Destroy Mushrooms In Your Lawn: A Guide

Mushrooms in your lawn can be unsightly, and even dangerous, especially if you have pets or young children. While mushrooms are beneficial because they break down organic materials and make nutrients available to other plants, some people may want to get rid of them. Mushrooms are part of a larger organism known as a fungus, which grows into or around its food source. They need two things to grow: food and moisture. If your lawn has poor drainage and lots of organic matter, mushrooms will likely develop over time.

Pluck mushrooms by hand or with a tool

Mushrooms are the fruiting bodies of a larger fungus organism that lives underground. While some people find them unsightly, mushrooms are not harmful to your lawn. In fact, they are beneficial because they break down organic matter and make nutrients available to other plants. However, some mushrooms are poisonous and harmful species may indicate the presence of pests or diseases in your lawn.

If you want to get rid of mushrooms in your lawn, one option is to pluck them by hand or with a tool. This method is suitable for small infestations as it can be time-consuming and laborious for larger areas. When plucking mushrooms, it is recommended to wear gloves as some wild mushrooms can cause skin irritation. You can then dispose of the mushrooms in a garbage bag.

To identify the type of mushroom you are dealing with, it is important to get a proper ID. Picking mushrooms can help with this process as you can examine their texture, firmness, and internal characteristics. Some mushrooms have different colour staining at the base of the stem, while others have remnants of an egg-like form from which the stem initiates. Additionally, some mushrooms have what appear to be roots. By plucking the mushrooms, you can gain access to these important identification features.

When plucking mushrooms, there are a few techniques you can use. One method is the "twist and pull" technique, which involves gently twisting and plucking the mushroom from the ground. This technique works well for about 80% of mushrooms and results in minimal bruising. However, some mushrooms are more deeply rooted, and twisting may cause heavy bruising or even shear the stem.

Another technique is to use a cutting tool, such as a knife, scalpel, or exact o, to cut the mushroom off at the base. This method is suitable for mushrooms with monster stem bases that are deeply rooted into the substrate. It helps to prevent damage to the substrate and reduces the risk of mould formation.

While plucking or cutting mushrooms can remove the visible fruiting bodies, it is important to note that it will not eliminate the underlying fungus. The fungus will continue to thrive as long as there is organic matter for it to feed on. Therefore, it is essential to address the underlying causes, such as removing decaying organic material and improving drainage, to prevent future mushroom growth.

Use a vinegar solution

If you're looking for a natural way to get rid of mushrooms in your lawn, a vinegar solution can be an effective method. This approach leverages the acidic nature of vinegar, which can create an unfavourable environment for mushrooms and prevent their growth.

To make a vinegar solution, mix one part vinegar with four parts water. For a stronger concentration, you can also try a one-to-one ratio, but always exercise caution as vinegar can be harmful to your lawn and other plants. It is recommended to use white vinegar, which is known for its effectiveness in killing mushrooms.

Once you've prepared the solution, transfer it to a spray bottle. This will allow for easy and targeted application directly onto the mushrooms you want to eliminate. Spray the solution liberally onto the mushrooms, ensuring complete coverage. You may need to repeat this process over several days to fully eradicate the mushrooms.

When using a vinegar solution, it's important to be mindful of its potential impact on your lawn and surrounding plants. Vinegar is non-selective, meaning it can harm any plant it comes into contact with. To minimise collateral damage, apply the solution carefully and precisely, focusing on the mushrooms themselves. Additionally, consider covering nearby plants or grass that you want to protect.

By following these steps and exercising caution, you can effectively use a vinegar solution to kill mushrooms in your lawn while minimising potential harm to your desired flora.

Baking soda solution

Baking soda can be an effective treatment for controlling mushrooms in your lawn. It is a natural fungicide that can help raise the pH level of the soil, creating unfavourable conditions for mushrooms.

To make a baking soda solution, mix one tablespoon of baking soda with one gallon of water. You can then spray this mixture directly onto the mushroom-infested areas of your lawn. Alternatively, you can sprinkle the baking soda directly onto the ground and then water the lawn.

