How to kill a gum tree quickly

How to Kill a Eucalyptus Tree | Home Guides

By SF Gate Contributor Updated September 24, 2021

Native to Australia, Eucalyptus trees (Eucalyptus globulus) have become an invasive species in the United States, including the state of California, says the California Invasive Plant Council. These trees grow in thick groves that crowd out native plants, resulting in a loss of biological diversity. One of the best ways to control the spread of this invasive species is to kill the tree by drilling into the trunk or frilling the bark before applying an herbicide.

  1. 1.

    Mix up a batch of glyphosate or triclopyr herbicide at a 50 percent concentration by following the instructions included with the herbicide, advises the University of Florida IFAS Extension.

  2. 2.

    Pour some of the herbicide solution into a handheld spray bottle and set it aside so it is ready to use as soon as you finish preparing the tree trunk.

  3. 3.

    Drill holes into the trunk of the eucalyptus tree at a downward 45-degree angle using a 5/16-inch flat spade drill bit and a power drill. Space the holes about 3 inches apart around the circumference of the trunk. Each hole should be at least 2 inches deep so it cuts into the cambium, the inner tissue of the tree.

  4. 4.

    Set the handheld spray bottle to the squirt setting and use it to fill the holes you just drilled with the herbicide solution.

  5. 5.

    Allow several weeks for the herbicide solution to soak into the cambium of the eucalyptus tree. During the warm spring and summer months, it should take between two and four weeks for the tree to die.

  6. 6.

    Cut two parallel grooves around the circumference of the eucalyptus tree to a depth of at least 1 inch using a chainsaw. This tree-killing method is called girdling.

  7. 7.

    Spray the herbicide solution into the grooves, or girdles, in the trunk, wetting the exposed cambium completely. If you prefer not to use herbicide to kill the tree, use a chainsaw or hatchet to remove the bark between the two girdles.

  8. 8.

    Make a series of downward-angled cuts all the way around the circumference of the eucalyptus tree trunk with a hatchet, leaving the cut pieces of bark attached. This method is called frilling, and it is best applied to trees more than 4 inches in diameter.

  9. 9.

    Spray the herbicide mixture into the cuts, or frills, until the cambium is thoroughly wet. Depending on the diameter of the tree, this method can take several weeks to kill the tree.

  10. 10.

    Cut down the dead tree using a chainsaw and dispose of the trunk as desired.

  11. 11.

    Grind the remaining stump down to ground level using a stump grinder.

  12. 12.

    Apply a commercial stump remover to the eucalyptus stump by following the manufacturer's instructions. Killing the stump is an essential step in killing a eucalyptus tree because, like many trees, eucalyptus can sprout from the trunk and create new plants.

    Things You Will Need
    • Glyphosate or triclopyr herbicide

    • Handheld spray bottle

    • 5/16-inch flat spade drill bit

    • Power drill

    • Chainsaw

    • Hatchet

    • Stump grinder

    • Stump remover


    If you are using the drilling method to kill eucalyptus trees during the winter, space the holes in the trunk only 1 inch apart. Depending on the temperature, the tree may be dormant in the winter and a greater quantity of herbicide will be necessary to kill it.


    Always wear protective gear and exercise caution when operating power tools like the power drill and chainsaw.

If you can, drill a few holes in the roots or at the base of the tree. Take boiled hot water that you've added a whole box of salt to and pour into the holes. If you can't drill holes then pour hot salt boiling water around on top of the roots and around the tree. This does take alittle time to do. but by later in the season it should rot. You can also use this method on stumps that you want to get rid of. It rots them completely. Hope this helps you.

A tree removal service can remove even the tallest sweet gum trees by climbing the tree and lopping it off from the top down. The problem with killing the tree as it stands is that then the tree will fall when the next big wind blows -- probably onto your house, car, or propane tank, luck being what it is.

Question: Sweet Gum Tree Root Removal?

October 10, 2011

I just had a sweet gum cut down. It was very close to my home. I still have the root to get rid of. The bad part is some of it is under my home so we can't use a grinder. What is the fastest way to kill and remove this stump and roots?

I've heard of success by driving a huge nail or railroad spike down the center of the stump, but it takes years to accomplish the subsequent rot of the stump and root.


There are products available at plant nursery centres that hasten the decomposition, make sure you read and follow the directions carefully.

Grind the stump down as much as possible, then go to the hardware store and and buy a container of roundup for trees and bushes. Pour the roundup liberally over the remaining underground stump. The roundup will kill stump roots so no new shoots are sent up.

