Reviews by This Old House Reviews Team 10/05/2022 2:05 pm

Cutting down trees in your yard is a great way to improve the natural lighting for other plants and make way for new trees to grow. If you’ve removed a tree in your yard, you know how pesky its leftover stump can be.

While you could leave it alone, it could start to grow, sprouting annoying shoots from its roots, or it may take years to naturally rot and decompose. Try the following techniques to kill the tree stump and remove it from your yard or find a tree removal expert to take care of it for you.

Home Remedies for Tree Stump Removal

Here are a few ways you can get rid of a tree stump before getting your hands dirty with physical removal.

Epsom Salt

This is a common DIY method for killing tree trunks, as it accelerates the decomposition process to 6–12 months, as opposed to three to seven years for natural rotting. Epsom salt contains magnesium and sulfur, which are beneficial to plants but deadly in large quantities. Overdosing the stump with Epsom salt pulls the moisture out of it, killing it and accelerating the decaying process.

Here’s how to use Epsom salt to kill a tree stump:

  1. Drill deep holes in the stump about an inch wide with a power drill and a wide drill bit.
  2. Sprinkle the stump with water after covering the top of the stump with Epsom salt.
  3. Cover the stump with a tarp to keep the rain from washing away the substance.
  4. Repeat this process every few weeks to ensure its success.

If this process is successful, the stump will die within two to three months and be close to full decay after a year. This is a great solution for homeowners who want a slower, natural approach to killing their tree stump.

Rock Salt

Similar to Epsom salt, rock salt can help kill and decay a stump with minimal effort. Here’s how to kill a tree stump with rock salt:

  1. Drill holes into the stump.
  2. Pack the holes with rock salt.
  3. After all of the holes are packed and the stump is covered in salt, pour soil and mulch over the stump.
  4. Then, pour water over the mulch—this will dissolve the salt, help the roots absorb the solution, and pack the soil.

Keep watering the stump every few days for one to two months to keep the stump moist with the saltwater solution, promoting absorption and the growth of fungi that can accelerate the stump’s decomposition. You can also add a potassium nitrate fertilizer to further support the growing fungi.

Plastic Bag or Tarp

Perhaps the easiest method to kill a tree stump is forcing darkness on it. Without sunlight, the tree stump will die, accelerating the decomposition process. Rotting should start to take place in two to three months.

Here’s how to kill a tree stump with a plastic bag or tarp:

  1. Similar to other methods, cut the stump as close to the roots as possible with a chainsaw, hatchet, or handsaw.
  2. Cover the stump with a black trash bag.
  3. Weigh the bag down with heavy rocks or bricks. For a smaller stump, use a dark-colored bucket or container to cover the stump.

This technique requires little to no effort, but it can be slower compared with the physical removal methods.

Boiling Water

You don’t need to purchase any substance or solution to try this remedy—all you need is hot water.

  1. Expose as much of the stump’s root structure as possible.
  2. Drill holes into the roots and on top of the stump—this will help the scalding water reach as much of the root system as possible and kill the roots with heat.
  3. Once all the roots are exposed, pour boiling water over them. The heat from the water will shock the root system, severely damaging it and killing it.

Once the stump and roots are dead, the natural decomposition process can begin.

Techniques To Physically Remove a Tree Stump

If you have the time and resources to use physical methods to kill and remove your tree stump, consider the following techniques. Compared to home remedies, they are much quicker but take a bit more effort, tools, and money to perform.

Use Fire To Kill a Tree Stump

Use some kindling or kerosene to burn the stump so that it doesn’t protrude from the ground. This method will kill the tree, but it won’t completely get rid of the tree roots and stump. Keep in mind that this may not be an option if you live in an area with a dry climate that’s prone to wildfires. Check with your local fire department to see if burning a tree stump falls in line with the local fire code.

