How do you grind a tree stump
Stump grinding and removal tips from tree experts
Many clients long to have a flat, well-manicured lawn, but if their yards have pesky stumps in the way, the aesthetic can be thrown off.
Take a look at a few tips tree experts recommend when removing a stump, as well as how to avoid some of the most commonly made mistakes during the process.Your preferred method
Stump grinding is the name of the game for Todd Burke, owner of Dave’s Tree Services in Egg Harbor, Wisconsin, as it’s one of the most commonly performed services in their area.
While there may be multiple methods for removing stumps, in his experience, Burke says the best way is by using equipment specifically designed for stump removal.
“You can fight with a lot of different methods, but an actual stump grinder is going to do the job best,” says Burke. “Heavy equipment will do the job, but it’s not the answer. You’re going to have a big mess that way. ”
For their crews, Burke says they have two different stumpers. A larger one is pulled behind their vehicle and is used on larger projects, and the other is self-propelled and used on smaller projects.
Burke says he’s seen people use chemicals to remove stumps and others that attempted burning the stumps out, but he says he’s personally never seen the best results come from these methods.
“Those are home remedies, I guess you could call it, that I don’t feel work very well,” says Burke. “And of course, you get homeowners that want to do it themselves and go down to the hardware store and rent a small handheld version of a stumper.”
If the stumps are small and are of the softwood variety, Burke says this can be an effective solution for homeowners who prefer to do their own stump removal, but if the stump is a hardwood variety or is larger, it won’t be as effective.
“I hear homeowners say all the time they’ll take care of the stump themselves, and I’ll make the comment, ‘Well, when that doesn’t work for you, feel free to give us a call back, and we’ll take care of it for you,’” says Burke. “Nine times out of 10, those people call us back. The other methods of stump removal just are not effective.”Before you hit the site
Before starting the process of stump grinding, Burke says ensuring operator safety is paramount. The number one way Burke says someone can get injured while grinding a stump is by not knowing what’s under the ground.
Burke says the first step in this type of project is to get in touch with the local utility department and to call the Diggers Hotline to ensure all underground lines are clearly marked.
“Before we ever grind the stump, we make sure that yard has flags put out or there are marks spraypainted on the ground where there would be any utilities like a water line, electrical line or a gas line,” says Burke. “Whether this stump is properly marked for any underground utilities or not is your number one safety factor.”
When Burke does the locates or e-locates, he requests they mark out 10 feet around any stump that’s getting ground out. Burke adds that it doesn’t cost the customer or contractor anything to get these things marked off.
Burke says you need to also make sure you have properly trained staff working with you on these projects. To ensure this, Burke says they have safety manuals and a safety chart in each of their vehicles, and they perform safety training on all the equipment before getting out in the field.
“You do not want to take another individual who is not used to that machine, just give them a two-second rundown on how it works and have them go and grind stumps,” says Burke. “You want an operator very familiar with the machine.”
Even if everything is carefully marked, Burke recommends always having a plan in place to deal with what might happen if a line is hit.
“There should be safety policies and procedures so all of your stumper operators are aware of what they should do in case of an emergency,” says Burke. “When it comes to a job, no matter what job you’re doing, I don’t think you can be too safe or too prepared. ”Photo: ShutterstockGetting started
Once on the jobsite, Burke says to set up a safety barricade around the stump to keep debris from flying back and hitting operators.
After the barricades are up and the proper personal protective equipment (PPE) is on, he recommends taking a pickaxe and going around the area of the stump to see if anything can be pulled up before grinding begins.
Burke says a popular reason among customers for why a stump needs to be removed is to help the look and layout of the yard. Stumps can get in the way of mowing and lawn maintenance, so removing them and filling in the hole can help restore the space to its former glory.
When grinding a stump, Burke says it’s important to make sure you grind deep enough that the whole mound is ground out, which includes the roots and any dirt that flares up to the stump.
Burke says in many cases, customers want a stump removed so they can use that space for other plants, and sometimes they want to replant a new tree in the area.
