How to grind down tree roots
Tree Root Removal: A How-to Guide
You thought you were done with that tree when the chainsaw fell silent. Not so fast. You still have to deal with tree roots. Tree roots are an entirely different beast. Depending on the size of the tree or the reason for the removal, you may even need to call in professional help to remove the tree roots in your yard.
In this how-to guide, we’ll cover the things you need to know about removing tree roots, the conditions you might face, tools you can use, and even when you might need to throw in the trowel and call for expert help.Why Should You Remove Tree Roots?
The most obvious reason to remove tree roots is that there is a stump in your yard that serves as a reminder of a tree that once stood there. And like the rest of the tree, you need it gone for one reason or another.
But that’s not always the case. You may, in fact, want to save the tree, but eliminate pesky roots that are cracking your sidewalk or clogging up the sewer line. Whatever the reason, we’ve got you covered. So let’s get started.Removing Tree Roots After Tree Removal
Taking out tree roots can be a big job, especially if it was a big tree. Its underground root system can spread 20 feet deep, sometimes even more in the right conditions. To remove tree roots that are left after taking down a tree, in most cases, you have three options:
- Physically remove the roots yourself
- Treat the roots with chemicals
- Hire a professional tree stump killer
Physically Remove Tree Roots on Your Own
Physically taking out a tree stump and its roots is the fastest, but most laborious way to get rid of it. Tree stump removal and taking out the tree roots on your own generally involves either digging them out or using a stump grinder. It depends on the type and size of the tree roots you are dealing with. This type of DIY project works best with smaller stumps and roots.
Digging Out Tree Roots
First, call the utility company to make sure you aren’t digging around water, sewer, or other underground lines.
To dig out the roots, you’ll need a few supplies:
- Grub hoe
- Root saw (possibly)
Here’s how to dig out tree roots by hand:
- Using your spade, you’ll want to dig out the soil that surrounds the roots to expose them. Pull out any loose roots until no more loose ones remain.
- Dig out the dirt surrounding the ones that are still intact and cut through them using your loppers. Try to cut far from the root ball.
- Next, use the grub hoe to lift out the cut roots. Pull additional ones out by hand if you can. Push the stump back and forth to loosen the roots and continue to cut and pull roots until you can remove the root ball from the soil. A root saw may be needed if the roots are too thick for the loppers.

In some cases, digging out the tree roots may prove difficult. But there is another option to physically remove them, and that is with the use of equipment. Stump grinding a pesky tree trunk is work, but you can eliminate it quickly, and even create some fresh wood mulch in the process.
If you use this method, you’ll need:
- You’ll need to rent a stump grinder
The average cost to rent a stump grinder is between $100 and $400. They can be found at your local home improvement stores such as Lowe’s or Home Depot. Or you can rent one from an equipment store such as Sunbelt.
Pro Tip: Because of the debris involved, it’s important to wear the right safety gear. This includes fully covering your body with pants, a long sleeve shirt, and protective headgear and glasses.
- Use your chainsaw to trim the trunk as close to the ground as possible.
- Dig up any rocks and debris around the trunk that could damage your grinder.
- Once the trunk and roots are prepped, you can drive the grinder onto the stump and start grinding it down.
Depending on the size and location of the tree, you’ll grind down anywhere from 2 to 4 or more inches. After you’ve completed this, use your shovel once again to dig up tree roots that were attached to the trunk.
Once you’ve completed the process, it’s time to treat the area. You can do this by shoveling or raking the loose wood chips onto the area where the stump was. If it is in a grassy area, also add topsoil and grass seed. If not, use mulch to help cover it.
Continue to check on the hole and treat it until it becomes a natural part of the yard.
If you’re contemplating how to remove the stump before you worry about removing the roots, check out our guide on 5 Ways to Remove a Tree Stump.
Treat the Roots With Chemicals
If you choose to treat the tree’s roots, there is a chemical herbicide option, which works fast to eliminate roots, or the more natural option of using rock salt, which is equally effective but takes longer. You can also use Epsom salt or another highly concentrated form. Table salt won’t do the trick.
Remove Roots Using a Chemical Compound
Treating chemically is easier, but will take longer.
