What Chemicals Can You Use to Rot Out A Tree Stump Quickly?

The process of rotting a tree stump is pretty similar no matter the chemical you end up using, but the chemical choice can determine the speed and the efficiency of the process. They can also determine the environmental damage to the surroundings.

The best chemical which is recommended for rotting a tree stump is Potassium Nitrate. It is most commonly sold as a wood remover and will give you the fastest results. But keep in mind that using Potassium Nitrate can be quite hazardous to the surrounding plants and to your health as well. So, you should use it carefully.

High Nitrogen Fertilizers are also a great choice for rotting tree stumps. Ammonium Nitrate and Ammonium Sulfate contain a high amount of nitrogen and will even rot the healthiest of stumps. The high nitrogen content feeds the growth of bacteria and fungi which end up speeding up the decomposition process.

Herbicides such as Spectracide and Bromide Stump-out from Amazon are some of the good options you can go for.

If you want to go the natural route, then Epsom salt and rock salt along with some cow manure or mulch are also great options. Salt will deplete the stump of the nutrients that it needs to survive.

Although these will be a little slower, they won’t be as hazardous to the surrounding vegetation.

Can You Use Organic and Natural Methods for Rotting Tree Stumps?

Yes, substances like cow manure, rock salt, and Epsom salt are commonly used for rotting tree stumps. Although their efficiency can be lower when compared to commercial chemicals, they will get the job done without harming the surrounding soil and vegetation.

They are also cheaper and easier to use in comparison to commercial products.

What Materials Will You Need?

Before you start the rotting process, it is important to make sure you have all the necessary equipment.

Make sure you have all the safety equipment especially if you are going to be using commercial herbicides such as PVC gloves, eye protection, full-sleeved overalls.

You will also need a drill and an ax or a chainsaw along with a delivery method such as a portable sprayer. You will also need a plastic tarp, preferably of a dark color to block out any sunlight.

On top of this, you will also need a herbicide such as Potassium Nitrate, a Nitrogen heavy herbicide such as Tordon RTU or Spectracide, rock salt, Epsom salt, and/or mulch.

How to Rot A Tree Stump Fast?

To begin the process, you will first need to cut down the stump to as close to the ground as possible using an ax or a chainsaw.

The next step is to drill deep holes into the stump using a drill and a large bit. Make these holes 1 inch apart and spread them across the entire area.

Fill these holes with the herbicide or salt of your choosing using a sprayer or a dripper. Make sure that the stump is not wet with rain, snow, or frost because this will reduce the absorption efficiency.

Spray some herbicide or spread some salt on the base of the stump as well, if roots are visible then cover them with the herbicide to increase its efficiency.

Once the herbicide has been sprayed, cover the stump with a tarp. The tarp will retain moisture and block sunlight which will accelerate the rotting process.

Cover the tarp with some wood chips-based mulch and water this mulch thoroughly, this will also help in retaining moisture within the stump.

After 2-3 weeks, remove the tarp and check the rotting process. If the top layer of the stump looks moist and dark, you can remove this top layer using an axe and repeat the drilling and spraying process once again to increase its effectiveness.

Will Using Harsh Chemicals Ruin Your Backyard?

If you choose to use herbicides such as Sprectracide, or Bromide Stump-out, they will be much harsher when compared to using salt or cow manure. But at the same time, they will also get the job done faster.

If you are only treating a couple of stumps with these commercial herbicides, you don’t need to worry about the long-term health of your property. Although these chemicals stay in the soil for 6-7 months, their potency reduces quite quickly. Such make sure that you don’t spray the herbicides on wanted plants or near animals.

How Much Time Can It Take for A Tree Stump to Completely Rot?

Tree stumps can take years to rot naturally. But if you are using commercial herbicides, they can get the job done in a couple of months. Keep in mind that this time frame can obviously vary depending on the species, size, and climate of your area.


You can use a variety of substances to rot out a tree stump including Spectracide, Epsom salt, salt, or cow manure. Using commercial herbicides by pouring them into holes drilled into the stump would be the fastest method for rotting them. You can expect some level of results within a couple of months of treatment.