If this is the case, Burke recommends not planting a new tree in the exact spot where a stump was removed. Even when the process is done thoroughly and correctly, Burke says there’s always a chance that the stump was not ground deep enough to entirely remove old root remnants that could interfere with a new tree’s development. Instead, he recommends filling the hole in and planting new trees close to the area.
If operators aren’t comfortable grinding the stump located close to a marked line, Burke suggests opting out of grinding the stump with machinery. If that’s the case, Burke says you can take a chainsaw and flush it as close to the ground as you possible so it’s not as unsightly. Or, he says you can hand dig down next to the utility line and use a mechanical grinder if you feel confident you could remove the stump that way.
“Once you know that you are safe at that point to grind, then you can commence stump grinding, but then you be careful that you do not go deeper than what you hand dug,” says Burke. “Stumps can be ground when they’re close to utilities. You just have to use extreme caution.”
Once the project is complete, Burke says it’s best to immediately clear the site of all debris, as it will be much easier to clear while the chippings are light and fresh. Next, make sure the hole is completely cleared out and fill it in with fresh topsoil.
Burke says to then rake over the area and lightly pack it down. Lastly, he says to break up the top of the dirt a bit and sprinkle grass seeds on it to help encourage new growth in the area.
How to Remove a Stump Without a Grinder
After you hire a commercial tree service to remove a tree, they can also remove the remaining stumps for an extra fee. Or, you can hire a different company to come in and do this work. But if you have felled the tree yourself, the task of removing the stump is left up to you—and it can be as difficult as removing the tree itself. You can hire a firm to come in with a large mechanical grinder to churn the stump into sawdust, but this can be expensive. Commercial stump removal can cost as much as $800 for a large stump or one in a tricky location. You could also rent a stump grinder for $150 to $400 per day, but getting this tool on-site and using it safely is no easy feat. But there are several methods that you can use to do this work without contractor costs or large equipment.
Equipment / Tools
- Digging bar
- Bow saws
- Steel-toed work boots
- Work gloves
- Drill with large bit
- Chain saw
- Plastic tarp
- Drill and large bit
- High-nitrogen garden fertilizer or potassium-nitrate tree stump removal granules
- Garden mulch
- Stump Out chemical
Watch Now: How to Remove a Tree Stump Without a Grinder
When to Remove a Tree Stump
A tree stump can be removed at any time after the tree is felled, but manual removal is sometimes easier if the stump has aged and dried out somewhat. If you have the ability to let the stump remain in place for a full year or even two, the dried wood may be easier to cut out than when working on a new stump that is still green. Chemical removal, however, should begin immediately after you remove the tree.
Before Getting Started
A small- to medium-sized stump can be removed by good old-fashioned muscle work. But larger stumps can involve so much work that it's not practical—unless you can drag it out of the earth with a chain attached to the back of a pickup. For larger stumps, use the chemical method instead. A useful tool for manual removal is a mattock, which has a broad end for digging and a sharpened end for slicing. Everyone has favorite tools to use, though, and the more various digging and cutting tools you have on hand, the better. For larger stumps, you may want to enlist the aid of a helper or two to speed the work.
For those who are not up to the physical effort, or have a tree stump is too large to remove by hand, there is an easier—though much slower—method. All wood will eventually decay and rot away, and it is possible to speed up this process by keeping the stump moist and adding nitrogen in the form of a high-nitrogen fertilizer or potassium nitrate stump-removal granules. This is not an instant process—it can take a matter of months or even a year or so before a stump vanishes completely—but it is quite easy.
There is a tree stump removal product that comes in a powdered form, called "Stump-Out," which is designed to break down the wood fiber of stumps, leaving them porous. The porous wood then absorbs kerosene readily. After the porous wood is soaked with kerosene and ignited, it begins to burn away, and the fire soon becomes a low, smoldering flame. If the use of kerosene and flame is acceptable to you (and allowed in your community), this is another cheap and easy option to remove a tree stump.
Disposal of large tree stumps can be difficult. Contact your local waste disposal authorities for instructions on how and where to dispose of large garden waste items.
