Buying Guide For The Best Stump Killer

The tree stumps are hard to remove due to the strong root connectivity of the tree. Various cutting and grinding equipment can be used to remove the stumps. For areas where heavy machinery cannot be used, the stump killers deal with these unwanted stumps. We have already gone through the list of the best stump killers available in the market. To further understand these stump killers, this buying guide will walk you through a few governing factors.

1. Reaction Time

While selecting a stump killer, its reaction time must be considered. Spraying the stump killer is only the first step in dealing with stumps. The next step involves the start of a reaction between the stump killer and the stump structure. Each stump killer has a different reaction time which takes weeks or months to set in.

The small size weeds or stumps usually react faster to the chemical solution, compared to larger size stumps. The rotting process starts within 4 weeks on average. The complete decomposition of the stump will then be dependent on its overall size. The breakdown of the inner structure also helps in weakening the stump which can be easily removed by small machines.

2. Stump Killer Type And Application Method

The stump killers are available in two types: the powder form and the liquid form. Each type of stump killer offers different properties compared to the other one. For the liquid stump killers, the spraying process is the most effective one. The liquid stump killers can be sprayed over the stumps at various angles.

The spraying process offers maximum penetration to the stump’s body. The liquid stump killers can also be poured over the stump area, but it doesn’t offer controlled coverage. For the powdered or granular stump killers, the method of application is different. Various holes are drilled in the stump body to establish contact between the powdered stump killer and the inner core of the stump. The power is then absorbed into the streams of the tree where it starts a reaction. Powders offer a controlled area of attack.

3. Active Ingredient

A stump killer consists of different chemical agents that offer a dominant role in the reaction. Due to their major portions, these ingredients are called active ingredients. Potassium Nitrate is one of the most commonly used active ingredients. Being a Nitrogen-rich compound, it accelerates the overall decomposition process. It is usually found in a powdered form. Magnesium Sulfate is a multi-functional ingredient. It enriches the soil with nutrients along with an accelerated decomposition process.

Being a form of salt, overuse of this ingredient can reverse the nutrient-enrichment process, causing harm to the plantation. Glyphosate is one of the popular weed killers. It possesses properties that are suitable for killing any type of plantation. Triclopyr is a synthetic ingredient developed by keeping certain characteristics of plants in mind. It mimics certain growth hormones of the plantation to stop its overall growth.

4. Overall Volume And Concentration

You would not want to spray or pour the stump killer as it is, over the stump. The liquid stump killers usually come in a highly-concentrated mixture. Adding external agents like water helps in decreasing the concentration of the stump killer solution. Every stump killer has a defined limit for mixing water. The pack of stump killers usually has the ratio written over the labels which explains how much stump killer can be added to a certain volume of water. The overall volume of the bottle helps in deciding how long the stump killer will last. Factors like the size of the stump also decide the portion of stump killer to be used.

5. Environmental Considerations

Even if the stump killers are used to destroy the tree stumps, they should pose a threat to the environment. The chemicals used in the stump killers can be harmful to the environment if overused. The nutrients of the surrounding plantation might be affected by uncontrolled spraying of the stump killer. Some of the liquid solutions penetrate the underground water source. Toxic ingredients can pollute water resources, making them unfit for use. The spayed plantation must be removed as soon as the decomposition is completed. Some chemicals also pose damage to the animals when ingested.

6. Miscellaneous Factors

The stump killer must resist certain environmental attacks to keep the reaction effective. It should not wash away in the heavy streams of rain. The solution should not react with the sunlight which might cause alteration in the core properties. Apart from this, proper safety measures are also important since stump killers contain harmful chemicals. Wearing safety gloves and eye protection helps avoid direct touch with the chemicals. If powdered stump killer is being used, wearing respirators keeps minute particles away from entering the lungs. Adequate clothing also offers protection to the full body while spraying the chemical solution.
