Best Stump Killers Buying Guide

How to Buy the Best Stump Killer

Below you will find list of important things to check before buying stump killers.

1. Active Ingredients

The active ingredients of your stump or root killer will determine the kind of applications it can be used for.

Copper sulfate pentahydrate and triclopyr are the two most common active ingredients used in the stump and root killers.

From our review, we discovered that if you want an effective stump killer, triclopyr is the ideal active ingredient for the task. If you’re looking to kill roots and algae, go for copper sulfate pentahydrate.

There are other less common, but equally effective stump killer active ingredients such as potassium nitrate.

2. Capacity

The capacity of your stump killer matters especially because the formulation is sold as either a concentrate or dilute solution.

If you intend to treat an expansive space such as a garden or a small woodland, concentrates are ideal because they can be diluted to produce several gallons of solution.

When dealing with small, one-time stump or vine removal projects, capacities in the range of 16-32 fluid ounces should be enough to get the job done.

3. Safety 

Since stump and root killers are primarily chemicals, safety should be a key priority when choosing these products.

Safety extends beyond you as the user, to other people and the environment. You should ensure strict adherence to the user guide that comes with your stump killer. Do not spray in areas that have food-producing plants.

Also, ensure you store the products away from children’s reach to minimize the chances of accidental harm.

Protective clothing such as gloves and boots are also recommended when using these chemicals.

4. Efficiency

Efficiency is a top priority when choosing a stump or root killer. We all desire the one that serves its intended purpose fast and effectively.

One way to increase the efficiency of your stump killer is to clearly follow the instructions provided on how to prepare and apply the formulation.

For instance, when treating stumps, some chemicals require undiluted application on the fresh-cut surface.

Also, there are chemicals that work best in dry conditions, thus maximizing their effectiveness.

5. Budget

The budget is another key consideration when buying a stump killer. You want to get the best value for your money.

Luckily, most of the stump killers we have reviewed are reasonably priced and affordable.

It’s always best to gauge the price of your stump killer against its quantity since most have the same active ingredients. If you can get a high-capacity stump killer for a bargain, then go for it.