You will need:
- Water hose
- Garden sprayer or paintbrush
- Herbicide – a glyphosate herbicide with an active ingredient concentration of at least 41 percent is best.
Pro Tip: Wear safety goggles or a face shield, a dust mask and hearing protection while working with the saw.
- Use the saw to make a fresh cut across the tree stump.
- Saturate the tree’s outer layer (just behind the bark) with water. The water will help distribute the herbicide to the tree roots.
- Next, mix the glyphosate herbicide with water to create a 50/50 solution, and use your garden sprayer to saturate the outer ring of the tree stump with it. Try to avoid getting the solution on the grass or any nearby plants.
Once the chemical treatment is applied, you just wait. It will take about two weeks for the tree roots to completely die off.
Remove Roots With Rock Salt
It will take a few months and a few applications to get the job done.
First, you’ll need:
- A drill
- Drill bit that’s 3/8 of an inch in diameter.
- Rock salt
Pro Tip: Take care when handling rock salt and always wear gloves, because when it contacts your skin, it can cause “salt burns.”
- Drill several holes in the tree stump that is about three to four inches deep. If there are any exposed roots on the ground, drill holes in these too.
- Fill each hole completely with the rock salt, then add enough water to cover the hole without any spilling out and causing damage to other vegetation. Do this several times each month.
The rock salt will rob the roots of any water and after a few months, your tree roots should be dead.
How To Remove Roots Inside Your Plumbing Pipes
Clogged plumbing due to tree roots is a common issue for homeowners. But if you take proactive measures, you can easily correct this problem with just a little rock salt.
- Pour about half a pound of rock salt at a time into your toilet and flush until it goes down the pipes.
- Repeat until you’ve used a full two pounds.
- Then close off the bathroom and don’t let anyone in the family use that toilet for about 8 to 12 hours.
The rock salt will kill the tree roots by robbing them of their moisture. Repeat this monthly for ongoing maintenance.
Tree Root Removal Without Harming the Tree
Sometimes you love the tree in your yard but hate the roots that are tearing up your sidewalk or clogging up the plumbing. So what do you do about them? Can you eliminate these roots without harming your tree?
The answer here is yes. You can trim the roots back and you can take measures to prevent them from coming back in unwanted areas. First, you’ll need a water hose, hand trowel, and a wheelbarrow or tarp to temporarily place the dirt, root saw, and material to create a root barrier (plastic, metal, or concrete).
With supplies ready, start by using your hose to soften the ground with water. You want the ground to be damp, but not soggy. Next, use the hand trowel to loosen the soil and feel out the roots. Remove the soil in and around the roots and place it in the wheelbarrow or on the tarp. It’s best to use your hands for this.
Once the area is clear of dirt, cut the roots using your root saw, but be careful. A few guidelines to follow so that you don’t damage the tree are:
- Don’t cut more than one-third of the roots.
- Measure the tree trunk’s diameter, then multiply it by three. That’s as close to the trunk as you want to cut.
- Cut only those roots smaller than the size of a fist.
- Do not cut any more than 25% from one side.
After you’ve trimmed the roots, dig a trench between them and the area that you don’t want them to go. Create a barrier at least 12 inches high and 10 inches long using a material like metal, plastic, or concrete, then cover it with soil. Pat or compact the soil down and spray with water to wet the ground.
Hire a Professional
There are several reasons that you may want to hire a professional tree service to remove your tree stump. For example, if you don’t want to mess with the physical work of digging or grinding the stump yourself, and you don’t want to wait weeks or even months for it to go away, then it’s a good idea to let a pro take care of it for you.
In many cases, if you are having the tree professionally removed, then you can hire the same company to take out the stump too — for an additional fee.
According to Bates Hite, the owner of Tree Stump Masters in Atlanta, he’s seen homeowners do all kinds of crazy things to remove tree stumps, even lighting them on fire with charcoal. And he warned that the stump grinders you can rent at the local home improvement store are not powerful enough for larger roots.
“You can’t rent a big enough piece of equipment to get the job done right on a large tree stump. You need to go deep, and you need a big machine,” he said.
On average, the cost of tree root removal by a professional tree removal service can range from $250 to $350 depending on the size and location of the tree stump.
What is the Easiest Way to Remove Tree Roots?