Once you have approval to burn your tree stump, there are a few ways you can move forward. You can drill holes into the trunk, pour kerosene into each hole, light scrap wood on the surface of the stump, and carefully monitor the wood as it burns. This method is slower, but it burns the wood from deeper within the stump.

You can also cut criss-cross lines in the wood that are about five to six inches deep with a chainsaw, then simply light some kindling on top and monitor the stump until it’s burned down below ground level.

Dig the Tree Stump Out of the Ground

Digging out a tree stump is one way to remove it from your yard, but it can require time-consuming work that can be potentially destructive to your yard or garden. This method allows you to remove as many tree roots as possible and ensure that the stump doesn’t continue to grow. To save time and effort, consider hiring a professional with digging equipment to handle the job.

Here’s how to dig a tree stump out of the ground:

  1. Dig around the stump, exposing as many roots as possible.
  2. Use a chainsaw, hatchet, or handsaw to cut the larger roots. As you continue digging, you may find smaller roots that can be cut with clippers or loppers.
  3. Once you’ve cut all of the roots around the stump, lift and remove the stump from the ground.
  4. Fill the hole with dirt and cover it with topsoil or mulch.

Note: This process can take multiple hours of labor, depending on the size of the tree stump and the root structure.

Grinding the Tree Stump

This is the quickest method for killing and removing tree stumps. It involves hiring a tree removal specialist or renting a stump grinder machine to break apart the wood in the trunk and tree roots. Typical prices for this job are around $100–$400. Stump grinder machine rental costs typically fall between $80 and $150 for a four-hour window.

To grind a tree stump, start by trimming the stump with a chainsaw, digging around it and removing any rocks. Then, use the machine’s cutter blade to chip away at the wood and cut any roots that are connected to the stump. This process can take anywhere from two to six hours depending on the size of the stump. Once you’re finished, spread dirt in and over the hole, adding topsoil or mulch if desired.

What To Avoid When Killing Tree Stumps

Here are a few factors to consider when removing or killing tree stumps to ensure safety and effectiveness:

The Bottom Line

If you’re trying to remove a tree stump from your yard, try one of the above methods. While we recommend the DIY techniques if you’re not in a hurry, renting a machine or hiring a professional to help grind the stump is the fastest solution.

How to Kill Tree Roots

Dark-Colored Bucket or Heavy-Duty Black Trash Bag

Killing trees’ annoying roots is not as easy as chopping down a tree. Even if you cut down trees that grow in shade to the ground, new growth from the stump or plant roots will continue to bud, which will eventually turn back into mature trees again. To get rid of the tree stump, a dark trash bag or bucket can work as a homemade tree root killer.

Just cut a big stump close to its base and cover it with the trash bag. For a smaller tree stump, you can use the dark-colored bucket for cover. After you have blocked moisture and sunlight, use a weight to keep the cover in place. Expect results in approximately two months or less.

You can also employ this method for a weed killer that will not kill grass. Cover weeds with plastic or a bucket. It may take a while for weeds to shrivel and die, but you won’t harm surrounding plants or grass that you want to keep.

Epsom Salt

We all know that Epsom salt has many benefits for health and wellness. But aside from that, there are many fantastic Epsom salt uses in the garden.

Epsom salt contains sulfur, as well as magnesium that can aid in producing a healthy environment for plants and trees to grow if given in small amounts. However, if used in large quantities, Epsom salts can yield deadly results for all types of evergreen trees and other plants.

Epsom Salt Tree Root Killer Recipe

tb1234

To make the recipe, fill the bucket with warm water. Add Epsom salts and stir until the granules dissolve. Use your garden trowel to dig the soil around the stump to reveal its base and root system as much as possible.

The more parts that are visible, the higher the chances of killing the stump and prevent future growth. Drill holes two-inches-deep in four corners of the stump, as well as in some roots.

Pour the mixture into each hole. Use all of the solution to saturate the stump. You can make more solution if the stump is too large.

