Mushrooms in your yard can be unsightly, especially if you are preparing to sell your property. While they usually do not damage your lawn, their presence may signal potential problems with your grass. Mushrooms are caused by moist conditions combined with high levels of nitrogen from decaying organic material like leaves or grass clippings in your soil. Poor drainage can also lead to mushroom growth by increasing the amount of moisture available for fungi to thrive on. To kill mushrooms, you can use vinegar, which is a natural fungicide and herbicide due to the acetic acid within it. However, not all vinegar is created equal. To effectively kill mushrooms, you should use horticultural vinegar, which has higher pH levels.

What You'll Learn

Use horticultural vinegar, which has a higher pH level
Horticultural vinegar, which has a higher pH level, can be used to kill mushrooms in your yard. However, it's important to note that vinegar needs to have a pH level of 1 or 1.2 to effectively kill mushrooms, and most household vinegars are not strong enough. When using horticultural vinegar, it should be diluted with water and applied with a spray bottle. It's crucial to use precision during application, as vinegar can harm surrounding plants. Wear protective gloves and clothing to shield your skin from the vinegar.
To create the vinegar mixture, mix one part horticultural vinegar with four parts water in a spray bottle. Mist the soil where the base of each mushroom was, sticking out of the ground. Repeat this process for five days to ensure the mushrooms do not grow back.
It's important to address the underlying conditions that encourage mushroom growth. Mushrooms thrive in moist, humid environments, so improving yard drainage is crucial. This can be achieved through aeration, which involves punching tiny holes in the ground to enhance water circulation and create a healthier soil environment less conducive to mushroom growth.
Additionally, removing decaying organic matter, such as leaves or grass clippings, from the grass can hinder mushroom growth. Mushrooms also tend to grow in mulch, so if they are predominantly growing in this area, you may need to treat your mulch with a baking soda solution or consider replacing it.
While vinegar can be effective, it's important to remember that a small patch of mushrooms is actually beneficial for your lawn, indicating healthy soil.

Mix one part vinegar with four parts water
Mushrooms thrive in moist conditions with high levels of nitrogen from decaying organic material, such as leaves, grass clippings, and animal excrement. They can be a nuisance, especially if they are toxic, and can cause turf disease if the soil is too soggy. While most mushrooms won't harm your yard, you can use vinegar to get rid of them.
To make a vinegar solution to kill mushrooms, mix one part vinegar with four parts water. Use a spray bottle to mist the soil where the mushrooms were growing. You should do this for five days to ensure the mushrooms don't grow back. However, be careful not to get the vinegar solution on your plants or grass, as vinegar can damage and even kill them.
You can also try other methods to prevent mushrooms from growing. Firstly, ensure your yard has proper drainage. If your lawn holds too much water, redirect excess water to a more desirable location, add a pond or water garden, or place rain barrels beneath waterspouts. Secondly, clear out the thatch, which is a buildup of living and dead grass that limits air circulation and inhibits water movement into the soil. You can do this by aerating your lawn with a manual core aerator tool, a vertical mower, or a power rake.

Spray the mixture directly onto the mushrooms
To kill mushrooms in your yard, you can use a mixture of vinegar and water. The vinegar acts as a natural fungicide and herbicide, with the acetic acid in the vinegar killing the mushrooms and preventing them from returning.
It's important to note that not all vinegars are created equal. The type of vinegar you use is crucial to the success of this method. Avoid using common household vinegars like white wine vinegar or apple cider vinegar, as these are often heavily diluted and have low pH levels, making them ineffective against fungi. Instead, opt for an industrial-type vinegar called horticultural vinegar, which has higher pH levels and is more effective at killing mushrooms.
When preparing the mixture, mix one part vinegar with four parts water. Always wear protective gloves and clothing when handling vinegar to protect your skin. Once you've prepared the mixture, pour it into a spray bottle.
Now, you're ready to spray the mixture directly onto the mushrooms. Ensure you cover the mushrooms entirely, including their bases. The vinegar will disrupt the membrane layer of the mushroom, causing it to dehydrate and eventually die. For best results, repeat the application every few days until you notice a reduction in mushroom growth.
Additionally, you can improve your yard's drainage to prevent mushroom growth. Mushrooms thrive in damp and humid environments, so ensure your lawn drains properly. Consider aerating your lawn by perforating the soil with small holes to increase drainage and decrease moisture retention.

Wear protective gloves and clothing to protect your skin
When preparing to apply vinegar to kill mushrooms in your yard, it is important to wear protective gloves and clothing to safeguard your skin. Mushrooms thrive in damp and humid environments, so it is likely that your yard will be moist when treating it with vinegar. This means there is a risk of your clothing becoming stretched or wet, reducing its protective abilities and exposing your skin to potential harm from mushroom spores and the vinegar solution.
To protect your skin, opt for long-sleeved shirts and long pants made from densely woven cloth. Fabrics such as denim, canvas, wool, or synthetic fibres are ideal as they offer more protection than sheer, thin, or loosely woven cloth. Dark colours provide superior protection compared to light colours, so consider wearing a dark, long-sleeved denim shirt, which can offer excellent protection with a high SPF.
Additionally, choose loose-fitting clothing to ensure maximum protection. Tight clothing can stretch and create gaps between the fibres, allowing more substances to pass through and reach your skin. It is also advisable to wear protective gloves, such as latex gloves, to prevent direct contact between your skin and any harmful substances.
By taking these precautions and wearing appropriate protective gear, you can minimise the risk of exposure to your skin while applying vinegar to kill mushrooms in your yard. Remember to also follow safety guidelines and instructions provided by the manufacturer when working with any chemical solutions.

Repeat the application every few days
To effectively kill mushrooms in your yard using vinegar, repeat the application every few days. Mix one part vinegar with four parts water, transfer the mixture to a spray bottle, and apply it to the infected area. You can also mist the soil where the base of each mushroom was sticking out of the ground. Continue doing this for five days to ensure the mushrooms don't grow back.
It is important to note that not all types of vinegar are suitable for killing mushrooms. The typical vinegar used for salads and dishes, such as common white wine vinegar or apple cider vinegar, may not be effective due to their low pH levels and heavy dilution. Instead, opt for a vinegar with higher pH levels and a stronger concentration, such as horticultural vinegar, which is specifically designed for gardening purposes.
Additionally, vinegar can be harmful to your grass and other plants if applied too heavily. To prevent damage to your lawn, use precision when spraying the vinegar mixture onto the mushrooms or affected areas. It is also crucial to address the underlying factors that encourage mushroom growth, such as poor drainage, lack of nutrients, and shady spots. Mushrooms thrive in damp and humid environments, so improving drainage can help reduce their recurrence.
By repeating the vinegar application every few days and addressing the environmental conditions that promote mushroom growth, you can effectively eliminate mushrooms from your yard and prevent their return.
