We’ve also included a handy review of the best off-the-shelf stump killers to help you even more. 

How to Kill a Tree Stump Fast

If you desperately want to remove the tree stump quickly, there are various methods you can use. However, it’s important to note that each option has its downsides.

Therefore, we’ve provided a little guide below to show you each approach’s pros and cons. 

If you’re a tree-stump-slaying newbie, this section will help you understand the basic methods that may work for you. However, if you want to know the best products, it’s best to skip this bit and head straight to the review section.

We’ve ranked the following tree stump removal techniques in order of speed to aid you in your decision-making process.


1. Hiring a Stump Grinder – 1+ Day

A professional stump grinder is a potent tool that quickly removes that pesky stump. The advantage to these is that these grinders don’t cause much damage to the soil structure surrounding the stump. 

But, these tools do require some physical strength and stamina, so it’s not for frail elderly gardeners. The grinder can often cost a lot to hire, too.

These tools are noisy, heavy and need you to be competent enough to safely work them. It’s important to note that they can be dangerous when not used correctly, so you must handle them with care.

2. Digging the Tree’s Roots Out – 2+ Days

If you have a small tree stump, it’s often easiest to simply dig them out. The advantage of this option is that it requires no special tools other than a spade. In addition, this method works on muscle power, determination, and perseverance.

However, the soil type and condition play a crucial role in how easy this method is. If the soil is dry, or stony, digging can be super hard work.

You can control how long it takes, of course, but you may find that the deeper you dig, the more unexpected tree roots you discover. 

Typically, the more the tree roots, the harder a stump is to remove. This is why it’s the standard gardening practice to simply leave the roots in the ground and focus on killing the stump.

3. Burning he Stump Out – 4+ Days

Burning is a brilliant option to get rid of a stump. The whole process takes approximately 24-48 hours. However, this time can vary depending on how large the stump is. 

This method involves drilling or cutting burning slots, then drenching the stump in oil or fuel to help it burn. As with fire, caution should be exercised because it is unpredictable and potentially dangerous.

4. Using a Stump Killer Product – 2-6 Months

Stump-killing products are generally made from chemical compounds that allow you to quickly rid yourself of stumps. The disadvantage to this method is that patience is required because the chemical works slowly. 

The product is a super-safe option needing much less tiring work than using a grinder, burning the stump, or digging.

There are many products on the market, such as the organic Epsom salts, RoundUp, or more practical ways that include hammering in copper nails.

5. Using Epsom Salts – 1-6 Months

This excellent mineral compound is organic, so this is a perfect option if you’re super concerned about putting chemicals on your soil. The downside to this more natural removal method is that it’s slower than using chemical compounds.

It’s not likely to be as effective as artificially made products, but it’s a pretty clean and straightforward option.

So, if you don’t have the time or energy for more laborious options and want to keep the process natural, this is the one for youTree Stump

Using a Chemical Tree Stump Killer

Even though it’s typically the slowest way to kill a stump, chemical compounds are the safest. As it’s the least laborious method, it’s the most popular, too!

Step-by-Step Guide to Applying Stump Removal Chemical

Step 1: Put on protective goggles and gloves. Using a quality saw or chainsaw, cut low to the ground as much stump off as possible. Take off any tree bark because it’s partially waterproof and can prevent decomposition.

Step 2: With the remainder of the stump, drill holes vertically, approximately ½ to 1 inch wide. Put the holes about 1-2 inches apart, tunneling as low as you can or to around 6 inches. It’s best to make the spots go deeply into the wood, beneath the surrounding soil’s surface.

Step 3: Make sure you’re still wearing your protective gear, pour your preferred chemical stump killer into the holes, and fill them. Ensure you’re following the product’s instructions before you open it.

Step 4: However, if you choose a granular option, the instructions will likely say that you need to put water into the drill holes before adding the chemicals. This will allow the compound to dissolve and soak into the stump’s wood fibers to get the desired outcome. 