How to Remove a Tree Stump ManuallyThe Spruce / Ana Cadena
Dig Down Around the Stump
Dig around the stump with the mattock's broad end. Once you have loosened the dirt in this fashion, shovel it out of your way. Be prepared to clear away a lot of soil. The bigger the stump, the more earth you'll be moving. This is necessary to gain access to all the roots that need cutting.
When digging out a stump by hand, a hose or pressure washer can be helpful to wash away dirt to expose roots as you dig downward.The Spruce / Ana Cadena
Sever Visible Roots
Use the other end of the mattock to start chopping your way through the tree roots. A bow saw can also be used to sever the roots as you uncover them.
Expose the Tap Root
Dig and chop your way under the root ball to the taproot. For all but the smallest of trees, taproots will be imposing enough to require cutting with an ax or large bow saw. Clean excess dirt off the taproot with a wet rag before cutting.
Sever the Tap Root
Chop through the taproot with your ax or with a bow saw. Be careful that the area is clear of people, pets, and objects before you start swinging the ax. Aim the ax carefully so that it does not strike dirt (which would dull the blade). Always wear steel-toed boots when wielding an ax.
It's best not to use an ax unless you have been educated in handling one properly. If you're not confident, try to use a bow saw for all your cutting. It may require more digging to expose the roots, but it will be safer.
Extract the Stump
Pull the stump from the hole. This may require the use of ropes or chains, as well as the assistance of helpers or a vehicle to yank a large stump from the ground.
How to Remove a Tree Stump Chemically
Cut Stump to Ground Level
Use a chain saw or bow saw to cut the stump down as close to the ground as you can, without allowing the chain saw's teeth to strike the ground (this will dull your chain). Wear steel-toed boots for this part of the job.
Drill Holes and Add Chemical
Drill holes a few inches deep into the stump in numerous places, using the biggest, widest drill bit you have. The wider and deeper the holes, the better.
Fill these holes first with water, then with a fertilizer high in nitrogen or stump-remover granules.
Potassium nitrate is considered a hazardous substance, so use caution when applying potassium nitrate stump-removal granules.
Water and Cover the Stump
Soak the ground all around the stump. Cover the stump with a plastic tarp. The tarp will act as a barrier to help retain moisture in and around the stump. Moisture is a powerful ally to have on your side for this project.
Apply an organic mulch over the plastic tarp, and water it thoroughly. An organic mulch such as tree bark or hay will hold additional moisture, keeping the area even wetter. Wet mulch is also heavy, which will help weigh the tarp down so that it doesn't blow away. For additional weight, roll some heavy stones onto the tarp. The mulch also serves the purpose of hiding the tarp from public view.
Covered with mulch, the tree stump will be invisible as it begins to rot away. You can even cover the mulched area with various planted pots and container gardens.
Tend the Stump While It Decays
Over the coming weeks, periodically remove the mulch and tarp and apply more water and nitrogen to the stump, then cover it again. Some patience is required here, as it can still take quite some time for the stump to completely rot away. But it will be considerably faster than the decay process normally occurs in nature.
Remove the Pieces
After four to six weeks, the stump may become soft and spongy enough to begin breaking it apart with an ax. Whatever wood cannot be broken up and removed should be treated again with water and nitrogen. At some point, you can bury what remains and let it complete the decay process underground.
How to Remove a Stump by Burning
Drill Holes and Apply Chemical
Drill holes into the stump with a drill and a large bit. Apply Stump Out chemical granules, then fill the holes with water. Wait four to six weeks for the chemical to do its work.
The more porous the stump, the more kerosine will be absorbed and the longer it will burn.
Soak With Kerosene
Slowly pour kerosene over the stump, taking care not to allow the fluid to run off and pool on the ground. Take your time to allow the kerosene to soak in. Never use gasoline or motor oil to burn a stump—gasoline is dangerously explosive, and motor oil creates toxic smoke when burning.
Tend the Fire
Ignite the stump and observe it from a safe distance as it burns. Remember that the stump may continue to smolder underground for quite some time, so put up barricades to prevent people or animals from accidentally walking over the embers.
