Diesel fuel is a controversial topic when it comes to tree care and landscaping. While some people suggest using diesel fuel to kill tree stumps, others warn against it due to safety concerns and the ineffectiveness compared to other methods. This has led to discussions on alternative methods and the exploration of various techniques to remove unwanted tree stumps. The exploration of these methods highlights the ongoing search for efficient and safe ways to address tree stump removal, balancing effectiveness, cost, and potential environmental impacts.

What You'll Learn
Diesel fuel can be used as a chemical tree stump killer
Another way to use diesel fuel as a tree stump killer is by drilling holes in the stump and filling them with the fuel. This method, however, may not be as effective as the diesel fuel needs to be absorbed by the tree's fibres, which can take a long time. Additionally, the heat generated by the drill bit can cause the diesel fuel to boil, creating pressure that can break the bit or damage your drill.
It is important to note that using diesel fuel as a tree stump killer can be messy, time-consuming, and expensive. There are alternative methods that may be more effective and safer, such as using Epsom salt or a triclopyr chemical stump killer. Epsom salt, when mixed with water, creates a poison that causes the stump to decay. Drilling holes in the stump and filling them with Epsom salt can eliminate the problem in less than a year, with results showing in as early as two to three months. Rock salt can also be used in a similar manner, although it may be more harmful to nearby plants.

Large quantities of diesel fuel are required to kill trees
While diesel fuel can be used to kill trees, it is important to note that large quantities are required for it to be effective. This method is often suggested by landscaping workers and has been discussed in various online forums. However, it is not the most efficient or cost-effective way to remove stumps.
Using diesel fuel as a chemical stump killer requires a significant amount of fuel to be poured directly onto the stump. Even then, it may need to be mixed with another chemical to increase its effectiveness. This can be dangerous and is not recommended for home use. Additionally, the cost of diesel fuel can be high, and the process can be time-consuming.
There are alternative methods that can be more effective and safer. For example, Epsom salt, which contains sulfur and magnesium, can be mixed with water to create a poison that causes the stump to decay. This method can show results in as little as two to three months. Rock salt is another option, but it can be harmful to nearby plants, so it should be used with caution.
Another approach is to cut the tree at the base and immediately spray it with a mixture of diesel and other chemicals, such as Remedy or Roundup. This method, used for mesquite trees, involves leaving about 12 inches of the trunk and then removing the dead stump with a tractor the following year. However, this process still requires a large quantity of diesel and can be expensive due to the cost of the additional chemicals.
In summary, while diesel fuel can be used to kill trees, it is not the most recommended method due to the large quantities required, safety concerns, and potential costs. Alternative methods, such as using Epsom salt or cutting the tree at the base, may be more effective and safer options.

Mixing diesel fuel with other chemicals can be dangerous
Mixing even a small amount of gasoline with diesel is a bad idea, as it will depress the flashpoint of the diesel, which can be dangerous given that pockets of higher concentrations of gasoline can develop in a tank. As little as 1% gasoline contamination will lower the diesel flashpoint by 18 degrees Celsius, causing premature ignition in the diesel engine and leading to engine damage. Gasoline contamination can also damage the fuel pump and diesel injectors due to a drop in lubrication. Mixing gasoline with diesel will result in incomplete combustion, producing large amounts of black smoke and reducing power and performance. If you continue to use the fuel, you risk damaging the vehicle's computer sensors through overheating or soot accumulation.
Additionally, the octane rating of the fuel mixture will be affected. A 2% diesel contamination in gasoline will lower the overall octane rating by 1 point, and a 10% contamination will lower it by 5 points, creating problems in most engines. The heavier diesel fuel can sink to the bottom of the gas tank, resulting in the injection of both gas and diesel into the intake manifold or cylinder. This can lead to partially burned diesel fuel, leaving deposits on pistons, valves, and spark plugs, causing serious damage to the vehicle.
Other chemicals, such as DEF (Diesel Exhaust Fluid), can also be mixed with diesel fuel to intentionally ruin an engine. When DEF is exposed to engine heat, it crystallizes and clogs the fuel filter, leading to engine failure. Sodium silicate, also known as water glass or liquid glass, is another substance that can be mixed with diesel fuel. When heated, sodium silicate turns into glass, causing permanent damage to the engine.

Alternative methods to kill trees include using Epsom salt
While diesel fuel is one way to kill trees, it is not the only way. Alternative methods to kill trees include using Epsom salt. Epsom salt is a natural and budget-friendly way to remove a tree stump. It is a good option for those looking for a DIY method that is safe and not physically demanding.
The process of using Epsom salt to kill a tree stump is simple and involves drilling holes into the stump and filling them with Epsom salt. Specifically, you should use a 1-inch drill bit to drill multiple holes that are at least 8 inches deep, leaving a few inches between each hole. You then pour Epsom salt directly into the holes, filling them to the top. Afterwards, slowly add enough water to moisten the salt. Depending on the season, you may need to cover the stump with a tarp to prevent rainwater from diluting the Epsom salt. This process should be repeated every three weeks until the stump is dead.
The benefit of using Epsom salt is that it dries out the root system and prevents it from absorbing the moisture and nutrients it needs to survive. Epsom salt is also less harmful to the surrounding soil compared to other chemical solutions, making it a good option for those who want to plant in the same place after the stump is removed.
It is important to note that while Epsom salt is a safe and effective way to kill tree stumps, it may take an extended amount of time compared to other methods. Additionally, Epsom salt should only be used to kill unwanted trees, as using it on healthy trees is unnecessary and harmful to the environment.

Cutting trees at the base and spraying diesel is another method
However, it is important to note that this method can be expensive, as Remedy costs around $100 per gallon, and you would need to mix one quart of Remedy with three quarts of diesel. Additionally, this method may not work well if it is raining, as the diesel mixture needs to stick to the tree.
Before attempting to use diesel as a tree killer, consider other methods that may be more effective, safer, and less expensive. For example, using Epsom salt or a triclopyr chemical stump killer can be more effective and safer alternatives.
If you decide to use diesel, it is important to take the necessary precautions and follow the manufacturer's instructions for any additional chemicals used, such as Remedy.
