Buying Guides For The Tree Stump Removers


Tree base killers are designed with heavy-duty chemicals to effectively handle any unwanted root. As a result, you should be careful when using the product as it can have adverse impacts on your health.

It’s highly advisable to read the manual that goes with the product to know what steps you should take to ensure safety.

Different products will have different application methods. Some compounds require you to simply pour on the area you want to remove, whereas others need to have a dedicated applicator or paintbrush.

There are also some you can use to spray on the tree remains. Thus, it would help if you consider your circumstances to choose the best chemical.

Suppose your stump is near to your house or other plants. The spray options may not be suitable in this case because they can spread and affect your family’s health or other plants in the area.

There are always risks of spillage. Therefore, wear gloves when spraying herbicide and safety goggles if you’re pouring stump killer.

A face mask will be useful during the application of a powder or granule compound to a stump. It prevents overwhelming inhalation of the stump killer, which may result in negative effects on your respiratory system.

You may need to have your feet covered with a closed-toe boost to avoid burn incidents caused by toxic chemicals.

Besides, the product should be stored in a place out of your children’s reach.

Size Of The Stumps

If you have medium to large-sized tree stumps, you may need some concentrate removers designed for rotting out tree remains rather than the ones for a weed or root.

When removing a small stump or vine, the killers with capacities in the range of 16-32 fluid ounces should be sufficient.


The price will depend on the amount of herbicides you want and how useful the products are.

When you want to eliminate more than one stump, you can consider multi-buy packs, allowing you to get rid of more tree bases and save a lot of money.

The Removal Process

Liquid compound:

If you are using this type of killer, you have to cut down the stump or branches in advance. You can then pour the chemicals on the exposed sap and wait for it to do the task.

The downside of this method is that it can leak out and penetrate through your skin, resulting in harmful effects on your health. Thus, wear gloves while using.

When you want to spray it, plan ahead and avoid windy days – it is not a suggestion but a must.

Powder or granule-based products:

You may need to drill some holes deep into the base beforehand. Now, you can put the product into each hole and add water to reactivate the chemical components.

This type is more suitable for a medium-sized stump.

Besides, a tarpaulin is always crucial to keep the stump killer (both liquid and powder) protected from external elements.

The Chemicals In Stump Removers

Tree base destroyers can contain various chemicals and compounds, and the product’s usefulness will depend on them.

Below is a brief description of the chemicals in a product.

Potassium nitrate:

This compound is the most commonly used chemical, and it usually exists in the form of powder or granules.

Potassium nitrate can also be regarded as saltpeter and considered the most powerful stump removal substance.

Magnesium sulfate:

You can find this chemical in Epsom salts. It is a combination of magnesium, sulfur, and oxygen.

Magnesium sulfate can be less efficient than the first chemical, but it is more friendly to human health.


This one is an organic compound that controls broadleaf weeds and has impacts on woody plants.

Triclopyr can prevent the plant’s growth. Though it has a low toxic level, your eyes can be irritated when exposed to the product.


This substance can be highly detrimental to users’ health. However, it is incredibly potent and can eliminate most plants rapidly.


All in all, the best stump killer is Bonide Ready to Use Stump-Out, as it has almost all the basic features of a stump killer. The product features powerful sodium metabisulfite and is ready to use.

We hope with this article, you will have a clean and stump-free garden with one of the most potent stump killers on the current market!
