Tree stump killer buyer’s guide

The goal here is to permanently kill off the tree stump hanging around in your backyard. However, there is no instant stump killer to do that job so it is best that you must know some factors that you should consider before deciding to buy one.

Budget: You are looking for tree stump killers because the price of having professionals remove it costs a lot. However, most tree stump killers come in 8 to 16-ounce bottles only and range at $5-8 each. For large tree stumps or types that are hard to kill, you might be spending more in the long run. As such, choose those tree stump killers that also come in 32-ounce bottles.
Multipurpose: Sure, you are only focused on removing tree stumps now. But in between, there are also invasive plant species and unwanted vines that will emerge every now and then that you might want to be removed too. As is the case, you should consider buying a multipurpose stump killer which can kill tree stumps but also vines and other unwanted and invasive plant species.
Safety: Make sure that the stump killer that you use is not very strong that it will damage your hands even if you have your gloves on. Master the application procedure first before you dissolve the mixture. Not all tree stump killers have the same mixing procedure. Choose the brand or type with minimal risks.
Ingredients: The most potent stump killers have three major ingredients: potassium nitrate, triclopyr, and sulfuric and/or nitric acid. Check the label of your tree stump killer. If it contains all these three and more, you can depend on it for its effectiveness.
Maintenance: In this consideration, we put focus on how many times you will have to respray the stump killer to make sure that it has already died and becomes ready for uprooting. If the decaying process does not happen in six weeks and you will have to spray another round of stump killer again, you may have chosen wrong.

What are the benefits of tree stump killer?

There are a lot of reasons as to why people are turning to tree stump killers. For you to know more the facts behind this very valid question, here are the benefits of using tree stump killers.

Sheltering these insects and pests like this can endanger you and your home to infestation. They might also carry harmful diseases and other sanitary issues that you might not take notice at first.
Inhibits regrowth: As have been mentioned, the prime function of stump killers is to inhibit the regrowth of saplings. When new leaves are left growing in the stump, they could be a nuisance especially that it will be harder for the whole stump to be removed.

Things to consider when buying a tree stump killer

We have covered some of the things that must be put in mind in choosing the best tree stump killer as well as the benefits in using one. In this section, we will give a rundown of what to look out for before buying one.

1. Stump size

While we have talked about how multipurpose tree stump killers, they can only do so much when it comes to large tree stumps or to any type of stump for that matter. Sure, they can instantly kill weeds, vines, and other unwanted plants but you must be patient in applying tree stump killers on actual stumps because they take time. This is especially true for large tree stumps.

If you are working on large tree stumps, must buy in larger quantities so make sure that the one you are choosing is good for its price.

2. Time

When deciding to buy, time is indeed of the essence. You need to establish a timeframe of when you need to totally kill the tree stump so that you would know how many you should buy. It is more practical to buy a product that is specifically used for tree stumps because they can save you a lot of time.

This factor is also dependent on the first one. Of course, larger tree stumps take months, even a year to treat using tree stump killers. For smaller ones, you would see considerable change or start of the rotting process in just three to six weeks.

3. How to apply

Basically, there are two ways to apply tree stump killers. The first one is by drilling holes in the stump, exposing its insides. From these holes, tree stump mixtures are directly poured. This is to ensure that the chemicals are deeply seeped, reaching the roots for instant stump kill.

The second method is through brushing or spraying. After cutting down the tree, apply tree stump killer using a brush or by spraying the mixture on to the stump using a nozzle spray. This is the most common method used nowadays but the first method still proves to be a more effective procedure than this.

4. Toxic level

As the term implies, this factor refers to the level of toxic chemicals present in a tree stump killer. Of course, the higher the chemical content and the more chemicals used in the stump killer, the more potent it is. However, you must be wary about the possible effects of a tree stump killer on your turf as well as the other plants and trees surrounding the tree stump.

When your chosen tree stump killer is highly potent, you are risking landscape damage and death of your prized plants. Make sure that you only buy potent tree stump killers that promise safety for surrounding grass patch and vegetation.
