Homemade Stump Killer Methods (Pro Tips for Long-Lasting Wood Control)

Stumps are more than just unsightly remnants of felled trees; they’re potential hazards, breeding grounds for pests, and obstacles to future landscaping projects. While professional stump grinding is an option, it can be expensive. Luckily, there are several effective homemade stump killer methods that can save you money and provide long-lasting control. In this article, I’ll walk you through various methods, their costs, and the science behind their effectiveness, drawing on my own experiences and industry best practices.

Understanding the Stubbornness of Stumps

Before we get into the methods, let’s understand why stumps are so resilient. A freshly cut stump is still very much alive, drawing nutrients from its root system. This makes it capable of sprouting new growth, which is the last thing you want. The key to successful stump killing is to disrupt this nutrient flow and accelerate the decomposition process.

The Saltpeter (Potassium Nitrate) Method: A Slow but Sure Solution

The saltpeter method is a time-tested way to kill stumps, relying on potassium nitrate to accelerate decomposition. Here’s how it works:

1. Drilling the Stump: Using a drill with a large bit (at least 1/2 inch), drill several deep holes into the top of the stump, as well as around the sides. The more holes, the better. Aim for holes that are 8-12 inches deep.
2. Applying Saltpeter: Fill the holes with potassium nitrate (saltpeter). You can find this at garden supply stores or online.
3. Adding Water: Pour water into the holes to dissolve the saltpeter and help it penetrate the wood.
4. Sealing the Stump: Cover the stump with a tarp or plastic sheet to keep rain out and maintain a moist environment. This helps the saltpeter work more effectively.
5. Patience is Key: This method takes time, typically several months to a year, depending on the size and type of wood.

Cost Breakdown:

• Potassium Nitrate: A 5-pound bag typically costs between \$20 and \$40. The amount you need will depend on the size of the stump. For a stump with a 1-foot diameter, you might need 1-2 pounds.
• Drill Bit: If you don’t already have a suitable drill bit, expect to spend \$10-\$30.
• Tarp/Plastic Sheet: A basic tarp can be purchased for \$5-\$15.
• Water: Negligible cost.

Total Estimated Cost: \$35 – \$85

My Experience: I used the saltpeter method on a particularly stubborn oak stump in my backyard. It took almost a year for the stump to become soft enough to break apart, but the results were worth it. The best part was that it required minimal effort after the initial application.

Data Point: According to a study by the University of Minnesota Extension, saltpeter is an effective method for accelerating wood decomposition, particularly in hardwood species like oak and maple. They found that stumps treated with saltpeter decomposed 30-40% faster than untreated stumps.

The Epsom Salt (Magnesium Sulfate) Method: A Natural Alternative

Epsom salt is another natural option for killing stumps. It works by drawing moisture out of the wood, creating a hostile environment for the tree.

1. Drilling the Stump: Similar to the saltpeter method, drill several deep holes into the stump.
2. Applying Epsom Salt: Fill the holes with Epsom salt crystals.
3. Adding Water: Add water to dissolve the Epsom salt.
4. Repeat as Needed: Over time, the Epsom salt will be absorbed into the wood. You may need to repeat the application every few weeks, especially during dry periods.

Cost Breakdown:

• Epsom Salt: A large bag of Epsom salt (8 pounds) typically costs between \$10 and \$20.
• Drill Bit: (If needed) \$10-\$30.
• Water: Negligible cost.

Total Estimated Cost: \$20 – \$50

My Insight: I’ve found that the Epsom salt method works best on smaller, softwood stumps. It’s a gentle approach, but it can still be effective with patience and persistence.

Data Point: A study published in the Journal of Arboriculture found that high concentrations of magnesium sulfate can inhibit the growth of tree roots, making it a viable option for stump control.

The Rock Salt (Sodium Chloride) Method: A Simple and Inexpensive Option

Rock salt, or sodium chloride, is a readily available and inexpensive option for killing stumps. It works similarly to Epsom salt, drawing moisture out of the wood.

1. Drilling the Stump: Drill several deep holes into the stump.
2. Applying Rock Salt: Fill the holes with rock salt.
3. Adding Water: Add water to dissolve the rock salt.
4. Covering the Stump: Cover the stump with a tarp to prevent rain from diluting the salt.

Cost Breakdown:

• Rock Salt: A 40-pound bag of rock salt typically costs between \$10 and \$20.
• Drill Bit: (If needed) \$10-\$30.
• Tarp: \$5-\$15.
• Water: Negligible cost.

Total Estimated Cost: \$25 – \$65

Personal Story: I once used rock salt to kill a small pine stump in a remote corner of my property. It was a simple and affordable solution, and it did the job effectively over several months.

Data Point: While not specifically studied for stump killing, sodium chloride is known to be toxic to plants in high concentrations. This makes it an effective, albeit potentially environmentally impactful, option for stump control. Be mindful of runoff and potential harm to surrounding vegetation.

The Bleach Method: A Controversial but Effective Approach

The bleach method involves using household bleach (sodium hypochlorite) to kill the stump. This method is controversial due to environmental concerns, but it can be effective if used carefully.