Check out local community ordinances regarding open burning before using this method. While it is generally allowed in rural areas, urban and suburban locations often do not allow open burning of stumps.
A Sample Contract for Professional Tree Removal
When to Call a Professional
No matter what method you use, a tree stump of any appreciable size involves quite a bit of hard manual labor and often the use of potentially dangerous tools or materials. If, after reviewing these various methods, you have concerns about safety or the physical fitness required to do the work, it is best to call a professional removal service, who will have the tools and personnel to do this work quickly and safely.
It's very common for a homeowner who removes a stump themselves to then resolve to never, ever, do it again. The cost of professional stump removal often seems like a bargain to anyone who has ever tried to do it themselves.
7 ways to remove the stump without uprooting.Photo, video
Sometimes you have to part with the trees on the site. There are enough reasons for this, maybe it got too big or stopped bearing fruit and got sick. Removing a tree from a site can be time-consuming and sometimes costly. But the most unpleasant thing is when, after cutting down a tree, your work has stalled on a stubborn stump. And all thoughts are only about how to remove this stupid stump!
The most interesting thing is that the extensive root system of the stump continues to give young shoots, and the stump itself continues to grow and not rot. And continues to live for a long time after the tree has been cut down. Luckily, there are a few tricks you can use to rid your yard of an annoyingly stubborn stump. So, how do you remove a stump without uprooting?
- Does the stump remover kill the grass?
- What can be put on a stump to make it rot?
- Will bleach kill the stump?
- What is the best way to kill stumps?
- How long does Epsom salt take to kill a stump?
Physical Stump Removal
If you need to remove the stump as soon as possible, you can deal with it quickly by digging, crushing or burning. Physical removal methods come with some problems. Let's take a closer look at each of these methods to find out if they are right for you or not.
Digging out the stump
For small stumps, up to about 30 cm in diameter, digging out may be the most practical solution. Digging requires only basic hand tools, not special equipment or renting a large and expensive machine. This is a time-consuming process, but it can be done with the right tools.
To dig a stump, you will need a sturdy shovel, a hoe and a metal bar. A narrow shovel with a medium-length handle that digs deep and easily maneuvers around a dense root base. The hoe cuts roots like an ax and easily loosens compacted soil. Use a twig to dig deep or narrow places and pull out stubborn roots.
To remove a stump, start by loosening the soil around it with a hoe. Clear loose soil with a shovel. When the roots are exposed, cut through them with a hoe or an axe. Continue working down and in from all sides to the main root under the stump. Use a twig to loosen the soil underneath the stump or pry the side of the stump for extra work space. When the taproot is exposed, use the sharp edge of a hoe to pierce it. Remove the stump with the root ball and any large roots.
Burn the stump
If the stump is completely dry, it can be burned out. This method may take longer than digging and does not completely remove roots below soil level, but may give satisfactory results with slightly less physical effort.
Before starting a fire, clear the area of flammable materials and dig up the ground within a radius of at least 5 meters from the stump. Also, run a garden hose connected to the water to quickly extinguish any flames that ignite outside the area of the burning stump. Finally, schedule time to be near the stump at all times while it burns. This can take quite a long time, depending on the size, type of wood, moisture content, weather conditions, and many other variables.
Now the hard part. Setting fire to a stump is not as easy as it seems. Dousing it with flammable liquid is not a good idea. It's dangerous and really not that effective. The liquid tends to burn without actually igniting the stump. Instead, build a fire at the top of the stump and keep it burning. To speed up the process, improve airflow by digging up the soil at the base of the stump. Fire needs oxygen, so the more it is exposed to it, the faster it will burn.
Grind the stump
Grind the stump can take anywhere from 15 minutes to 2 hours or more. You can hire someone to do this job, but it's an easy process to do on your own. Stump removal machines are available from equipment rental companies. If you are doing this yourself, be sure to wear appropriate safety gear when using the stump grinder, including safety goggles and hearing protection.