Over time, the roots will rot in the ground. If some shoots are sent up, make sure you spray them too. If you want, you can also buy something called "root rot" at the hardware store also. It will help the stump to deteriorate quicker.

Do NOT ever use Roundup. (This stuff has been banned in Europe for years as a cancer causing agent.) The Sweet Gum tree's roots form a wide network and the Roundup with get into the ground (and groundwater) and destroy other trees and plants as well. After the tree is down, severing a couple of the main roots will destroy what is left and make them easier to remove with equipment.

This is Oh, so totally wrong. To kill a gum tree quickly and effectively: drill three or four holes around the bottom of the tree with the 1/4 in. bit; drill at an angle pointing down towards the ground. Then carefully pour straight Roundup (18% concentration or higher) to fill the holes--you're done.


The tree will be dead in 2-3 months and it'll start showing because the leaves will turn brown and start falling. The tree is pulling water and nutrients from the ground upwards to feed itself and sustain growth--it will pull the Round Up up and it will NOT go into the ground.

Round up has been given a bad name. People who say that round up caused their cancer did not use the product well. Wear protective gloves, mask, clothing, glasses. Don't ever spray any type of herbicide into the wind.

I don't think that will be enough. Plus it's not very safe, as you want to guide where the tree falls. Depending on the size, you might consider calling a tree service.

I own a tree service so I have seen some pretty reckless attempts at tree felling but that would take the cake. You would have no control of the tree if and when it falls.

I have taken dozens of trees down by digging around the base and pushing it over with a small excavator. I can control the direction of the falk and get the stump out all in one shot.


I have taken down pine trees as big as 16".

The easiest way to kill a sweetgum (that is clear of anything it can damage) is to "ring" the bark about 2 to 3 inches around the base. Remove bark down to the bare wood and coat with an herbicide. In two to three months the tree will be dead. THEN cut down. Wood will be easier to cut and handle than green wood. If desired wait longer and pick up parts as they fall. The tops usually fall first and then it is easier to finally fall the "log" part.

Myths and misconceptions

Last updated: November 23, 2020

FACT: Vitamin and mineral supplements do not cure COVID-19

Micronutrients such as vitamin D, vitamin C and zinc are essential for normal functioning immune system and are vital for maintaining health and nutritional well-being. At this time, there are no recommendations regarding the use of micronutrient supplements for the treatment of COVID-19.

WHO is coordinating efforts to develop and evaluate medicines for the treatment of COVID-19.

FACT: studies show no clinical benefit of hydroxychloroquine in the treatment of COVID-19

Hydroxychloroquine or chloroquine, a drug for the treatment of malaria, lupus erythematosus and rheumatoid arthritis, is under investigation as a potential treatment for COVID-19 19. To date, this drug does not reduce mortality among those hospitalized with COVID-19.patients and does not help patients with moderate disease*. Hydroxychloroquine and chloroquine are considered safe for the treatment of most patients with malaria and autoimmune diseases, but off-label use without medical supervision can cause serious side effects and is not recommended.

*Additional studies are needed to evaluate the clinical value of this drug in mild cases of COVID-19 or as a pre-exposure or post-exposure prophylaxis for coronavirus infection.

Is dexamethasone indicated for all patients with COVID-19?

Dexamethasone should only be given to patients in whom it is vital. Dexamethasone reserves should not be formed.

The administration of dexamethasone to patients with mild symptoms of the disease does not give a positive effect. Dexamethasone is a corticosteroid with anti-inflammatory and immunosuppressive effects. In some patients on mechanical ventilation, the appointment of dexamethasone at a daily dose of 6 mg for 10 days leads to an improvement in the condition.

Can I wear a mask while exercising?

DO NOT wear a mask while exercising as it may interfere with comfortable breathing.

Sweating can cause the mask to become wet faster, making breathing difficult and promoting microbial growth.

An important preventive measure during exercise is to maintain a distance of at least one meter from others.

FACT: The virus that causes COVID-19 is not transmitted through water or swimming

The virus that causes COVID-19 cannot be transmitted through water through swimming. However, the virus is spread through close contact between people.


Avoid crowded places and maintain a distance of at least 1 meter from others, even while swimming or in pool areas. When out of the water, wear a mask if physical distancing is not possible. Wash your hands frequently, cover your mouth and nose with a disposable tissue or your elbow when you sneeze or cough, and stay home if you feel unwell.

Can the virus be transmitted through shoes?

