree. On the other hand, if you cut the roots cleanly, you may not need to use the herbicide for most trees.
Question: For those of you who used this to kill invasive vines, did it work? I need to eradicate this dreadful Oriental Bittersweet that has invaded my land
Answer: Did not work on trumpet vine .Would temporarily kill and then New growth appeared from dead looking stump. I have tried it for a over a year. Also didn’t work on Tree of Heaven.
Question: Do you just paint the cut of the vine, such as bind weed or grape vine, or do you need to paint the stem from the cut to the ground
Answer: You need to make a fresh cut, and then paint the vine (or weed tree, in my case) where you've cut it. An old cut won't work.

User questions & answers

Question: Is Tordon used straight out of the bottle, or does it need to be mixed (diluted) with water like a concentrate
Answer: Straight out of the bottle on freshly cut stump or sprout. Only need to apply product to outer rings of stump.
Question: does the tree have to be cut down first
Answer: This is the most powerful tree/scrub/vine killer I have found. A large gum tree was cut down and several trees grew back to medium size. I just took a couple of bottles out and poured it at the base of the trees and it took them out. It just soaks into the ground into the roots. I had a very large crepe myrtle that was essentially a tree. After we cut it down I put it on the stump and I doubt if it will ever come back. I think I have used too much. My yard had become overrun with vines. When I treated the crepe myrtle it killed 1 holly below it and harm the 2 hollies next to it. I was treating some vines in a holly hedge and it hit the hollies hard. They are still alive and I hope they come back. In a different area we we treating vines in a camellia hedge and it took out a few of them. My lesson learned is less is better if there are other plants around that you want to keep. Anyone know how long this stuff lasts before it breaks down?
Question: Would this work by drilling holes in the tree with out cutting it down
Answer: The Short answer is Yes/No. I have a hill on my property that is full of cottonwood, and no other chemical worked as good as this one. The cottonwood is extremely tough to kill, took a few tries to figure out the best way to use it. I drilled 3/8" holes around each tree at its root ball, drilled as deep as I can that button out the drill bit and fill the hole with this stuff, for large trees, it may take a few months to show signs of dying, just be patient, it will work. I hope this helps.
Question: How is this product applied
Answer: apply a circle where the bark meets the wood. That is where all the life in a trees trunk is. the vast majority of a trunk is hard wood and is used only for structure so to do more is a waste. I am a forester and have used gallons of tordon it is a very good product.

User questions & answers

Question: Will this kill out sumac and their rhizones? permanently
Answer: Kathleen, This is tough one to answer for sure. The label doesn't make such a claim. But in my personal experience, I have seen it work this way many times. So in some cases I have sprayed vines along my property border and a week later, vines in my neighbors yard some 5-10 feet away have died even though there was no clue they were linked or part of the same plant I treated. Now will it perform like this for every plant? One would think yes but I've not seen this happen across the board. I say that because in other cases, other vines I have sprayed along the border may have a few shoots 5-10 feet on my side but the very same treatment has not always killed them too. I know because I have used this treatment strategy a few times to see just how much I can affect. In summary, I would say it might be able to purge related rhizones but results could vary from plant to plant. Results are probably also be affected by how much you spray, how hot it is, etc. Cheers, Jonathan U-Spray Bugspray
Question: I want to kill vines, if this gets on the soil, will it also kill plants that have roots in the area
Answer: In my experience, this only works when it comes in contact with live plant tissue (leaves or woody).
Question: Will this kill blackberry vines
Answer: Don't know for sure...but probably.
Question: Will this kill a fig tree
Answer: I doubt. I used it To kill small Pecan trees. I did spray three times (some of trees are a foot and some of them are maybe 2 feet high ) It made leaves turn to brown but didn't kill trees .had to dig them out

Question: Wil this product kill poison ivy

Question: does this stuff ever expire to where it no longer can be used
Answer: Interesting question. I used the product 3 years ago, new in the container according to directions. I still have all 5 stumps, although slightly less solid than they were 3 years ago.
Question: So how does is the stump out granules applied and does it kill new growth like the stump out liquid supposedly does
Answer: dont' know anything about the stump out liquid. I heard about it on a garden radio show . they recommended for new growth of poison ivy. I purchased for a nandina tree because I am tired of digging up and cutting off new shoots all the time. I put it around the tree/bush and so far has worked to kill off new shoots but not original tree. no new growth for about 1 month since i put it down