While labor-intensive, the easiest way often is to dig around the stump, exposing the roots, then using a chainsaw or hatchet, cut the large roots. You can use gardening shears to cut smaller roots.
What will Dissolve Tree Roots?
Rock salt or a glyphosate herbicide with an active ingredient concentration of at least 41 percent can dissolve tree roots.
What Tool Removes Tree Roots?
Depending on the size of the root, you can use gardening shears, a chainsaw, a hatchet, or a handsaw to cut away roots.
What Should I Do With a Tree Stump?
If you have a tree stump, then it should all be removed to avoid it developing health hazards like mold or fungus. The dead tree can still spread disease to your healthy ones if left in place.

How To Remove Roots After Tree Removal
Sometimes tree removal is the only viable solution to maintaining the health and safety of a yard or other outdoor space. Once the tree is removed, the stump and the connecting roots underground are left behind, which can be a significant problem and one has to consider how to remove roots after tree removal.
Typically, tree removal involves clearing up the surrounding space, identifying the best way to fall the tree, and then using the appropriate equipment and technique to cutting it down to its stump.
Left behind stumps are a nuisance and should be removed immediately for the following reasons:
- The stump can be a tripping hazard with the potential to cause serious injury.
- The presence of the stump can hurt the overall aesthetics of the landscape.
- Sometimes, the roots connected to the stump continue to grow after the tree removal and may end up wrapping around pipelines, lifting patios, or even damaging the foundation of the house.
- A new tree might grow around the stump left behind, which might be harder to remove than the original one as shoots keep returning. These new growths can often suck up essential moisture from the soil adversely hurting the health of the landscape.
- The stump and the roots will rot over time and become a breeding ground for many pests, which can spread to other healthy plants, and even find their way indoors.
Due to all of the aforementioned reasons, it is important to get rid of the stump and roots once the tree has been removed.
One popular method of getting rid of the stump is known as stump grinding. It involves the use of a powerful machine, known as a stump grinder that grinds the stump into tiny wooden chips.
Stump grinding offers numerous benefits, which include being quick and non-invasive, being cheaper than full stump removal and offering nutrient-rich mulch that can be used to improve the health of the soil.How To Remove Roots After Tree Removal and Stump Grinding
Being non-invasive, stump grinding does not actively remove the underground roots. Once the stump is ground out, the roots die and decay, becoming part of the soil. As a precaution, the roots connected to the base of the stump are often severed using shears to ensure there is no regrowth. This natural process is a time-consuming one with roots sometimes taking up to 10 years to decay completely.
Hiring a tree service pro like Hidden Oak Tree Care can immediately solve your tree and root removal needs. However if you have more time, there are several other options available for getting rid of roots after stump grinding:
- Dig Out The Roots: Have your stump grinder go a little deeper into the ground when grinding the stump. Once the stump is ground 6 to 8 inches into the ground, it becomes much easier to simply dig and pull out the roots, getting rid of them completely. This is one of the most comprehensive means of getting rid of roots and the associated problems with continued root growth.
- Chemical Herbicides: Another method that can be used is to treat the left-behind roots after stump grinding with powerful chemical herbicides found in stores. These powerful chemical agents work effectively to kill the roots quickly, which can then decay and become part of the soil. We don’t recommend the use of chemicals, however, because they can leach into other areas of your yard and harm your plants, and potentially your animals.
- Epsom Salts: If you are avoiding chemicals, then you can use the more natural route of using Epsom salt or any other concentrated form of salt to kill the roots. While it will require several applications over a few months and will be slower than its chemical counterpart, Epsom salt will be equally effective in killing the roots.
Stump grinding is the best way to get rid of the underlying roots of any removed tree. It is also the best way to get rid of the stump’s roots and certainly beats waiting for the roots to naturally decay.
If you are unsure of which method to use for your particular situation, it is always a good idea to seek the opinion of the professionals at Hidden Oak Tree Care. We can advise how to remove roots after tree removal and will handle the full project to your satisfaction.
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.

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.
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:
- 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.
- 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.
- 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 features. 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:
- 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.
- 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.
- 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.
Leave the stump prepared in this way 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 also be destroyed so much that they cannot give young shoots.Figure 3. Chemical destruction with saltpeter
But when using saltpeter, it should be taken into account 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 has the advantage 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.