The likelihood of transferring the virus that causes COVID-19 on shoes and catching the virus through shoes is extremely low. As a precaution, particularly in families with infants or young children who crawl or play on the floor, it is recommended to take off your shoes and leave them at the entrance. This will prevent the child from coming into contact with various types of dirt present on the soles of the shoes.

FACT: COVID-19 is caused by a virus.

NOT a bacterium.

COVID-19 is caused by a virus from the coronavirus family. Antibiotics do not work on viruses.

In some patients with COVID-19, a bacterial co-infection may be a complication. In this case, doctors may prescribe antibiotics.

There are currently no registered medicines for the treatment of COVID-19. If you have characteristic symptoms, call your doctor or hotline and follow the instructions.

FACT: Prolonged wearing of medical masks*, if used correctly, DOES NOT lead to carbon dioxide intoxication or oxygen deficiency

Prolonged wearing of a medical mask may cause discomfort. However, it does not lead to carbon dioxide intoxication or oxygen deficiency. It is necessary to ensure that the mask fits the size and fits snugly enough to the face, allowing you to breathe normally. Disposable masks should not be reused and should be changed as soon as they become damp.

* Medical (surgical) masks are flat or pleated masks that are fixed to the head with ties or ear loops.

FACT: Most people who get COVID-19 recover

Most people who get COVID-19 experience mild to moderate symptoms and are able to recover with supportive care. If you have a cough, fever, and difficulty breathing, you should seek medical attention as soon as possible by first calling the health facility by phone. Never hesitate to seek medical attention if you have a fever if you live in an area where malaria or dengue is common.

FACT: Drinking alcohol does not protect against COVID-19 and can be dangerous

Frequent or excessive drinking increases the risk of health problems.

FACT: Thermal imaging thermometers DO NOT detect COVID-19

Thermal imaging thermometers can effectively detect the presence of fever (i.e. body temperature above normal). They do not determine if a person is infected with COVID-19.

The causes of fever are numerous. You can get advice over the phone from your healthcare provider, but if you live in an area with malaria or dengue and you have a fever, you should seek immediate medical attention.

FACT: Adding pepper to soup or other dishes DOES NOT protect or cure COVID‑19

Spicy pepper in food certainly has gastronomic benefits, but does not prevent or cure COVID‑19. The best way to protect against the new coronavirus infection is to maintain a distance of at least one meter from others, and frequent and thorough hand washing. In addition, a balanced diet, sufficient fluid intake, regular exercise and healthy sleep have a favorable general strengthening effect.

FACT: house flies DO NOT transmit COVID-19

There is currently no evidence or information to indicate that house flies can transmit the viral agent COVID 19. The virus that causes COVID 19 is spread primarily through aerosol droplets that form when a sick person coughs, sneezes or talks. In addition, infection is possible in case of contact with contaminated surfaces, if a person then touches the eyes, nose or mouth without washing their hands. To protect yourself from infection, you must maintain a distance of at least one meter from others and regularly disinfect surfaces that people regularly touch. Wash your hands regularly and thoroughly, and avoid touching your eyes, mouth, or nose.

FACT: Inhaling fumes or injecting bleach or other disinfectants DOES NOT PROTECT against COVID-19 and may be hazardous

Under no circumstances should you inhale fumes or otherwise inject bleach or other disinfectants into your body. These substances are capable of causing poisoning if ingested, and also cause irritation and damage. skin and eyes. Bleaches and disinfectants should only be used with caution to disinfect surfaces. Keep chlorine solutions (bleach) and other disinfectants out of the reach of children.

FACT: Using methanol, ethanol or bleach is NOT a way to prevent or treat COVID-19 and can be a serious risk

Methanol, ethanol and bleach are poisons. Their ingestion can lead to persistent health problems and death. In some cases, methanol, ethanol or bleach is added to the composition of cleaning products, which allows you to destroy viruses on the treated surfaces, however, these products should not be taken orally. The tool will not destroy the virus in the body and cause harm to internal organs.

To protect yourself from COVID‑19, you should disinfect your environment and various surfaces, especially those that you regularly touch. For such treatment, the use of diluted bleach or alcohol is allowed. Wash your hands regularly and thoroughly, and avoid touching your eyes, mouth, or nose.

FACT: 5G mobile networks DO NOT CONTRIBUTE to the spread of COVID-19

Viruses are not carried by radio or mobile phone waves. COVID-19 epidemicis spreading in many countries where 5G networks are not deployed.

