You can help this process by removing any obvious sources of decaying matter, such as old rotten stumps, tree branches, animal waste, grass clippings, and thatch regularly with a thatching rake.


    Another natural way to kill off mushrooms in your yard is to use vinegar. Household vinegar or cooking vinegar is usually too diluted to be effective, so you will need to use horticultural vinegar, which tends to be 30-50% concentrated.

    Dilute the horticultural vinegar to a ratio of 4 parts water to 1 part vinegar. You can put it in a spray bottle for ease of application. You will probably want to wear eye protection and gloves because vinegar at this strength can burn skin.

    Cleaning up your mulch is also a good idea. This is because, while having mulch in your yard does help your grass in some instances, its purpose is to keep the soil temperature down and retain moisture, which creates the perfect environment for mushrooms to grow.

    While some organic materials, such as plant residues and manure, can improve the health of your soil and plant and are therefore beneficial, if you wish to reduce mushroom growth in your yard, it is best to remove as much organic material from your yard as possible at least for the time being so that you are able to reduce the mushrooms food source.

    Trim Your Trees And Shrubs

    Mushrooms prefer growing in the shade, so this is an important precaution if you have mulch around your trees and shrubs. Using loppers or pruning shears, trim the thin branches growing at the bottom of your plants, and use hand saws for the thicker branches. This way, you will also ensure that your mulch has time to dry a bit in between waterings, which will prevent it from becoming too damp.

    Using Industrial Vinegar To Kill Mushrooms

    As we mentioned previously, not all vinegar is made equal, and if the pH levels arent high enough, it wont work to kill the mushrooms effectively. Most household vinegar is around 5% concentration so youll want to use a vinegar that is at least 10% or higher when attempting to kill mushrooms with vinegar.

    While higher concentrations of vinegar will be more effective, its also important to mention that using concentrations that are too high will likely kill your grass as well as damage the soil in that area.

    Just remember that more doesnt always mean better, and while very high concentrations may work to get the job done, they could have negative repercussions on your lawn and garden.

    A popular option that many gardeners and homeowners use for this is Green Gobbler Ultimate, which is a 30% vinegar concentrate often used as a weed killer and natural fungicide. This is an all natural corn based vinegar solution that comes in a 5 gallon pail which gives you a lot of bang for the buck.

    Another great option with a spray trigger included is the 30% Vinegar Concentrate by PF Harris. Not only is this safe for the environment and completely natural fungicide, but can also work as a wonderful indoor cleaning solution.

    Regardless of which vinegar solution you choose, make sure to take necessary precautions before using these solutions. By no means should you ever inhale or ingest concentrated vinegar like these as they are deadly.

    Install A Proper Drainage System

    If you see a sudden growth of mushrooms in your lawn, it could mean that there is no proper drainage system for the soil.

    In turn, this could cause excessive wetness leading to more moisture and mushrooms.

    There are a few solutions to draining your soil, requiring you to install a French drain or dry creek bed to prevent flooding. You could also clean the gutters so that there is proper water flow.

    Its easy to tell where the hyphae are due to the brown circular ring pattern that appears in the grass. These spots indicate that there is a deeply rooted network of grown fungus spores and the grass cannot thrive. Mushrooms can also decompose in your yard, causing undesirable smells. Some species also smell bad when living and can attract flies.
