Stinkhorn mushrooms are known for their unpleasant smell, likened to that of faeces, rotting meat, or a decaying animal. While they are not poisonous to humans or pets, their odour can be off-putting. These mushrooms grow on rotting organic matter and are often found in mulched areas or lawns, especially during cool and wet weather. If you are facing an invasion of stinkhorn mushrooms in your lawn and want to get rid of them, there are a few methods you can try, such as uprooting the mushrooms, using bleach or lime, or changing the pH of the soil. However, it is important to note that stinkhorn mushrooms are usually short-lived and will naturally disappear, and they may even provide benefits to your soil by breaking down organic matter.

What You'll Learn
Uproot the mushrooms
Stinkhorn mushrooms are a smelly reddish-orange fungus that can be identified by their putrid odour, likened to that of faeces or a dead and decaying animal. They are often found in moist, mulch-covered terrain. While they are not harmful to plants or pets, many people find them offensive and want to get rid of them.
Uprooting stinkhorn mushrooms is one way to kill them, but it is important to note that they are nearly impossible to kill and may come back even after aggressive attempts. To uproot the mushrooms, you will need to dig beneath the mushroom until you scoop out the egg-shaped base. Put on a pair of disposable gloves to avoid getting your hands dirty and smelly. Dig up the top layer of soil in about a 6-inch radius around the mushroom to ensure you remove any spores or undeveloped mushrooms. Place the excavated soil and the mushroom in a plastic bag, seal it shut, and put it out for trash collection. Do not discard the fungal matter with yard waste, as this could allow spores to escape and create new mushrooms.
It is important to note that simply removing the visible growth of the mushroom will not get rid of the fungus, as the majority of its body is left behind. Stinkhorn mushrooms have an extensive underground rooting system called mycelia, which can grow up to half a mile per day. Therefore, it is crucial to remove the entire specimen, including the egg-shaped base, to effectively uproot the mushroom.
Additionally, consider addressing the conditions that led to the growth of the stinkhorn mushrooms in the first place. Stinkhorn mushrooms thrive in moist, humid, and shady environments with abundant organic waste material. Remove any underground stumps, dead roots, and sawdust, as well as decomposing hardwood mulch, and replace them with pine needles, straw, or chopped leaves. Ensure that your lawn has good drainage and limit the availability of organic waste material to discourage the growth of stinkhorn mushrooms.

Kill with bleach or lime
Stinkhorn mushrooms are known for their unpleasant smell, likened to that of feces or rotting meat. While they are not harmful to humans or pets, many people find them offensive and want to get rid of them.
One way to kill stinkhorn mushrooms is by using bleach or lime. Here is a step-by-step guide:
Prepare the Solution
Start by mixing equal parts boiling water and bleach in a large bucket. It is important to do this in a well-ventilated area or outdoors. The water must be boiling hot as you mix it with the bleach.
Apply the Solution
Once you have prepared the solution, pour it directly onto the stinkhorn mushrooms. Make sure to do this while the water is still hot. The combination of hot water and bleach should kill the mushrooms and prevent new ones from growing.
If you want to be more precise, you can first dig up the mushrooms and then pour the hot bleach solution over the entire area where the stinkhorns were growing. This will ensure that any remaining spores are killed.
Using Lime
If you want to avoid using bleach, you can try using lime. Sprinkle lime powder over the mushrooms and the surrounding soil. Lime will make the soil uninhabitable for the stinkhorn fungus. Be careful when handling lime, as it is a caustic substance. Make sure to read the instructions on the package before applying it to the soil.
Precautions
Keep in mind that both the bleach and lime solutions are toxic and will likely harm or kill other plants in the area. They may also contaminate and damage your soil. Therefore, it is recommended to dig out the mushrooms and remove the surrounding soil before applying these treatments.
Additionally, always wear gloves when handling stinkhorn mushrooms to avoid any contact with their smelly spores. Place the removed mushrooms and soil in a sealed plastic bag and dispose of it with your regular trash.

Remove immediate soil
Stinkhorn mushrooms are a type of fungus with a very distinct and unpleasant smell. They are usually reddish-orange and can grow up to 8 inches tall. While they are not harmful to humans or pets, many people find them offensive and want to get rid of them.
If you have successfully removed the stinkhorn mushroom, the next step is to remove the immediate soil. This is because there may be spores or undeveloped mushrooms in the soil surrounding the removed mushroom. To do this, use a shovel to dig up the top layer of soil in about a 6-inch radius around the removed mushroom. Be sure to wear gloves to avoid getting your hands dirty and smelly.
If the stinkhorn mushroom grew in something other than soil, such as tree bark, mulch, or other loose decaying plant material, remove this as well. Use the shovel to dig out the mushroom's egg-shaped base, which is usually about the size of a golf ball. Place the excavated soil or other material into a plastic bag. Seal the bag shut and place it out for trash collection. Do not discard the fungal matter with yard waste, as the bag could rupture and allow spores to escape and create new mushrooms.
It is important to note that stinkhorn fungi are seasonal and do not last very long. They will eventually go away on their own. However, if you want to prevent them from coming back, there are a few control measures you can take. Stinkhorn mushrooms grow on rotting organic matter, so remove underground stumps, dead roots, and sawdust left from grinding stumps. The fungus also grows on decomposing hardwood mulch, so replace it with pine needles, straw, or chopped leaves. You can also try using live groundcovers instead of mulch. Additionally, make sure to remove any mulch or soil surrounding the stinkhorn, as spores can survive and grow in these materials.