In addition, it is better to carry out the treatment in early spring or autumn, after harvesting, since the fruits of crops growing near the treated stump cannot be eaten after treatment.
How to get rid of stumps and tree roots on the site: 4 ways
Sooner or later, every owner of the site is faced with the problem of removing stumps. Even if they didn’t exist initially, they will definitely appear over time. Aging and diseases of fruit trees, the need for redevelopment of the territory - there can be a lot of reasons. We will analyze several working methods on how to remove a stump from the site quickly and easily.
All about uprooting stumps yourself
Is it always necessary
4 methods that work
— Manual uprooting
— Chemical destruction
The easiest way to solve the problem of removing large and small stumps is during the development of the site. If the territory has not yet been ennobled, special equipment is ordered. With its help, in just a few hours, they clean the site. The disadvantage of this method is obvious: heavy machinery and destructive mechanical uprooting will leave numerous marks on the site. But if the territory is still going to be ennobled, it's not scary.
It is much more difficult to choose the right solution, how to get rid of a stump in an already developed area. There can be a lot of options, but each of them has certain disadvantages. First of all, you need to understand whether it is really necessary to get rid of a piece of wood. After all, you can benefit from them. For example, an interesting landscape decor is obtained from the rest of the trunk. In order to make it, the core is hollowed out and a fertile substrate is poured into the cavity. The resulting "bed" is used to grow flowers, vegetables or berries. Such a flower bed or garden bed can become the center of an interesting multi-tiered composition. A good option is growing mushrooms. Their spores are inhabited by the remains of wood, where mushroom families germinate very quickly.
It turns out an unusual and useful “decoration”. Honey mushrooms or oyster mushrooms will give several harvests over the summer. At the same time, the mycelium actively destroys wood, because it needs food for growth. In five to six years, mushrooms will completely destroy the remains of the tree. Flowers or vegetables "work" in a similar way, however, they need much more time to destroy.
Making flower beds in the garden with your own hands: useful tips and photos that you will love
If the stump stands where it is planned to set up a flower garden or beds, or somehow interferes with the improvement, you have to think about how to uproot the stump on the site. You can invite specialists with a cutter. A powerful technique will crush the wood, deepening 20-30 cm. This is enough to get rid of the roots. Unfortunately, it is not always possible to use the services of specialists. Then use the methods available for independent use.
1. Manual uprooting
In order not to mess around with the remains of the tree, when felling, you can cut the trunk at ground level. This is done if they do not interfere and it is possible to leave them to rot in the soil. To speed up the process, the cut is chopped with an ax. Sooner or later, the rhizomes will rot, but this will not happen very soon. All the time, while the processes of overheating are going on, it will not be possible to break a garden bed, put up any building, etc. at this place.
When there is no time to wait, choose manual uprooting. This is a very labor intensive method. To begin with, they dig a hole around the hemp, exposing the rhizome. It is important to expose all root processes in the trunk area. You can not remove the soil with a shovel, but wash it off. To do this, put a drain chute in the pit and “wash” the rhizome with a stream of water under strong pressure. The bare root shoots are cut. This must be done very carefully so as not to get hurt. It is extremely inconvenient to work in the pit, the roots are most often mixed up and very hard. But it is imperative to cut them, otherwise, when the hemp is pulled out, the long rhizome will easily destroy the adjacent path, fence or building foundation. A snag with chopped roots is fixed to a winch or any other lifting mechanism and pulled out of the ground. If it is not possible to use mechanical devices, the stump is split, loosened and untwisted fragments, removed from the ground.
Uprooting takes a lot of time and effort, so not everyone is ready to do it. There are ways to remove the stump without uprooting. They are much easier. Let's analyze the most effective of them.

2. Use of fire
A very simple but rather dangerous method. It can be used with certain restrictions. First of all, the remains of the tree must be removed from buildings, fences, underground and air communications, power lines. It is impossible to carry out the procedure on peat soils (peat bogs ignite quickly and can smolder for a long time). Putting out an underground fire is very difficult, almost impossible.