The process of crushing stumps can be hazardous to the operator and bystanders. The machine grinds to a depth of about 20 cm, throwing debris to the sides. The risks of using a stump grinder are associated with wood chips or stones flying in all directions.
Communications may be cut off. Before grinding the stump, find out if you have any communications - electricity, water or communication lines - so that you can avoid damaging them. Keep bystanders (and pets too) away from the work area while working.
Stump Destroyer at Home
If you have enough time, you can use household tools to destroy the stump. The natural processes of decay will weaken the wood, allowing you to remove it more easily. If the long and slow method suits you, consider using one of these simple and inexpensive home remedies that you may already have on hand.
An excellent option, he was awarded a separate article. Luckily, there is a favorite bath product that doubles as a simple stump remover: Epsom salts. Epsom salt or magnesium sulfate is a naturally occurring compound of magnesium, sulfur and oxygen, which are essential plant nutrients. But in high concentration, it draws moisture out of the stump, killing it within a month or more.
Start the destruction of the stump by drilling holes with a diameter of 80 to 130 mm, about 8 cm from the edge of the stump. Try to make them as deep as possible, spaced about 2-3 cm apart. When you have made enough (the more the better) holes in the stump, cover them with Epsom salts and add water. But not too much. It is needed only in order to soak the stump with a solution without spilling it out. Then sprinkle the entire top of the stump with Epsom salt. Then cover the stump with a thick film or tarp. Then rainwater will not wash the secret ingredient out of the holes. This process can take about a month or more, the solution will eventually cut off the moisture supply to the roots and they will dry out, allowing you to easily uproot the stump and get rid of it forever.
Rock salt is another versatile product that can help get rid of unwanted stumps, but caution is warranted here. Like Epsom salt, it kills by drawing vital moisture from the stump. Although rock salt is a natural substance that takes about the same time to break down as Epsom salt, it is less desirable.
Rock salt or sodium chloride contains the elements sodium and chlorine. These elements not only kill stumps, but also have an adverse effect on useful plants. If the salt concentration in the soil is too high, sodium and chloride replace the phosphorus and potassium needed by plants, causing deficiency and plant death. Look out for other home remedies that use salt water to kill poison ivy and other hard-to-kill weeds.
If you want a natural, additive-free approach to stump removal, try this option. Trees and shoots that grow on stumps need light for photosynthesis, so why not turn it off? To blackout a tree, you'll need a large tarp or sheet of black plastic and a large amount of organic waste, such as wood chips, fallen leaves, or grass clippings.
First cut the tree as close to the ground as possible. Then cover the stump and as many exposed roots as possible with a tarp. Finally, pile the organic waste on top of a tarp at least 30 cm thick. Shoots may develop from the exposed part of the root zone, but the stump will slowly weaken and die. The option is not fast, but covered and forgotten. After 3-5 months, the stump can be removed with a shovel.
Most chemicals are labeled "Use only as directed". We agree with this. Although there are a huge number of chemicals that can effectively destroy stumps, perhaps in the same way as Epsom salts. Many of them cause collateral damage to nearby plants, animals, or people. What is the point when there are better and safer alternatives? With that in mind, read on for a few well-known examples.
Many chemical products designed to remove stumps are made with potassium nitrate. This compound contains potassium, nitrogen and oxygen, which reduce the time of natural decay from several years to 4-6 weeks. This is environmentally friendly and is a fairly quick method.
Removers are most effective when used on old, dead stumps. If you are dealing with a freshly cut tree, start with a stump killer based on products containing systemic insecticides such as triclopyr to kill roots and prevent shoot regrowth. Apply the chemical to the top of the stump within a few minutes of making a fresh cut so that the product quickly soaks into the remaining stump and roots. If the stump was cut off not so long ago, but not 10 minutes ago, then you can drill holes as in the version with salt.