After a week, fill the holes again. Repeat if necessary, or until the wood completely dries out. Once it’s dry, you may cut out the dried stump. This is the perfect homemade root killer for sewer lines.

Make a smaller batch of this recipe, add several drops of Dawn dish soap and put the mixture in a spray bottle to use as a natural grass killer spray for weeds or grass that are growing in unwanted areas. Be sure to apply it when no rain is expected for several days for the best results.

Rock Salt

Rock salt has numerous uses aside from melting snow in walkways, roads, and highways. Its active ingredient, sodium chloride, has a destructive effect on tree roots and stumps.

The sodium chloride draws out the moisture, consequently drying out the tree stump. A tree root without moisture lacks nutrients, which will eventually lead to its death.

Rock Salt Recipe

This method works by packing rock salt into holes you’ve drilled in various parts of the tree stump. To make the drying process faster, you should also pour copious amounts of rock salt around the base of the tree stump. A two-inch layer of rock salt will be sufficient.

Add hot water for the rock salt to leach into the soil. Cover the tree stump with soil and mulch. Let it sit for one and a half months or until the stump decomposes. You can start the removal process once the stump has decayed fully.

Undiluted White Vinegar

When you’d rather use a safe, non-toxic, homemade tree stump killer instead of chemicals, vinegar is a good option.

In small amounts and low concentrations, gardeners can use horticultural vinegar on plants for germination. But if sprayed frequently, and in large volumes, undiluted white vinegar can be an effective homemade tree root killer.

To make this process work, select a sunny, dry day and fill a clean spray bottle with undiluted vinegar. Sprinkle the vinegar thoroughly into the shoots that are growing back from the stump or tree roots. Repeat the process until the leafy top growth that supplies the roots with nutrients die, eventually killing the rest of the tree roots.

Foaming Root Killer

Foaming root killers also serve as effective drain cleaners, especially among professional plumbers. They use commercial products such as RootX, copper sulfate crystals, and tree root killers that contain various chemicals such as a herbicide called dichlobenil to clear drain pipes, sewer lines, and septic tanks of tree roots.

Foaming Root Killer Recipe

If you do not wish to use commercial tree root killers, you can make a natural tree root killer by using the recipe above. Mix the ingredients on the list. Immediately flush it down into the lowest toilet in the house.

The solution will start to fizz, and this fizzing action will fill the pipes, causing the salt to leach on the roots. The obstructing roots will die, but the results won’t be immediate because it will take time before the dead roots get washed away.

Why Make a Homemade Tree Root Killer?

Aside from being unsightly, tree roots grow deep below ground, searching for moisture and nutrients. They crawl through the soil, force their way towards sewer pipes and collapse them, eventually damaging the entire pipeline.

If you let root intrusion rule over your yard, it will cause costly damage, as you will need a professional plumber to fix the issue. Fortunately, there are many affordable and simple ways to kill tree roots. Without spending too much, you can make a homemade tree stump killer.

folk remedies from the root without uprooting, how to destroy and how to remove it with saltpeter, how to kill it chemically

The formation of stumps and roots in the garden is due to the fact that the trees naturally die off. And it’s good when there is one inconspicuous stump on the site, which does not particularly disturb the aesthetics of the site. But when there are several of them, the gardener begins to think about how to get rid of the problem. And to do this today is quite real quickly and efficiently. There are many effective methods that everyone can use.

Harm from tree roots in plot

very often people want to fill their garden with new trees. But here they have such an obstacle in their way as old stumps. Another need to clean the stump is due to the fact that the tree is in disrepair. In addition to this, the stump is a real obstacle to creating a landscape composition. All of these situations require the immediate removal of the stump from the garden. You may also be interested in learning how to get rid of the onion fly in the garden.

Ways to remove roots - how to quickly remove and remove them

Today, you can remove the roots left after a tree by chemical, mechanical methods.