User questions & answers

Question: I have a 6" diameter oak tree growing in a bottle brush plant. Will it harm the bush too
Answer: I suspect it would. Painting the fresh cut with a strong glyohosate may be a better plan.
Question: Michigan delivery problems? Where can i order or buy this in Michigan
Answer: There should be no problem with delivery to Michigan. Tordon RTU is registered for use in your state..
Question: Can you plant new trees or bushes near the dead stump
Answer: Hi, good question, I believe you can because you only apply Tordon to a freshly cut stump. You don’t apply it to the exterior of the tree or bark ( I believe). There are a couple of good videos on YouTube on how to safely apply this product. For example, be sure you wear a good pair of gloves.
Question: I have volunteer trees growing in my azaleas. Will my azaleas be safe if I am careful to only apply to the weed trees
Answer: If your good tree’s roots are touching the volunteer roots of the tree you’re trying to kill, you may lose the good tree. I lost a $1500 Japanese Maple.

User questions & answers

Question: How is this solution mixed and how much of a coverage area can I expect from this bottle? Thank you for your help
Answer: My husband used it and this is his response. "One bottle goes a long way since it is diluted directly 1:8 in a pump sprayer. It took 2 sprays to kill unwanted growth from a Live Oak, probably due to the amount of rain we get almost everyday. You could probably use a garden hose with a sprayer attachment but I don't feel you have as much control. We were able to direct the spray on the unwanted growth and save my other plants nearby."
Question: Has anyone tried this on english ivy
Answer: It may, it depends on how established and rampant the problem is. I bought a home with it a few years years worth of growth on it and tried the Bayer with no success. I had to use this: Triclopyr 4E Herbicide 1 Gallon - Replaces Remedy Ultra. It is expensive, but it killed it off where I sprayed two applications (over the course of a month). Ivy is very resilient, so unless you kill all of it, it will slowly creep back in. If you want to try the bayer first because it is inexpensive, I would use it just about undiluted and use a agent like bonide to ensure it sticks.
Question: Wondering what the mix ratio (ounces per gallon) is required by the concentrate
Answer: Add 4 fl. oz.(1/2 cup, 8tbsp) to 1 gallon of water to spray on brush. Brush undiluted to kill Kudzu, Poison Ivy, Poison Oak, Blackberries, and also stumps and root sprouts leaves.
Question: what's the percentage of triclopyr
Answer: It depends! Amazon is selling multiple concentrations of this product all grouped together, and their product descriptions do not make this clear. The "Concentrate" seems to have 8.8% triclopyr, but the "ready to use" gallon and 1.3 gallon sizes are diluted 10 times from that amount...my 1 gallon bottle says 0.8% triclopyr, 99.2% other ingredients. Be careful which one you choose! I thought I was getting the 8.8% and so am sending it back.

    It may be necessary to first drill a small pilot hole in the stump to prevent the nail from bending.

    User questions & answers

    Question: What percent triclopyr is in bioadvanced 704655a triclopyr kills kudzu, poison ivy and other tough brush killer plus non-selective weed grass control
    Answer: used a couple years ago - worked very well. now, seems formula has changed as product is not very effective. will not kill kudzu now. extremely disappointed in current product and feel as if I wasted my money. would not recommend
    Question: We have killed everything topside, but we have roots coming in to the basement, will this work if directly applied to those roots
    Answer: Go on Amazon and purchase "Bonide Stump and Vine Killer". It has an applicator to apply the product directly on freshly cut roots. Killed all my roots dead, right to the bottom. Hope this helps.
    Question: Has anyone used this product on Chinaberry trees (Melia azedarach var. umbraculifera)? Was it effective
    Answer: We don't have Chinaberry Trees in East Tn. yet. I bought this to kill Poke Weed. Tried it on other weeds, it worked but took over 3 weeks! Not happy with the product, I can make a homemade weed killer better. 1gal. white vinager, 1cup Epson salts and 2T Dawn. Works quicker, I would not buy this product again. I am stuck with 2 gallons of this. DO NOT LIKE! Haven't tried it on Poke Weed,butifit took so longt kill a Standard weed, don't count on it to kill something bigger.
    Question: Is this Bayer Advanced Brush Killer safe with grass
    Answer: It says it will temporarily yellow grass and that seems to be true when I used it. Grass hasn't died yet. This is not a total vegetation killer like Roundup, but for broadleaf weeds, vines and trees.
