First, let’s understand why these mushrooms are growing in the first place. Before we get to the remedy it’s important to know the cause. Mushrooms are a type of fungi that grows from spores. Spores are microscopic organisms that produce asexually. 

The main reason mushrooms are growing on your lawn is moisture. Mushrooms need moisture to survive. For this reason, mushrooms usually grow during the rainy seasons.

However, mushrooms don’t need a proper reason to grow. As long as moisture and nutrients are present these fungi will find their way into existence.

Most of us have baking soda lying around in our house for baking reasons. But this chemical can be used for a lot more.

How To Kill Mushrooms Using Baking Soda?

Now that we know how it works it’s time to apply the process. All you need is baking soda and a spray bottle. Now follow these steps: 

Step 1: Make the mixture 

Take a gallon of water and mix two teaspoons of baking soda with it. 

Step 2: Use a spray bottle 

Using a spray bottle will give you the best results. You want the mixture to spread out evenly and a spray bottle does that job much better than pouring it all in. 

Step 3: Monitor if the mushrooms have died out

Step 4: Pull the dead mushrooms out of the soil

The final step is to pull the dead mushrooms out. Baking soda will kill the mushrooms but you will have to pull them out yourself. Take a basket or dustbin and put the dead mushrooms in it. 

And just like that, you have successfully killed all the mushrooms on your lawn. Remember, it will take some time and patience is the key. 

Using Vinegar To Kill Mushrooms

Another way of killing mushrooms is using vinegar. Using vinegar to kill mushrooms is just as simple as using baking soda. In a lot of ways, they’re the same thing. 

For this process, use a high concentration of vinegar and mix it with water. Make sure the balance between vinegar and water is even or you might risk the lawn’s acidity rising. One thing to be careful of is, that vinegar can harm the grass of your lawn so it’s best not to use too much of it. 

Just like the baking soda process, use a spray bottle and spray the mixture all over and around the mushrooms. Now, give it time and the mushrooms should die out.

The only downside of this process is vinegar is a much more powerful chemical than baking soda. So use it with much care and caution. 

How To Manually Get Rid of Mushrooms From Your Lawn?

We’ve talked about two fungicides today. Both of them work quite well but if you don’t want to use fungicides you will have to manually get rid of the mushrooms.

In some cases when the manifestation increases using some manual methods is more recommended. Let’s talk about what those are: 

1. Take immediate action 

As soon as you notice a mushroom, just take it out. 

2. Apply fertilizer 

Mushrooms feed off decaying organic matter. When you apply fertilizer the soil regains health, which interrupts the growth of mushrooms. 

3. Keep the lawn dry

Mushrooms grow on your lawn when the lawn is wet and dirty. Remember mushrooms need moisture to survive. Eliminate that and you’ll eliminate the mushrooms. 

4. Keep the lawn clean 

Keep the lawn as clean as possible. As we learned, mushrooms feed off dead matter. For this reason, keeping your lawn is very important to keep unwanted guests away. 

If you can eliminate the growth of the mushrooms you won’t have to go through the whole process of removing them. Hence, make sure the lawn is clean and dry.
