Tree stumps can be an eyesore in any landscape, and they can take a painfully long time to decompose on their own. Fortunately, there are a variety of methods available for removing tree stumps quickly and effectively. 

In this article, we will explore the various options for killing and removing tree stumps from your yard. We’ll also discuss the advantages and disadvantages of each method so that you can make informed decisions when it comes to tackling the task. Read on to learn how to kill a tree stump efficiently and safely!

Why People Remove Stumps 

People may want to get rid of tree stumps for a variety of reasons. Here are a few of the most common reasons to remove tree stumps. 

Unsightly Appearance – It is no secret that tree stumps can often detract from the overall aesthetic of a landscape, making it look unorganized and messy.

Safety Risk – Depending on where the stump is located, it can pose a tripping hazard for people walking around. This can be especially dangerous if the stump is located near stairs, near where children play or in other areas with heavy foot traffic.

Pests & Disease – Tree stumps can become overgrown with weeds and grass or attract insects and other pests. They can also spread diseases to nearby plants, making them a health risk in your garden or yard.

Ways To Naturally Kill A Tree Stump

Killing a tree stump can be done using several different methods; here are 5 ways to tackle a stubborn stump naturally. 

1. Epsom Salt 

Who would’ve thought the bath salts you use for soaking could double as a tree killer? Although Epsom salt is made up of sulfur and magnesium, which are normally good minerals for plants and trees, in high concentrations, it can successfully kill them. 

Here are the steps to kill a tree stump with Epsom salt. 

1. Obtain Epsom salt: Purchase a sufficient amount of Epsom salt from a local store or online. You’ll need enough to fill the holes you’ll drill into the stump.
2. Cut the stump: Trim the stump as close to the ground as possible. This will minimize the amount of living tissue and make it easier for the stump to die and decay.
3. Drill holes: Use a drill with a large diameter bit (about 1 inch) to create holes in the stump. Drill the holes 3-4 inches apart and approximately 8-12 inches deep, angling them slightly downward to facilitate salt absorption.
4. Fill the holes: Pour your Epsom salt into each hole, filling them all the way to the top. The salt will help to dry out the stump and inhibit its ability to absorb nutrients, eventually killing it.
5. Add water: Add just enough water to each hole to moisten the Epsom salt. This will help the salt dissolve and penetrate deeper into the stump.
6. Cover stump: Place a plastic tarp or sheet over the stump to protect it from rain and help retain moisture. This will also create a barrier that prevents the stump from receiving sunlight, which can help speed up the decay process.
7. Monitor progress: Check the stump periodically to see if it’s showing signs of decay. You may need to repeat the Epsom salt application process if the stump is not decomposing as expected. Keep in mind that this method can take several months to be effective.
8. Remove the stump: Once the stump is dead and decayed, you can remove it by breaking it apart with an axe, shovel, or other tools. The stump may become soft and spongy, making it easier to break apart. Depending on the extent of decay, you may also be able to use a pry bar or a pickaxe to help with the removal process.
9. Clean up: Clear away any debris and remnants of the stump. Dispose of them in a safe and responsible manner, following local regulations.
10. Fill the hole: Fill the hole where the stump was located with soil or topsoil to create a level surface. You may want to add grass seed, plants, or mulch to help blend the area with the rest of your yard. This will also prevent any tripping hazards and create a more visually appealing landscape.

It normally takes about 6-12 months for the Epsom salt method to kill the tree stump versus up to seven years for it to decompose naturally. Within the first two to three months, the stump will begin to decay, and then it will fully decompose after about a year. This is a longer process than other methods, but it is easy and cost-effective if you are not in a rush! 

2. Burning

Burning is another natural way to get rid of a tree stump. Yes, you just burn until there’s nothing left but ash. Burning is relatively fast compared to some of the other options and can easily draw neighbors’ attention, so you may want to give them a heads up if you plan to go this route.