DO NOT use bleach
Bleach is not sold as a herbicide and should not be used on plants. The dangers outweigh the minor benefits. As noted earlier in the rock salt segment, chlorine is indeed a naturally occurring element, but it creates problems for desired plants when concentrated in the soil. The truth is that applying the high concentration needed to kill a stump can expose adjacent grass, shrubs, and perennials to toxic levels of chlorine and greatly increase soil pH. Instead, save the bleach for more appropriate uses.
DO NOT use motor oil
There is no good reason to use motor stump oil instead of one of the above products. Plus, a liter of motor oil costs about the same as a stump killer, which is a tried and tested product for just that purpose.
DO NOT use diesel fuel
Diesel is popular as a stump burning base because it does not explode like gasoline. However, as noted, the addition of a flammable liquid to the process will not provide the sustained, sustained combustion required to eliminate the stump. As a chemical stump killer, it will likely have an effect too. But judge for yourself, you need to buy a canister and some diesel fuel. Perhaps instead it makes sense to purchase specialized solutions or Epsom salts?
Frequently asked questions about how to kill the stump
Does the stump remover kill the grass?
Stump remover pellets, made from potassium nitrate, specifically designed to kill stumps, will not kill grass. In fact, they are made up of compounds that break down into plant-friendly nutrients.
What can be put on a stump to make it rot?
Mushrooms are the most efficient organisms for breaking down wood fiber, so you can plant fungal spores in a stump. An old method of speeding up the decomposition of a stump is to cut grooves in the stump, sprinkle earth on top, and cover the stump with a tarp to promote microbial growth.
Will bleach kill the stump?
No studies have shown that bleach is an effective stump killer.
What is the best way to kill stumps?
The best stump killer is a systemic stump killer herbicide, such as triclopyr, applied directly to the fresh cut of the stump.
How long does Epsom salt take to kill a stump?
The Epsom Salt Method requires 8 to 10 weeks to kill the stump as directed above.
If left to rot naturally, a large stump can take decades to die and decompose. Meanwhile, it can cause many difficulties, from unsightly appearance to walking obstacle hazards and more. To get rid of the problem, you have several reasonable and effective options. For complete removal, when all the big roots should be gone, grab your tools and dig out the stump. Shredding stumps is a quick and easy solution for large stumps, but the bottom of the taproot will be left to rot naturally.
Chemical stump removal is cheaper and requires less time and effort. But be careful to avoid unproven and unnecessarily risky household chemicals. Choose Epsom salts to kill stumps in the bud and make later removal easier. If removal is necessary but not urgent, apply stump remover pellets to speed up the process of breaking down already dead stumps. These products work slowly, but greatly facilitate the laborious process of destroying stumps on the site.

We remove the stump in different ways.
A stump in a garden plot not only takes up free space, but new trees can also grow from it. In addition, it can be a refuge for various insect pests. Therefore, many gardeners seek to remove stumps from their plots.
Exists several ways to remove stumps. Each of these methods has its own Advantages and disadvantages.Removal of a stump using machinery.
The easiest way is to uproot the stump with the help of special vehicles. This method is quite simple and effective, but it has one significant drawback - this is the high cost of work. For this reason, for an ordinary summer resident, this method will be unacceptable.
Therefore, we will analyze in detail other ways to remove stumps.
1 Removing the stump by digging around.
2 Stump removal with saltpeter.
3 Use of urea or salt.
4 Stump removal with mushrooms.
5 Stump burning.
Removing the stump by digging around. The stump is dug around to expose its roots.
This method can be applied to small stumps that need to be removed as soon as possible.
To do this, a hole is dug around the stump with the aim expose its roots. Then, with the help of an ax, a saw and a crowbar, all the roots are broken off. and the stump is removed.
The disadvantage of this method is that the roots remain in the ground and if it is planned to plow the ground at this place, then the remaining roots will interfere.
Stump removal with saltpeter.
This the method is suitable for those cases when the stump is quite large and it is not required uproot quickly.
Essence This method consists in impregnating the stump and its roots with saltpeter. AT as a result, the stump dries up. After the stump dries, it can be overlaid branches and set on fire. A stump soaked in saltpeter burns quite well. Because saltpeter is a strong oxidizing agent, then combustion occurs without access to air and therefore the roots soaked in saltpeter also burn out.