Chemical method of uprooting - using saltpeter

This method can be classified as universal. It is very often used by gardeners when dealing with stumps on their site. The essence of the method is that wood residues must be burned, but only before that they are impregnated with a strong oxidizing agent - nitrate. You can also use saltpeter when destroying gout in a summer cottage.

Thanks to this unique tool, it is possible to burn the stump, and this can be done not only with the above-ground part, but with the roots. Before carrying out the manipulation, it is necessary to perform a number of preparatory measures:

  1. Drill as large a hole as possible in the tree, using the thickest possible drills. Such actions should be carried out at the end of summer or at the beginning of autumn.
  2. Insert saltpeter into the hole made up to the top . For these purposes, you can use both potassium and sodium composition. After that, pour saltpeter with water. This will allow for better impregnation of the wood.
  3. Cover the top of the hole with pre-prepared wooden plugs. You can also use plastic wrap, which is tied tightly around the tree trunk.

Every gardener has encountered such a problem on his site as a dandelion, but this information will help you understand how to get rid of dandelions on your site.

On the video - removal of roots with saltpeter:

Leave the prepared stump in this form until next summer. Over the entire period of time, its root system will feed on saltpeter and dry out. It is necessary to make a fire near the stump. It should burn until the complete destruction of the remnants of the tree.

You may also find it useful to know how to deal with field bindweed in your garden.

When the top cut of the stump is centered on the same level as the ground, additional holes should be made in it. Pour kerosene or gasoline there.

Ignite this combustible mixture so that combustion is maintained throughout the volume. As soon as the roots are completely burned out, the place where the stump grew is dug up and covered with soil.

How to dig up and uproot stumps and roots

This method is labor intensive. It is realistic to perform it only under the condition of a shallow location of the roots and the average size of the trunk itself. To perform this operation, you need:

  1. Make trench near the stump. Its depth will be 1 m.
  2. Using a bayonet type shovel and an ax, all side branches of the root system must be removed.
  3. With the help of a crowbar, which must be brought under the stump, it is loosened from one side to the other.
  4. In addition, it is necessary to constantly trim the exposed lower processes of the root system with a shovel.
  5. Once the root branches have been removed, the remains of the stem are free and removed from the hole.

It is also worth learning more about how to get rid of hops on the site, and what are the most effective means.

On the video - digging and uprooting:

Even on the plot, uprooting can be done using special equipment. When the trunk diameter is less than 30 cm, then a rope must be used to remove it. Pick it up by the stump and use a tractor to create traction. Using this method, cutting down the tree is carried out very high - at least 1 m above ground level. This will firmly fix the cable to the bottom of the stump.

If the equipment cannot reach the stump, then you can use a mini-tractor or a winch. But then chopping needs to be done with larger lateral processes. Do this to a depth of 30 cm. And the most successful option would be to dig near the trunk to a level of 0.5 m. Another problem in the garden is maple, and what chemicals can be used to get rid of it are indicated here.

How to remove and destroy by crushing stumps

To remove a stump, you need to use special devices with which you can crush wood. Most often involve forest cutters. With the help of such a cutter, it is possible to grind wood to a depth of 30 cm in one go.

The main disadvantage of this method is the high cost of the device. In addition, it is not advisable to buy cutters and a tool for single stump removal. It may also be useful for you to learn how to get rid of thistle on the site forever, and for this you should follow the link.

Using salt to get rid of the roots

This is another option for chemical removal of stumps on the site. The fact is that salt is the simplest catalyst for the process. And it is worth using table salt.

Make a recess in the stump 8 cm deep and 10-15 mm in diameter. The more holes there are, the better. Pour salt into the holes made, and crush the earth on top. The result of such processing will be the complete destruction of the remains of the tree. But it will be possible to observe it only in a year. A very interesting issue is the fight against wood lice in the garden plot, but how all the work to destroy it is carried out is described in the article at the link.