Here are the steps for burning a tree stump:

1. Check local regulations: Before starting, ensure that burning tree stumps is allowed in your area. Some locations may have restrictions or require permits for open fires. 
2. Clear the area: Remove any flammable materials or debris surrounding the stump to minimize the risk of fire spreading.
3. Drill holes: Drill a series of holes into the stump, approximately 8-12 inches deep and 3-4 inches apart. These holes will help the fire penetrate the stump and burn it more effectively.
4. Add fuel: Pour very small amounts of kerosene into the holes. Allow the fuel to soak into the stump for several minutes. Be very careful when handling flammable liquids, and never use gasoline, as it can cause dangerous flash fires.
5. Build a fire: Place charcoal briquettes or firewood around and on top of the stump. Make sure the firewood or charcoal is in contact with the stump and the fuel-soaked holes.
6. Light the fire: Ignite the fire using a long match or lighter. Keep a safe distance and observe the fire as it burns.
7. Monitor the fire: Continuously monitor the fire to ensure it remains controlled and doesn’t spread. Keep a fire extinguisher, water hose, or bucket of sand nearby in case of emergency.
8. Let it burn: Allow the fire to burn down the stump until only ashes and charred wood remain. This process may take several hours, depending on the size of the stump.
9. Extinguish: Once the stump has been sufficiently burned, use a shovel to spread out the remaining embers and ashes, ensuring that the fire is no longer active. If necessary, douse the area with water to fully extinguish any remaining hot spots. Be cautious when handling the ashes, as they may still be hot.
10. Clean up: When the area has cooled, remove the ashes and debris from the burned stump. You may need to use a shovel or other tools to break apart any remaining charred wood. Dispose of the ashes and debris in a safe and responsible manner, following local regulations.
11. Fill the hole: Fill the hole where the stump was located with soil to create a level surface. You can also add grass seed, plants, or mulch to help blend the area with the rest of your yard.

Remember that burning a tree stump can be a risky method, so always prioritize safety and follow local regulations. 

3. Rock Salt 

Using rock salt (sodium chloride) to kill a tree stump is another inexpensive and simple solution, although it can take longer compared to other methods. 

Here are the steps to kill a tree stump with rock salt:

1. Buy rock salt: Purchase a sufficient amount of rock salt from a local store or online. You’ll need enough to fill the holes you’ll drill into the stump.
2. Drill holes: Use a drill with a large diameter bit (about 1 inch) to create holes in the stump. Drill the holes 3-4 inches apart and approximately 8-12 inches deep, angling them slightly downward to facilitate salt absorption.
3. Fill the holes: Pour rock salt into each hole, filling them to the top. The salt will help to dry out the stump and inhibit its ability to absorb nutrients, eventually killing it.
4. Add water: Add just enough water to each hole to moisten the rock salt. This will help the salt dissolve and penetrate deeper into the stump.
5. Cover the stump: Place a plastic tarp or sheet over the stump to protect it from rain and help retain moisture. This will also create a barrier that prevents the stump from receiving sunlight, which can help speed up the decay process.
6. Monitor progress: Check the stump periodically to see if it’s showing signs of decay. You may need to apply water regularly and repeat the rock salt application process if the stump is not decomposing as expected. Keep in mind that this method can take several months to be effective.
7. Remove the stump: Once the stump is dead and decayed, you can remove it by breaking it apart with an axe, shovel, or other tools.

Note that while rock salt is effective in killing tree stumps, it can also kill other plants nearby, and you run the risk of contaminating the soil. Epsom salt is the more eco-friendly alternative if you’re looking for the more environmentally friendly salt option. 

4. Total Darkness 

Using a tarp, large bag, or something else to cover the stump to deprive it of sunlight will create an environment that promotes decay. This method is eco-friendly, but it could take a very long time to be effective. 