Burning is carried out in calm, dry weather. All flammable items are removed to a safe distance and be sure to prepare a supply of water in case the situation gets out of control. Start by drilling two channels inside the hemp. Drill to the maximum possible depth. One is lowered strictly vertically, and the second is placed at an angle to it. In the first there will be a fire, through the second it will receive the air necessary for combustion. In large snags, it is advisable to drill several holes for air. This will speed up the burning.
A flammable liquid is poured into the central cavity. It is best to take lighter fluid or diesel fuel. Gasoline will burn very quickly, which will not give the desired effect. A cotton wick is lowered inside the hole and lit. The only thing left to do is keep the fire going. Depending on the condition of the wood, it will last from 13 to 16 hours.
You can speed up the process if you remove the stump using the Tsiolkovsky method. In this case, "caramel fuel" is used as fuel. This is a mixture of ammonium nitrate and sugar in a ratio of 7:3. The ingredients are mixed and carefully poured into the drilled hole. You need to know that the mixture gives a very strong flame. In a matter of minutes, the entire snag, including the roots, burns out. Therefore, it is imperative to observe precautionary measures: it is necessary to ignite the fuel from a certain distance; for this, a gasoline “path” is laid to it.

3. Chemical destruction
The essence of the method is the decomposition of root residues with the help of chemicals. This is an effective, but slow way to get rid of tree roots. Different preparations are used for destruction, but the method of their application is approximately the same. To begin with, as many deep holes as possible are drilled in the saw cut. This is best done in the fall, two to four weeks before the first frost. The chemical substance will have time to penetrate into the most remote root shoots before the cold weather and will destroy them all winter.
Chemical reagent is poured into the holes. Most often it is carbamide, aka urea. This is a well-known fertilizer that decomposes wood in large quantities. The granules are tightly packed in the cavity, spilled with water, covered with plastic cut and the film is securely fixed. You can plug filled holes with corks or cover with clay. After a few months, the snag will soften, it will be easier to remove it from the ground. Urea, even in large quantities, is relatively safe for the site.
The same cannot be said about potassium or sodium nitrate. They are also used to destroy wood residues. Nitrogen salts are toxic in high doses, so the technique is not suitable for areas where there are new plantings near tree residues. Saltpeters act differently than urea. They dry up the root, which is then easily taken out of the ground. If the soil is not peaty, you can simply burn it, because it is saturated with a substance that stimulates combustion. To destroy a hemp with a diameter of 15-16 cm, it is necessary to lay 2,000 g of any reagent.
Salt will help solve the problem of how to remove stumps from freshly cut trees. Tree juices will quickly spread it throughout the rhizome, which the salt will “dry out” in a year and a half. The removal procedure is the same as described above. You need to know that a high concentration of salt will not allow plants to develop in this place for several years.
Copper or iron sulphate can also be used as a chemical agent. Each of these preparations is a highly effective insecticide and fungicide, toxic in large doses. Vitriol is used for chemical uprooting of diseased stumps. No other way can prevent the infection of nearby plantings.
Herbicides work quickly and effectively. They process only a fresh cut, pour the roots with a solution. Autumn processing allows you to remove the rhizomes from the ground in the spring without any problems. But the soil turns out to be contaminated with herbicides, nothing will grow here for several years.
Cherry pruning: all the rules that a gardener needs to know
The essence of the technique is that the mulch layer blocks the access of air to the saw. Without oxygen, the roots slowly die. True, it takes a lot of time. Mulching is more suitable for destroying small stumps. For example, it will be a good solution for getting rid of cherry or plum roots.
The trunk is cut at ground level or slightly above. The saw cut is covered with a dense layer of mulch 20-25 cm high. It is desirable to cover the entire near-trunk circle. Any organic matter is suitable as mulch: chopped grass, leaves, plant debris. The rhizomes will rot for a long time, for several years. All this time, organic matter will have to be added, as its layer is thinning.
7 reasons to mulch your garden (if you still don't)
There are many ways to uproot trees. The optimal one is chosen taking into account the prevailing conditions. So, effective mechanical uprooting is not suitable for an already ennobled area, but on a newly developed area it will help to get rid of rhizomes quickly and easily. In order not to spoil the landscape design, they invite specialists with a cutter, they can remove any stumps in a short time. Or use the safest chemical uprooting. Burning is effective, but it must be done very carefully. The risk of fire and fire is too great.