This method cannot be used if the soil under the stump is peaty. There is a risk of peat fire, an underground fire.
For the process of impregnation of the stump and its roots with saltpeter go from six months to 1.5 years.
If the stump is fresh, then it is better to saturate it with saltpeter in the fall. At this time, there is no juice movement, so saltpeter can quickly penetrate into root system.
Two types of saltpeter can be found on sale - potassium nitrate (potassium nitrate) and ammonium nitrate (ammonium nitrate).
"Potassium nitrate ( potassium nitrate ) is used in the manufacture of black powder and some other combustible mixtures (for example, caramel rocket fuel), which are now almost completely used in the production of pyrotechnic products. " - Wikipedia
"Ammonium nitrate (ammonium nitrate) - Most of the ammonium nitrate is used either directly as a good nitrogen fertilizer, or as an intermediate to obtain other fertilizers. To prevent the creation of explosives based on ammonium nitrate, commercially available fertilizers are supplemented with components that reduce the explosion and detonation properties of pure ammonium nitrate, such as chalk (calcium carbonate)." — Wikipedia
Since ammonium nitrate is diluted with chalk, to reduce its explosiveness, it is better to use potassium nitrate.
So, to use this method, you need to drill holes in the stump. For this purpose, it is convenient to use a pen drill for wood. The more holes, the better, since more saltpeter can be poured into the stump. For one stump with a diameter of up to 15 cm, approximately 2 kg of saltpeter is consumed.We drill holes in the stump.
Now pour potassium nitrate into these holes. Since saltpeter is very soluble in water, you can still pour a little water into the holes so that the wood of the stump absorbs it along with saltpeter.Pour potassium nitrate into the holes.
After stump should be covered with some kind of polyethylene and its edges sprinkled with earth to atmospheric precipitation did not contribute to the leaching of saltpeter from the stump. Instead of covering polyethylene can be hammered into the holes with wooden plugs.
It remains to wait the necessary time and then burn the stump along with the roots.
Use of urea or salt.
Essence method is to impregnate the stump with substances that contribute to its accelerated decay. After the stump turns into dust, it can be easily uprooted with ordinary scrap or simply broken with his sledgehammer or axe.
This The method is also quite time consuming. It will take time for the stump to rot at about 1-1.5 years.
B common salt (sodium chloride), urea are used as active substances (carbamide) or potash (potassium carbonate).
Required understand what salt causes local (surface) soil salinization. And later in this place is unlikely whether any plant will grow.
To apply this method, you need to follow all the steps as when impregnating a stump with saltpeter. That is, you need to drill holes in the stump, then pour the active substance into them, pour a little water and cover with polyethylene.
Stump removal with mushrooms.
This is another way turn the stump into dust. To do this, you need oyster mushrooms or mushrooms.
Mushroom caps needed chop, add water and shake well. This solution is then filtered and water the stump. To increase the area of \u200b\u200bwetting, you can make a notch with an ax in the stump To maintain constant humidity, the stump must be covered with branches. Desirable moisten the stump occasionally, especially in hot weather. After a few months, the mycelium should germinate.
An average stump will produce a crop of mushrooms up to about 6 years, then the stump will turn into dust. The remains of the stump can then be easily broken.
The best time to infect a stump with fungal spores is from May to August.Honey mushrooms grow on an old stump.
Stump burning .
This a fairly quick way to remove a stump. Unlike soaking the stump with saltpeter, this method does not require much time and leaves intact roots from the stump to earth. To avoid an underground fire, this method cannot be used on peat soils.
Burn stump can be done in two ways.
- install a metal barrel without a bottom. In this barrel, you need to periodically burn garbage and over time the stump will burn out completely. This method is best suited for a fresh, recently sawn stump.
- Can be from a stump make the so-called Finnish candle. This method is suitable for dry stumps. Fresh stumps will often go out.
First, a hole is drilled in the center of the stump. The hole diameter should not be too small. A diameter of 20mm is best.