Here are the steps to kill a tree stump using a tarp or darkness:

1. Cut the stump: Trim the stump as close to the ground as possible. This will reduce the amount of living tissue and make it easier for the stump to die and decay.
2. Drill holes: Drill several holes into the stump, about 8-12 inches deep and 3-4 inches apart. This will help increase air circulation and encourage the decay process.
3. Apply nitrogen source: Fill the holes with a high-nitrogen fertilizer, compost, or manure to promote the growth of decomposing microorganisms. These microorganisms will help break down the stump over time.
4. Wet the stump: Moisten the stump and the surrounding area with water. This will help create a suitable environment for decay.
5. Cover the stump: Place a large, heavy-duty tarp or plastic sheet over the stump. Ensure the tarp completely covers the stump and extends a few feet beyond its edges. This will block sunlight and trap moisture, which helps to speed up decay.
6. Secure the tarp: Use bricks, rocks, or other heavy objects to weigh down the edges of the tarp, preventing it from blowing away and ensuring that sunlight does not penetrate the covered area.
7. Monitor progress: Check the stump periodically for signs of decay. It may take several months or even years for the stump to decay completely. Keep the stump moist and reapply the nitrogen source if necessary.
8. Remove the stump: Once the stump is decayed and soft, you can remove it by breaking it apart with an axe, shovel, or other tools. Fill the hole with soil or topsoil to create a level surface, and blend the area with the rest of your yard.

5. Natural Decomposition 

Lastly, you can always allow nature to take its course and let natural decomposition occur over time. While this option generally takes much longer than some of the others listed here, it’s quite simple and doesn’t require any special tools or products. All you need to do is wait! Depending on the size of your tree stump, it takes around three to seven years for it to decompose naturally. 

Other Stump Removal Options 

Here are a few other stump removal options if you do not want to try a natural method. 

6. Cutting or Grubbing Out

This method involves partially or completely cutting and removing the visible portion of the stump from the ground. A sharp spade can be used to cut down into the soil around the stump, allowing for easy removal with a shovel.

This method is labor-intensive and most effective for small to medium-sized stumps. Here’s the process for cutting or grubbing out a stump:

1. Gather tools: Obtain necessary tools, such as a shovel, mattock, axe, bow saw, pruning saw, loppers, and work gloves.
2. Clear the area: Remove any rocks, debris, or obstacles from around the stump.
3. Cut the stump: Trim the stump as close to the ground as possible to minimize the digging and cutting required.
4. Dig around the stump: Use a shovel and mattock to dig around the stump, exposing major roots. Start by digging a trench circling the stump, gradually working your way closer to the base. The trench should be deep enough to reveal the main roots extending from the stump.
5. Cut the exposed roots: Use an axe, bow saw, or pruning saw to cut the exposed roots. For smaller roots, loppers can be effective. Take care not to damage your tools by striking rocks or hard soil.
6. Remove soil and rocks: As you cut the roots, remove soil and rocks to gain better access to the remaining roots.
7. Pry the stump: Once most of the major roots are cut, use the mattock or a pry bar to pry the stump loose from the ground. Be prepared to cut any remaining roots that are holding the stump in place.
8. Remove the stump: With the stump loosened, lift and remove it from the hole. You may need assistance if the stump is large or heavy.
9. Clean up: Clear away any debris and remnants of the stump and roots. Dispose of them in a safe and responsible manner, following local regulations.
10. Fill the hole: Fill the hole where the stump was located with soil or topsoil to create a level surface. You may want to add grass seed, plants, or mulch to help blend the area with the rest of your yard.

Keep in mind that cutting or grubbing out a stump can be physically demanding and time-consuming, especially for larger stumps or those with extensive root systems. 

7. Grind It Down 

Grinding a tree stump is a quick and efficient method for stump removal. You will need to rent, purchase, or hire a professional to use a stump grinder. Once you have a stump grinder secured, here’s how to grind down a tree stump:

1. Prepare the area: Clear any rocks, debris, or obstacles from around the stump. Trim the stump as close to the ground as possible (this will cut down on the total grinding needed).
2. Rent a stump grinder: If you don’t own a stump grinder, rent one from a local equipment rental store. Choose a grinder suitable for the size of the stump you need to remove. Make sure to get proper instructions on how to use the machine safely.