COVID-19 is transmitted by airborne droplets, i.e. when drops released from the respiratory tract of a sick person enter the respiratory tract of a healthy person, for example, when coughing, sneezing, or when communicating. You can also become infected by touching a contaminated surface, and then to the eyes, mouth or nose.

FACT: Exposure to the sun or temperatures above 25

o C DOES NOT prevent coronavirus disease (COVID-19))

You can get COVID-19 no matter how sunny or hot the weather is. Hot countries are also reporting cases of COVID-19. To protect yourself, wash your hands frequently and thoroughly and avoid touching your eyes. mouth and nose.

FACT: coronavirus disease (COVID-19) is a curable disease. Infection new coronavirus infection MEANS that a person becomes lifelong carrier of the virus.

Most people who get COVID-19 can recover and the virus can be cleared from the body. If infected, symptoms must be treated. If you have a cough, fever and difficulty breathing, you should immediately contact for medical care, starting with contacting a medical facility by phone. With supportive care, many patients recover.

FACT: Being able to hold your breath for 10 seconds or more without causing coughing or discomfort DOES NOT mean that you are free from coronavirus (COVID-19)) or other lung disease

The most common symptoms of COVID-19 are dry cough, fatigue and fever. Some people get COVID-19 in a more severe form, such as pneumonia. The most accurate way to confirm infection with the virus that causes COVID-19 is through a laboratory test. It is impossible to confirm the infection with the above breathing exercise, which can lead to dangerous consequences.

FACT: COVID-19 transmissionmay occur in hot, humid areas

Current evidence indicates that transmission of the COVID-19 virus can occur in ANY AREAS, including areas with hot, humid climates. If a If you live in or travel to an area with reported cases of COVID-19, take protective measures regardless of climate conditions. Regular handwashing is the best way to protect yourself from COVID‑19. This measure eliminates possible viral contamination of hands and avoid infection if you touch your eyes, mouth or nose.

FACT: being outdoors in cold and snowy weather WILL NOT help kill the new coronavirus.

Therefore, there is no reason to believe that being outside in cold weather helps fight the new coronavirus infection or other diseases. The most effective way to prevent novel coronavirus infection (2019-nCoV) is to regularly clean your hands with alcohol-based hand rub or wash them with soap and water.

FACT: Taking a hot bath will not help against the new coronavirus infection

Taking a hot bath will not prevent you from contracting COVID-19. Normal body temperature is between 36.5°C and 37°C, regardless of the temperature of the water in the bath or shower. On the contrary, taking too hot a bath can be harmful and cause burns. The best way to protect yourself from COVID-19 is to wash your hands frequently. This will destroy viruses that may be on the skin and avoid infection if you touch your eyes, mouth or nose.

FACT: Novel coronavirus is NOT TRANSMISSIBLE through mosquito bites as a result of inhalation of droplets released from the respiratory tract of the patient, for example, when coughing or sneezing, as well as droplets of saliva or discharge from the nose.

At the moment, there is no information on the possibility of transmission of the 2019-nCoV virus through mosquito bites. To protect yourself from infection, keep your distance from people who have a cough or fever, and practice good hand and respiratory hygiene.

Is it true that electric hand dryers kill the 2019-nCoV virus?

No. Hand dryers do not kill the 2019-nCoV virus. To prevent a new coronavirus infection, you should regularly clean your hands with an alcohol-based hand rub or wash them with soap and water. Washed hands should be thoroughly dried with paper towels or an electric dryer.

FACT: Ultraviolet (UV) lamps should not be used to disinfect hands or skin on other areas of the body

UV radiation can irritate the skin and cause damage to the eyes. The most effective ways to remove viral particles are to use alcohol-based hand rubs and wash your hands with soap and water.

Do vaccines against pneumonia protect against the new coronavirus?

Pneumonia vaccines, such as pneumococcal vaccine or Haemophilus influenzae type B vaccine (Hib vaccine), do not protect against the new coronavirus.

This virus is fundamentally different from all others and requires a special vaccine. Scientists are currently trying to develop a vaccine against the 2019-nCoV virus, and WHO is helping them.

Although these vaccines are not effective against 2019-nCoV, vaccination against other respiratory diseases is still highly recommended.

Can regularly rinsing the nose with saline help protect against infection with the new coronavirus?

No. There is no scientific evidence that regularly rinsing your nose with saline helps protect against a new coronavirus infection.

According to some reports, regularly rinsing the nose with saline can speed up recovery from the common cold. However, there is no evidence that regular nasal lavage is effective in preventing respiratory infections.