Uprooting with urea

This method is identical to where saltpeter or salt had to be used. To begin with, make holes in the stump with drills. Send urea into the resulting recesses. Pour water over the top, and then wrap the stump with polyethylene. After 1-2 years, it will be possible to remove the remains of a decayed stump, and scatter fertile soil in this place.

To fit 1 kg of urea, approximately 30 holes will need to be made. At the same time, their diameter should be about 1 cm, and the depth should be 30 cm. The consumption of urea for the removal of a medium-sized stump is carried out by analogy with saltpeter. And here's how to get nettles out of the area, and what chemicals should be used. this information will help you understand.

The advantages of this method include:

This method has its drawbacks:

Removing stumps on your property is not easy. This is a rather painstaking task, but nevertheless it is carried out. In addition, each gardener will be able to determine for himself the appropriate option, taking into account the size of the stump and his capabilities. If you have nowhere to hurry, then you should use chemical methods. If the removal of stumps is an urgent matter, then you will have to spend money on the purchase of special equipment or tools.

Destruction of the roots of trees and bushes: the best means and methods

Renovation of the garden is invariably accompanied by cutting down old trees and planting new ones. But after that, one problem appears: stumps remain in place of the removed plants, which not only spoil the appearance of the garden, but also reduce the potential area for new plantings.

This article will describe the main ways to destroy the roots and stumps of trees, and step-by-step instructions for mechanical and chemical removal of wood residues will help clear the garden of old stumps.

Why tree roots need to be removed

Removing an old stump has not only aesthetic but also practical value. As a rule, they appear on the site after the old tree has already been cut down and disposed of. Just removing a tree from the site is easy, while removing its overgrown roots and large stump is much more difficult. Many people use the old proven mechanical uprooting, but there are a variety of chemicals on the modern horticultural market that make this process much easier.

See also: Do-it-yourself drip irrigation

If the root and part of the trunk do not bother you, you can turn it into a kind of garden decoration by planting flowers inside it or decorating it in any other way you like. However, there are times when destruction is not just a whim, but a necessity. This happens if the tree was cut down due to illness. If even a small part of it is left in the ground, it can become a source of infection for the rest of the trees in the garden. In addition, the remains of an old plant occupy a usable area, because in their place you can plant a young tree or shrub, which will bring a crop in the future.

Preparing to destroy the roots of trees

Before you start removing the roots, you should decide on the method you will use for this. Wood residues can be destroyed mechanically or chemically.

If you prefer to manually uproot part of the trunk, you will need a saw, a shovel and an axe. In this case, you will first have to dig a hole around the stump, chop or file its roots and gradually, piece by piece, remove the wood from the soil.

Note: The mechanical method is considered obsolete not only because of the high labor costs, but also because some large specimens are difficult to manually remove, and the remains can only be uprooted from the soil with the help of machinery.

The chemical method is considered more modern. The remains of wood are simply treated with a special preparation that accelerates the process of fiber destruction. As a result, in a short time, the remains of the trunk begin to crumble, and you just have to remove it.

Figure 1. Preparatory work

Depending on the chosen method, you will need some preparation (Figure 1). With mechanical removal, you need to dig a hole around the trunk in advance and prepare all the necessary tools, and in some cases, rent special equipment. If you opted for the chemical method, you will need to buy special treatment products, as well as prepare a spray gun and protective clothing.

Methods for removing tree roots

As mentioned above, roots and stumps can be destroyed mechanically and chemically. Since they are fundamentally different from each other, we will look at the features, advantages and disadvantages of each of them in more detail so that you can choose the right one for yourself.

Mechanical uprooting

This method is considered the oldest, since the process uses tools with which the roots are filed, and the stump is simply uprooted from the ground. A more modern mechanical method involves the involvement of heavy equipment (excavators, bulldozers or special pullers), but, unfortunately, not everyone can pay for the rental of such equipment. In addition, it is far from always possible for heavy equipment to enter the site.