Step 5: Regularly observe the rotting process, adding more chemical compound products if you need to. Typically, stumps become spongy after a few weeks using this treatment. Use a pickax or spade to dig out the wood remnants when this happens.

Accelerating Stump Rot

The tree stump rotting process depends on a few different factors that affect the time it takes. Sadly, some of these aren’t in your control. For instance, a softwood tree stump takes less time than a hardwood one.

However, if you want to accelerate the process, you can take a few extra steps.

The soil type and aeration level will affect the rotting rate because decaying requires oxygen. If the soil around the roots is well-aerated, you’ll observe a quicker root and stump decomposition. 

In addition, moisture and air temperature influence how efficient the chemical compound will be at decaying the wood. The stump decomposes in the same way that when other wood types are damp for extended periods, they tend to soften and rot.

The most important way to accelerate stump rot is by preparing the wood properly. It’s been scientifically proven that moist wood with large surface areas and excellent aeration provides the best environment for decay. But, how do you cause these conditions?

  • To reveal the largest surface area possible, reduce the stump so that it’s as low to the surrounding soil as you can. Get rid of the bark using a shovel, ax, or saw to cut off any shallow roots.

Hack, slice, or saw the stump’s surface, making deep grooves. This creates a larger surface area, encouraging rotting.

  1. Once per week, water the soil surrounding the stump and wood itself. 
  2. If you can, separate the soil around the roots, loosening the compact ground. This will add precious oxygen to the sources. 

What Is The Best Tree Stump Killer? 

Now that you know the basics about using chemical compound stump killers, you probably want to know the best products. But with the market saturated with items claiming to decompose your stump the best, which ones actually come out on top?

It can be so overwhelming to try and figure out the best one. Spending ages reading descriptions could leave you throwing in the towel on the search.

This would mean resorting to exhausting yourself hacking away at a stubborn stump, and no one wants that! 

We’ve sorted through the products and have hand-selected the items to make this process easier for you. These are high-quality options to suit those with different budgets.

And, to help you make your decision even quicker, we’ve made a pros and cons list for each.

How to Burn Out a Stump

After you’ve applied an excellent stump-killer to your unwanted wood, you might be thinking, “now what?” Well, a great way to remove a stump for good is by burning it. But, unfortunately, this wood often doesn’t burn as quickly as many people believe. 

There are several different ways to burn your stump, which we’ve listed below.

Sawing and Burning

This method requires using a pole saw or chainsaw to cut a grid into the stump. To do this, cut deeply into the wood to create 2×2 inch wooden uprights still attached to the stump. This way is brilliant for making fire reach deeply, causing the stump to burn quickly and effectively. 

Drilling and Burning

Similarly, the drilling and burning method makes the fire penetrate deep down into the stump. The difference is that you are also drilling horizontally and vertically with a 1-inch drill bit.

Again, you want to make the holes intersect, connecting the vertical and horizontal channels.

By interconnecting these holes, you’re creating brilliant airflow fuelling the fire and giving you options aplenty for where to start burning the wood. To start the fire, you can either do one of these effective methods:

  • Take strips of cloth or rag and soak them in a flammable liquid. Great liquids for this are white spirit and BBQ lighter. Once absorbed, push the rags through the holes in the wood until they’re deep inside the tree stump.
  • Douse the tree stump in a flammable liquid, letting it soak in. Pour the solution once every day for a few days to absorb it deeply by the wood.

This method is like preparing a BBQ’s coals; you have to let the wood soak in for a practical, robust, steady burn. It’s essential to cover the stump in the tarp to stop the flammable liquid from being washed away by rain during the soaking process.

Safety Warning

You must take safety precautions. Once the fire has been lit, don’t apply more flammable liquid under any circumstances! Even if the stump doesn’t appear completely alight, let it cool down for 24 hours before using the flammable liquid.

Make sure the surrounding area is safe for you to light a fire. Beware of bush fire risk. Once it’s taken hold, fire is so challenging to control. Lighting a fire in an open area after rainfall is ideal.

