Burning out a tree stump is a common method of removal. It involves drilling holes into the stump, filling them with fuel, and lighting the stump on fire. While some people use gasoline or kerosene, others explore the use of diesel fuel. However, it is important to exercise caution when burning stumps to avoid unintended consequences, such as fires spreading to nearby areas or releasing carbon into the atmosphere. Stump grinding or letting insects decompose the wood are alternative methods to consider.

Drilling holes in the stump
When drilling holes, it is recommended to aim for a depth of around 4 to 10 inches, depending on the stump's size. Spacing the holes about one to four inches apart is ideal. Drilling at a 45-degree angle can also make the stump removal process easier. After drilling, remove any debris from the holes.
Once the holes are prepared, they can be filled with various substances to aid in stump removal. One option is to use stump-rotting agents, such as potassium nitrate or Epsom salt, which cause the stump to decay and become spongy over several weeks. Alternatively, for a quicker burn, you can fill the holes with diesel fuel, kerosene, or vegetable oil, and let it soak for around 48 hours before igniting. This method is more immediate but carries a higher risk of fire, so caution and close monitoring are necessary.
After igniting the stump, it's important to keep the fire active and controlled until the stump is completely reduced to ash. Afterward, use a shovel to extract any remaining roots and break down large fragments. Fill the resulting hollow spot with fresh soil, and you've successfully reclaimed the space once occupied by the stubborn stump!

Filling the holes with diesel fuel
To fill the holes with diesel fuel, first, use a drill to create holes in the stump. The number of holes depends on the size of the stump, with larger stumps requiring more holes. The holes should be deep, with some sources recommending a depth of 4 inches. If possible, drill both vertical and horizontal holes to improve airflow.
Once the holes are drilled, fill them with diesel fuel. You may need to fill the holes multiple times, as the stump will absorb the diesel. Be cautious, as diesel fuel is highly flammable, and the fumes can be dangerous. It is essential to take appropriate safety precautions, such as ensuring adequate ventilation and avoiding open flames or sparks.
After filling the holes with diesel fuel, you can light the stump on fire. Some sources recommend adding additional fuel, such as wood or charcoal, to help the fire burn more effectively. It is important to monitor the fire and ensure that it does not spread to unintended areas. Keep the area around the fire wet to prevent accidental fires.
The stump will likely burn for a couple of days, and the coals will continue to smolder even after the fire appears to be out. Therefore, it is crucial to thoroughly soak the area with water after the fire seems to be out. This process may need to be repeated several times to ensure that the stump is entirely burned away.

Lighting the stump on fire
Prepare the Stump
Drill multiple deep holes in the stump using a large drill bit. These holes should be at least 4 inches deep and spread out across the top and sides of the stump. The holes will allow the diesel fuel to penetrate the stump and aid in combustion. If possible, create a tic-tac-toe or similar pattern with the holes to maximize surface area.
Soak the Stump with Diesel Fuel
Pour diesel fuel into the drilled holes, allowing the stump to absorb the fuel. You may need to add fuel multiple times, as the stump will absorb it. You can also try using kerosene or a commercial stump remover in addition to diesel fuel to enhance combustion.
Prepare the Surroundings
Clear the area around the stump to minimize the risk of accidental fires. Keep the surrounding area wet to prevent the fire from spreading unintentionally. Ensure that you have a water source or extinguisher nearby in case of emergencies.
Light the Stump
Before lighting the stump, add a bit more diesel fuel to the holes. Use a long stick or torch to light the stump from a safe distance, being cautious of any fumes that may have built up. Do not use a lighter or attempt to light the fire with your hand near the stump.
Monitor the Fire
Keep a close eye on the fire as it burns. You may need to add more fuel or wood to keep it going. Use a shovel to break up any charred wood and expose fresh material to the flames. Be aware that the stump may shift or split as it burns, so maintain a safe distance.
Extinguish the Fire
Once the stump has burned down completely, thoroughly douse the remaining embers with water to ensure they are extinguished. Stir the ashes to check for any remaining hot spots. It is crucial to monitor the fire and its aftermath to prevent unintended consequences.

Keeping the area around the stump wet
Firstly, before igniting the stump, it is essential to clear the surrounding area of any debris and flammable materials, including leaves, branches, birdhouses, and other combustible items. This creates a safety perimeter to prevent the fire from spreading unintentionally.
Next, set up a reliable water source, such as a hose connected to a water supply, near the stump. This is a crucial precaution in case of emergency. Should the fire spread or get out of control, you can immediately douse the surrounding area with water to contain the blaze.
Additionally, always keep a fire extinguisher or fire suppression tools nearby. These tools will enable you to swiftly address any unintended fires that may occur during the burning process. It is also advisable to have a shovel at hand to extract any remaining roots or break down sizable stump fragments after the fire has burned out.
When preparing to burn the stump, it is imperative to wear protective clothing, including fire protection gloves, eyewear, and a face mask. These safety measures will shield you from any flying embers or smoke inhalation hazards.
Finally, never leave a burning stump unattended. Ensure that at least one responsible adult actively monitors the fire's progress from start to finish. This vigilant supervision ensures that any potential issues are promptly addressed, and it enables the swift extinguishing of the fire in case of an emergency.
By diligently following these safety guidelines, you can effectively keep the area around the stump wet and minimize the risks associated with burning tree stumps.

Using an alternative method to burning
Burning tree stumps is a very effective way to remove them, but it can be dangerous and is illegal in many places. The smoke from burning stumps can be a health hazard, and the process is not good for the environment as it releases harmful chemicals into the atmosphere.
If you are looking for an alternative method to burning, here are some options:
- Digging out the stump manually: This involves using a shovel or pickaxe to dig around the stump and expose the roots. You can then loosen the roots and pull the stump out of the ground.
- Using a roto-tiller: A roto-tiller can be used to break up the stump by pulverizing it. You can then remove the pieces with a shovel or rake.
- Using a stump grinder: A stump grinder is a machine that can be used to grind up the stump, leaving you with a supply of mulch.
- Letting insects eat the stump: One commenter on a forum noted that they had better luck letting bugs and ants eat the stump than trying to burn it. They noted that it takes a long time for the stump to rot, but it is a safer option.
- Using a 55-gallon drum: This method involves placing a 55-gallon metal drum around the stump if it is small enough. The drum is then filled with dry cedar wood or charcoal, which is lit on fire to burn the stump.
- Drilling holes and using chemicals: This method involves drilling holes in the stump and filling them with chemicals like potassium nitrate, rock salt, or diesel fuel to help the stump burn. However, this method still involves burning the stump, which may not be suitable for your needs.
These alternative methods may be more labour-intensive or time-consuming than burning, but they can be safer and more environmentally friendly options.