Does garlic protect against infection with the new coronavirus?

Garlic is a health food with certain antimicrobial properties. However, during the current outbreak, there has been no evidence that garlic is effective in preventing infection with the novel coronavirus.

Is it true that only the elderly can get the new coronavirus, or are young people also susceptible to this infection?

The novel coronavirus (2019-‎nCoV) can affect people of all ages. Older people and people with certain medical conditions (eg, asthma, diabetes, heart disease) appear to be at increased risk of developing severe forms of coronavirus infection.

WHO recommends that people of all ages take measures to protect themselves from infection, such as through hand hygiene and cough hygiene.

Are antibiotics effective in preventing and treating novel coronavirus infection?

No, antibiotics do not work against viruses. They only treat bacterial infections.
The novel coronavirus (2019-nCoV) is a virus and therefore antibiotics should not be used to prevent or treat coronavirus infection.

However, patients hospitalized with 2019-nCoV infection may be given antibiotics to treat co-existing bacterial infections.

Folk remedies for ticks: skin treatment

In most regions of Russia, the summer season is already in full swing. By an unfortunate coincidence, May work in gardens and orchards coincides with the period of awakening of ticks. In the first weeks they are very active, hungry and aggressive. You can protect yourself from parasites with the help of special pharmaceutical products or home mixtures, which also effectively repel ticks - and some even kill them.

All anti-mites formulas are based on essential oils, water or alcohol. But which flavors to choose? In our selection - the five most effective, from which ticks try to stay away. All products are relatively safe for people, children and animals - provided there is no allergic or individual reaction to the components. Adults are advised to apply them to exposed skin, clothes and shoes. For protection, children are put on bracelets or ribbons with a few drops of fragrant oil.

Do not self-medicate! In our articles, we collect the latest scientific data and the opinions of authoritative health experts. But remember: only a doctor can diagnose and prescribe treatment.


Vanilla has a pleasant aroma - for us humans, but mites cannot stand its smell. You can protect yourself from parasites with the help of sweet vanilla water, which is prepared in a matter of seconds. Add a pinch of vanillin to a liter of water, put the composition on fire and bring to a boil. After that, you can wipe the exposed areas of the skin with vanilla water using a cotton pad.

The agent works no longer than two hours, so if you stay in nature for a long time, the procedure will have to be repeated.

If well tolerated, vanilla tincture can also be used to protect against ticks (outwardly, of course!) You need to prepare it in advance. To do this, in a dark glass container, you need to mix 100 ml of alcohol and several grams of vanillin. Leave the tincture in a cool place away from sunlight for a week. The finished solution can be used to process shoes and leather.

Lemon eucalyptus

Recently biologist and entomologist Roman Khryapin revealed interesting properties of lemon eucalyptus essential oil. As he told in an interview with Moscow 24, this agent is included in many industrial sprays against insects and is especially effective against ixodid ticks. A solution with lemon eucalyptus oil can also be prepared at home. It cannot be used in its pure form, since in high concentration all essential oils cause irritation and redness of the skin. As a base, you can use ethyl alcohol, diluted in half with water, and then diluted with a few drops of oil.

According to Khryapin, lemon eucalyptus oil is the only oil that can kill a tick if it crawls over treated leather or impregnated fabric.

An ant is not a friend to a tick!

It turns out that mites categorically do not tolerate the smell of formic alcohol. And if you tolerate it well enough, then you can protect yourself and loved ones by spraying their clothes and shoes before a walk. But not in its purest form! Formic alcohol is diluted with water in a ratio of 1: 1 (for example, 100 ml of alcohol and 100 ml of water). The agent works for about three hours, so when you go to nature, do not forget to take a sprayer with you.

Good old "Asterisk"

Keep the famous Vietnamese ointment for all diseases at home? The "asterisk" will also come in handy in the fight against ticks. Protective repellent is prepared as follows:

  1. Dissolve the "Asterisk" (a small amount on the tip of a knife) in 200 ml of warm water.
  2. Add a few drops of liquid soap and 1 tsp. apple cider vinegar.
  3. Shake container to mix all ingredients. Tool is ready!

Apply to exposed skin before walking. Before the first use, be sure to check the product on the back of your hand for an allergic reaction.


Ticks, like many other living creatures on the planet, do not like the smell of valerian. It is known that insects do not appear on the medicinal plant itself and generally prefer to stay away from plantings. A remedy based on valerian is prepared very quickly.