Figure 2. Mechanical uprooting

If you don't want or can't use heavy equipment, you can also remove the stump manually. This will require some preparation. First, the remains of the plant must be freed from the surrounding earth by digging the soil with a shovel. Secondly, you need to prepare in advance the equipment with which the trunk will be removed from the ground (Figure 2).

Mechanical uprooting is carried out as follows:

  1. After the stump is freed from the soil, it must be tied with a cable attached to the winch. It is better to fasten the cable immediately under the saw cut so that it acts as a lever when tipping over. The winch can be tied to a regular car.
  2. If it is not possible to use a winch, the frame can be removed by cutting off the remains of the roots with an ax or cutting down with a saw.
  3. Once the trunk is free of lateral roots, it can be easily swung and removed.

This method is the cheapest, and with some effort, a large root can be uprooted in a day. However, this method is accompanied by significant labor costs. In addition, if you plan to carry out construction on this site, a mechanical removal method will not work for you, as the remnants of the roots may remain in the ground.

Chemical removal of tree roots

Chemical stump removal is simpler and more modern, although it has certain peculiarities. As a rule, saltpeter is used to destroy wood residues - a chemical with a powerful oxidizing effect, which quickly destroys not only the aerial part, but also the roots (Figure 3).

Removal of roots with saltpeter is carried out as follows:

  1. At the end of summer or beginning of autumn, several holes are drilled in the trunk. For this purpose, it is better to use the thickest drills so that the diameter of the holes is large.
  2. Potassium or sodium nitrate is poured into the holes obtained and poured with plenty of water. The liquid will dissolve the chemical and it will penetrate the wood fibers faster.
  3. The top of the trunk should be covered with pieces of wood or covered with foil, tightly tied to the trunk. This will prevent chemical vapors from escaping, and the destruction process will be more active.

The stump prepared in this way should be left until next summer. During this time, saltpeter will saturate not only the trunk, but also the roots. After that, you need to either pour a small amount of kerosene on the remains of the tree, or light a fire around the stump. The tree will begin to smolder, and all you have to do is remove its remains and dig up the site.

Note: It is important to consider that this method is not suitable for areas with peaty soil, since the roots soaked with saltpeter after ignition can cause a fire in the deep layers of the soil.

This method is good because it requires minimal physical effort, and all the remains of the tree will be completely removed. An exception can only be thick and deep-lying roots, but they will be destroyed so much that they will not be able to give young shoots.

Figure 3. Chemical destruction with saltpeter

But when using saltpeter, it should be borne in mind that in large quantities it negatively affects the fertility of the soil, so it will not be possible to grow fruit and vegetable crops in this area for several years.

How to remove the roots yourself

Another easy way to remove roots and stumps with your own hands is with the use of urea. This method is also considered chemical, but its advantage is that even large stumps can be removed quickly and with minimal labor.

Preparation of the barrel for removal is similar to the saltpeter method: large holes are drilled in the barrel, into which urea (urea) is poured. Each hole is filled with water, and the saw cut is tightly covered with a film. After 1-2 years, both the trunk and the roots remaining in the soil will completely rot and turn into fertile soil (Figure 4).

Figure 4. Chemical uprooting with urea

The main advantage of this method is considered to be low labor costs. But it should also be borne in mind that when using urea to remove stumps, all wood is destroyed: not only the trunk, but also the roots that go deep into the soil. In addition, after such treatment, the soil is not polluted with chemicals, remains fertile and suitable for growing other crops. Of the shortcomings, only a long period of stump removal can be distinguished: it can take 1-2 years to destroy large specimens, but if you want to maintain high soil quality and not make serious physical effort, this method will be the most suitable.

Safety when removing roots and stumps

When using any chemicals to destroy tree residue, safety rules must be strictly followed. First of all, for processing, you need to wear gloves and a protective suit. This requirement applies not only to saltpeter, but also to safer urea, which should also not be touched with bare hands.