1. Drilling the Stump: Drill several deep holes into the stump.
2. Applying Bleach: Carefully pour undiluted bleach into the holes.
3. Sealing the Stump: Cover the stump with a tarp to prevent the bleach from leaching into the surrounding soil.

Cost Breakdown:

• Bleach: A gallon of household bleach typically costs between \$3 and \$5.
• Drill Bit: (If needed) \$10-\$30.
• Tarp: \$5-\$15.

Total Estimated Cost: \$18 – \$50

Caution: Bleach can be harmful to the environment and should be used with caution. Avoid spilling bleach on the surrounding soil, and consider using a less harmful method if you are concerned about environmental impact.

Expert Opinion: According to the EPA, sodium hypochlorite can be harmful to aquatic life and soil organisms. It should be used sparingly and with careful consideration of potential environmental consequences.

My Perspective: I’ve used the bleach method in the past, but I now prefer more environmentally friendly options. The potential risks to soil health and water quality outweigh the benefits of its relatively quick action.

The “Wait and Rot” Method: A Hands-Off Approach

The “wait and rot” method is the simplest and most hands-off approach to stump removal. It involves simply waiting for the stump to decompose naturally.

1. Patience is Key: This method requires patience, as it can take several years for the stump to decompose completely.
2. Encourage Decomposition: To speed up the process, you can keep the stump moist and covered with organic matter, such as leaves or wood chips.
3. Optional: Fertilizer: Applying a nitrogen-rich fertilizer to the stump can also help accelerate decomposition.

Cost Breakdown:

• Time: The primary cost is the time it takes for the stump to decompose.
• Organic Matter: (Optional) Free if you have access to leaves or wood chips.
• Fertilizer: (Optional) A bag of nitrogen-rich fertilizer typically costs between \$10 and \$20.

Total Estimated Cost: \$0 – \$20

My Story: I had a large maple stump in my backyard that I decided to leave to decompose naturally. It took about five years for the stump to completely disappear, but it eventually became a haven for insects and fungi, enriching the soil in the process.

Data Point: A study by the University of Wisconsin Extension found that natural decomposition rates for tree stumps vary widely depending on the species of tree, the climate, and the presence of decomposer organisms.

The Mushroom Inoculation Method: A Biological Approach

This method involves inoculating the stump with mushroom spores to encourage fungal decomposition. Certain types of mushrooms, such as oyster mushrooms or shiitake mushrooms, are particularly effective at breaking down wood.

1. Drilling the Stump: Drill several holes into the stump.
2. Inoculating with Spores: Insert mushroom spawn or spore plugs into the holes.
3. Keeping it Moist: Keep the stump moist by watering it regularly.
4. Harvesting Mushrooms: As the mushrooms grow, you can harvest them for consumption.

Cost Breakdown:

• Mushroom Spawn/Spore Plugs: A bag of mushroom spawn or a set of spore plugs typically costs between \$20 and \$40.
• Drill Bit: (If needed) \$10-\$30.
• Water: Negligible cost.

Total Estimated Cost: \$30 – \$70

Fun Fact: Not only does this method kill the stump, but it also provides you with a source of delicious and nutritious mushrooms!

Expert Tip: Choose mushroom species that are well-suited to the type of wood in your stump. Oyster mushrooms, for example, are particularly effective at breaking down hardwoods like oak and maple.

Data Point: According to the USDA Forest Service, certain types of fungi can accelerate wood decomposition by as much as 50%.

The Herbicide Method: A Chemical Solution (Use with Extreme Caution)

While this article focuses on homemade solutions, it’s important to acknowledge the herbicide method. This involves using chemical herbicides, such as glyphosate or triclopyr, to kill the stump.

Important Note: Herbicides can be harmful to the environment and should be used with extreme caution. Always follow the manufacturer’s instructions carefully, and wear appropriate protective gear.

1. Cutting the Stump: Cut the stump as close to the ground as possible.
2. Applying Herbicide: Apply the herbicide directly to the freshly cut surface of the stump.
3. Repeat as Needed: You may need to repeat the application several times to ensure the stump is completely killed.

Cost Breakdown:

• Herbicide: A bottle of glyphosate or triclopyr typically costs between \$20 and \$40.
• Protective Gear: Gloves, safety glasses, etc. \$10-\$20.
• Applicator: (Optional) A sprayer or brush can be used to apply the herbicide. \$5-\$15.

Total Estimated Cost: \$35 – \$75

Environmental Considerations: Herbicides can have significant environmental impacts, including harming non-target plants and animals, contaminating soil and water, and contributing to herbicide resistance. Consider the environmental consequences before using herbicides, and explore alternative methods whenever possible.

Regulatory Information: The use of herbicides is regulated in many areas. Check with your local authorities to ensure that you are using herbicides legally and responsibly.

My Recommendation: I strongly advise against using herbicides unless absolutely necessary. There are many effective homemade stump killer methods that are less harmful to the environment.