Change the pH of the area
Stinkhorn mushrooms are a type of fungus that emits a putrid odour, likened to that of faeces, rotting meat, or a decaying animal. They are reddish-orange in colour and can resemble a wiffle ball, an octopus, or a straight stem. While they are not poisonous to humans or pets, they can cause allergy-related issues and attract flies and gnats.
Stinkhorn mushrooms grow on rotting organic matter, such as underground stumps, dead roots, sawdust, and decomposing hardwood mulch. They favour moist and mulch-covered terrain and are often found in yards where trees have been removed.
If you are dealing with stinkhorn mushrooms in your lawn, one option for controlling their growth is to change the pH of the affected area. Most mushrooms, including stinkhorns, prefer alkaline to neutral environments. By drastically acidifying the area, you can make it uninhabitable for the fungi. This can be achieved by tilling in large amounts of sulphur or other acidifying amendments. However, it is important to note that this method will likely kill most of your lawn, as it is considered the "nuclear option". Additionally, changing the pH of the soil can have long-lasting effects on the local ecology, so it is recommended to explore other control measures before resorting to this method.
Before attempting to alter the pH of your lawn, consider implementing some of the following preventative measures to control the growth of stinkhorn mushrooms:
- Remove underground stumps, dead roots, and sawdust from your yard, as these provide a food source for the fungi.
- Replace decomposing hardwood mulch with pine needles, straw, chopped leaves, or pine bark mulch.
- Avoid using fresh wood chips or sawdust in your landscaping. Instead, allow them to age for at least six months or compost them thoroughly before use.
- Water hardwood mulch well when it is first applied to encourage the growth of beneficial bacteria that can compete with fungi.

Pluck and discard them
Stinkhorn mushrooms are known for their unpleasant odour, which can be likened to the smell of faeces or decaying meat. They are usually reddish-orange in colour and can grow up to 8 inches tall. They are often found in lawns, mulch, and bare soil. While they do not harm plants or cause diseases, many people find them offensive due to their strong smell.
If you want to get rid of stinkhorn mushrooms in your lawn, one option is to simply pluck and discard them. It is important to remember that stinkhorns grow from egg-like sacks, so when removing them, you should dig beneath the mushroom to scoop out its egg-shaped base. You can use a shovel to dig out the mushroom and the surrounding soil, being careful not to leave any spores or undeveloped mushrooms behind.
To avoid spreading the spores, it is recommended to wear disposable gloves while handling the mushrooms. Place the plucked mushrooms and the excavated soil in a plastic bag, seal it shut, and then discard it with your regular trash. Do not discard the bag with yard waste, as rupturing or opening the bag could release spores and create new mushrooms.
While plucking and discarding stinkhorn mushrooms can be effective, it is important to note that they may still come back. Stinkhorns are challenging to eradicate, and even aggressive attempts to kill them may not always succeed. Additionally, they can be beneficial to your lawn as they contribute to recycling plant debris and improving soil fertility. Therefore, you may also consider leaving them alone, as they tend to disappear on their own after a few days.

Frequently asked questions
Stinkhorn mushrooms are short-lived and will naturally disappear quite rapidly. If you want to get rid of them immediately, you can pluck them from the ground and discard them. However, removing stinkhorn mushrooms will not eradicate them as they will continue to produce new fruiting structures. To prevent regrowth, you can pour a mixture of equal parts boiling water and bleach directly onto the fungus. Alternatively, you can sprinkle lime over the mushrooms and surrounding soil to make the area inhabitable for the fungus.
Stinkhorn mushrooms are reddish-orange fungi that emit a putrid rotting meat smell. They are found in lawns, mulch, and areas with bare soil.
Stinkhorn mushrooms are not harmful to your lawn or garden. They are neither poisonous nor do they cause plant disease. In fact, they are beneficial as they break down rotting material into a form that plants can use for nourishment.
Stinkhorn mushrooms grow on dead organic material. To prevent them from growing in your lawn, you can remove decaying organic matter, especially sawdust piles, dead roots, underground stumps, and hardwood chip mulch. You can also try to make the area unhealthy for mushrooms by drastically acidifying it with sulfur or another acidifying amendment. However, this may kill most of your lawn.