How to Get Rid of a Tree Stump With Charcoal

You’ll need to prepare using the previously mentioned sawing or drilling technique for this method. This will help the fire spread deeply into the stump and catch much more quickly than otherwise. You will also need a BBQ.

Bring your BBQ next to the stubborn stump and fire up some coals as though you are getting ready to cook. When the coals are glowing hot, gently and safely place them onto the stump’s top.

After you’ve done this, the coals will break up, burn and fall into the holes or grooves you’ve previously created.

Allow these hot coals to work through the stump and smolder until there’s nothing left but some ash and bits of burnt wood. 

Tips for a Safe and Successful Stump Burn

  1. Ensure the stump is dry and seasoned. It won’t be possible to set fire to a fresh, moist tree stump. Leaving it for about 12 months should be enough time for the best chance of burning the stump.
  2. Using an electric saw or hand saw, cut away the excess wood. Make the top of the stump horizontal and low to the surrounding soil. It’s best if about 4-8 inches of stump poking above the ground.
  3. Make sure you’re drilling your holes approximately 8 inches deep and 1 inch wide into the stump. Drill from the side, top, and down into the roots to create the desired hollowed-out area that allows flames to thrive. This will help the air to penetrate the stump, oxygenating the fire.
  4. If you are drilling over a prolonged period, make sure you cover the stump in tarp between sessions. This will stop any rainwater or sprinkler water from dampening the wood.
  5. Using a chainsaw to fray the stump’s edges will create a tinder-like environment. 
  6. If you’ve drilled holes, fill them with flammable liquid. It’s best to allow the stump to soak in this fluid. Alternatively, rags saturated with flammable liquid will serve as a wick that draws the fire deep into the wood.
  7. Put a bottomless metal bin around the entire protruding stump if you can. This will help stop the fire from spreading.
  8. Oxygen is crucial if you want the stump to burn super quickly with intense flames. Using a reversed vacuum cleaner or leaf blower will speed up the burning process a lot. Please be wary of any floating embers that will likely fly out from the fire and land nearby.
  9. Once the fire has taken on the stump, it should eventually turn into a super slow burn. The inner cavity holes will allow the fire to burn well from the inside to the outside. This method will take approximately 24 hours to complete.

Will Copper Nails Kill a Tree Stump?

Yes, over time. Copper negatively affects a tree’s growth metabolism, eventually killing them. However, a small and medium-sized tree stump can be destroyed easily using copper nails.

This prevents you from having to introduce harsh chemicals to your ecological system. Below, we briefly describe how you can use them.

For this method, you only need pure copper nails. It’s best to use 4-inch nails that penetrate deeply into the stump.

We recommend using around 12 nails to kill a stump around 6 inches or less in diameter. The general rule is to use 1 copper-nail per inch or so as you hammer around the stump’s circumference.

How To Use Copper Nails To Kill a Tree Stump

Step 1: 

Hammer the copper nails vertically profoundly into the tree trunk. Put them in as low as possible so that they’re as close to the roots as you can get them. Hammer the nails so that there’s approximately a 1 or 1.5-inch gap between them, following the stump’s circumference.

For small trees, reduce the wood, so it’s as low down to the ground as possible, then follow the above instructions.

Step 2:

Cut off visible roots and sprouts. This cleverly tricks the stump to take its nutrients from the toxic copper nails rather than the surrounding soil.

Step 3:

It’s essential to leave the nails in the stump for as long as you can. Small trunks that are approximately 3 inches wide will decompose within a month.

Whereas, for medium-sized stumps, the nails can take up to 3 months or more to work their magic. However, you can observe the tree trunk decaying within weeks. 

Step 4: 

Once you realize the stump has completely dried, you can start to remove it. Take out all the copper nails first; spikes or nail pullers are helpful to do this.


And there you have it! There are many different ways to remove a tree stump, each with its own benefits. So, follow our guide to get that stubborn stump out of your life for great results!