It is important to note that this method may require multiple applications and may take several days to show results. Additionally, while baking soda can help eliminate mushrooms, it may also harm or kill grass due to the increased pH levels. Therefore, it is recommended to apply the solution directly to the mushrooms and monitor the surrounding grass carefully.

If the baking soda solution does not effectively remove the mushrooms, you can try other natural fungicides such as vinegar or neem oil. You can also explore commercial fungicides specifically formulated to control mushroom growth. However, always follow the manufacturer's instructions and take the necessary precautions when using any chemical products.

Apply a quick-release, inorganic nitrogen fertiliser

Mushrooms in your lawn can be an unsightly problem. While they are usually harmless, some mushrooms can be toxic, especially to pets and children. If you are unsure about the type of mushroom growing in your lawn, consult a local nursery or a horticultural expert for guidance.

One way to get rid of mushrooms in your lawn is to apply a quick-release, inorganic nitrogen fertiliser. While this may seem counterintuitive, as mushrooms thrive on high-nutrient soils, nitrogen speeds up their growth and life cycle, causing them to disappear ahead of their natural lifespan.

First, it is important to choose the right type of fertiliser. Look for a quick-release, inorganic nitrogen fertiliser that is specifically designed for lawn or garden use. Avoid slow-release or water-soluble nitrogen fertilisers, as these can have different effects on mushrooms and may not be as effective in speeding up their life cycle.

Next, calculate the amount of fertiliser you need based on the size of your lawn. As a general guideline, use 1 pound (453.59 grams) of nitrogen for every 1,000 square feet of lawn. You may also consider adding some phosphorus and potassium to enhance the fertiliser's effectiveness. A good ratio to follow is 3 parts nitrogen, 1 part phosphorus, and 2 parts potassium.

Before applying the fertiliser, ensure that you have removed any visible mushrooms from your lawn. Mushrooms can spread spores, so it is important to wear gloves and dispose of the mushrooms properly. Pull the mushrooms out by the roots, if possible, and place them in a plastic bag. Tie the bag securely and throw it into a trash can or incinerator.

Now, you can apply the fertiliser to your lawn. Follow the instructions on the product label for proper mixing and application techniques. Be sure to pay attention to any safety precautions listed on the package. Apply the fertiliser evenly across your lawn, focusing on the areas where mushrooms were present.

Finally, maintain your lawn by mowing and watering regularly. A well-maintained lawn will help prevent future mushroom growth. Remember that mushrooms thrive in damp, dark environments with abundant organic matter, so by keeping your lawn trimmed and free of debris, you make it less hospitable for mushrooms.

By following these steps and applying a quick-release, inorganic nitrogen fertiliser, you can effectively kill mushrooms in your lawn and prevent their return.

Remove decaying organic material

Mushrooms thrive on decaying organic matter, so removing this material from your lawn is a good way to prevent mushrooms from growing.

First, identify the decaying organic material in your lawn. This could include grass clippings, decaying plants, animal waste, tree stumps, old roots, construction debris, and thatch.

Next, you can remove the decaying organic material by digging up the lawn with power equipment, such as a tiller or a sod cutter. This method is effective but may require significant effort and time, especially for larger lawns. It is also important to note that removing the sod will result in the loss of organic material, which will need to be replaced to maintain soil health.

Alternatively, you can smother the grass by covering the lawn with plastic, newspaper, or cardboard. This method is more environmentally friendly than using herbicides, but it may take several months to kill the grass and decompose the organic matter. It is important to overlap the layers well to prevent light from reaching the grass. You can also wet the layers and cover them with grass clippings, compost, or mulch to help retain moisture and hold down the layers.

Another option is to manually remove the decaying organic material with a rake or a shovel. This method is suitable for small areas of grass but may be labour-intensive for larger lawns.

After removing the decaying organic material, you can take steps to prevent future buildup, such as regular lawn maintenance, proper watering practices, and avoiding the use of nitrogen-based fertilisers, which can contribute to the accumulation of dead matter.
