Get Rid of Mushrooms in Garden Lawns the Easy Way

How Mushrooms Grow

The small umbrella-like living things that you see coming out in your yard are mushrooms. They are often associated in movies as abodes of fairies and toads.

What you see on the sides of dead trees and staircases that are seldom reached by sunlight are also mushrooms. Well, I assume you already know this right from the start, right?

This explains why they appear abundantly during the rainy season or when you water your yard too often. They are likewise evident in parts where there’s animal dung or grass clippings that are decaying.

New lawns usually have a lot of moisture as a lot of water is needed to foster the growth of roots underneath the soil.

When mushrooms spores have been living in the sod even before it was laid down and watered, they will naturally germinate once they are positioned.

After which, they start to break down organic nutrients and materials in the lawn and underneath the soil. Once these fungi have amply grown, mushroom will start bursting out and showing up.

What Keeps Mushrooms Alive?

Dead matter

Mushrooms do not rely on sunlight in order to grow. They will remain alive and kicking as long as there are lifeless organic matters to consume.

Fungi are capable of breaking down dead leaves and dead branches, trunks, and trees, which makes them the best decomposers on Earth.

Once there’s a dead matter in your lawn, expect to see mushrooms. Maybe you’re asking if it’s good or bad.

It is good because it only means that you’re standing on healthy soil. At the same time, it’s also bad because it’s destroying your lawn.

Water

As already mentioned earlier, mushrooms are evident in areas that have a high retention of moisture. After a rainy day, they would crop up and begin to be noticed.

The growth of mushrooms is inevitable during the rainy season or when you just laid down your sod where you need to water it every now and then.

But this can actually be reduced by removing the excess nutrients that feed the fungi. Make sure to pick up and dispose of all dead leaves, branches, and animal excrements, if any.

Types of Mushrooms that Grow in Yards

Mushrooms belong to the family of fungi and its species has a long list. In fact, according to Bob Vila, there are at least 38,000 types of mushrooms alone, which are classified as either toxic or non-toxic.

However, not all these types of mushrooms grow in the yard. The three types that usually grow in yards are the death angel mushrooms, meadow mushrooms, and horse mushrooms.

Death angel mushrooms are those that have white caps and gills – they are the toxic type.

The meadow mushrooms, on the other hand, have white caps and dark brown gills.

Lastly, mushrooms that have creamy white caps are known as horse mushrooms, and they are edible and harmless.

Lawn mushrooms do not just include those that are classic-shaped. There are the bird’s nest mushrooms that look like small nests that are packed with fungal eggs.

Also included are the elfin umbrellas, join puffballs and many more.

Be watchful of mushrooms that grow in lawns especially if you have kids or pets. Some toxic or poisonous mushrooms include the green-spored mushrooms and the lawnmower’s mushroom.

Maybe you’ve also heard of mushrooms with rings around them – don’t eat them as they are not edible. If eaten, they can cause an upset stomach and even death.

How can these deadly mushrooms be avoided and controlled? Simply do a frequent check on your lawn.

If you ever find such fungi, uproot them and place them in an area where no one can have easy access to them, or better yet, discard them using a garbage bag.

Mushrooms in Grasses and Flower Beds

Are mushrooms good or bad? Mushrooms sometimes look good in between grasses and flower beds because the they offer contrast. But unfortunately, many people find them more of an annoyance than an advantage.

The toxic mushrooms that cause upset stomachs are the ones that need to be eradicated. They need to be ripped up immediately before your kids and pets get tempted to play with them or, the worst, eat them.

But then again, not all mushrooms are toxic. Some of these fungi are not distressful.

As per the Statewide Integrated Pest Management Program of the University of California, poison-infested fungi in lawns or gardens hardly ever form structures that are mushroom-like.

Most mushrooms actually serve as support in lawns. They remain undetected until they become fully grown and ready for reproduction.

Wiping out mushrooms

Killing mushrooms that flourish in grasses and flower beds does not affect their entire population since they only represent a tiny part of it.

There are fungicides that may be used for controlling the growth of mushrooms but they are not usually allowed to be used in homes because of their chemical contents that are hazardous to one’s health.

So, instead of using fungicides, it would be safer and better to just alter the conditions that promote the increase of the mushroom population.

The most important thing to do in wiping out mushrooms is to start diminishing the ring mushrooms followed by the non-toxic ones.

Remove the thatch and aerate the lawn within the area. Get rid of them before they even start growing. Read more about aerating lawns here.

Better be safe than sorry

Mushrooms do not harm grasses and flower beds, but it is much safer to get rid of them. Yes, they have fascinating colors and shapes, and they even have an attractive smell, which may entice kids and pets to play with them.

Also, when handling mushrooms, better use gloves and wash your hands meticulously after that especially if you aren’t sure what type of mushroom you’re dealing with.

5 Best Ways to Effectively Kill Mushrooms in Your Lawn

1. Remove excess moisture in your lawn

Mushrooms like to exist in wet environment. So, as much as possible, lower the amount of moisture in your area. Do not soak your lawn with water as this can greatly trigger the growth of mushrooms. Adequate water will do.

Another way to lessen moisture is to set up a French drainage. This type of ditch is occupied by stones that has a pipe underneath them, which serves as the waterway.

Having this type of draining will allow water to escape from your lawn, leaving it only with the right amount.

You also might want to check the spouts around your lawn for swarming waters as they also cause moisture, and eventually, the growth of mushrooms.

2. Eliminate dead matters

When there are decaying things in the different areas of your lawn, mushrooms will surely occupy them. Rotten things are what mushrooms consider as their comfort food.

This is the reason why dead matters have to be taken out from your yard immediately, if possible.

After mowing the grass, for instance, the clippings should be thrown right away. Use a garden rake for grass clippings and place them in a garbage bag.

You should also make it a habit to pick up the wastes of your pets – don’t just leave in your lawn and wait for them to decompose. Remains or branches of trees also have to be removed.

To expedite the decomposition of cut grass or fallen leaves, you may use nitrogen fertilizer. 1 to 5 pounds of nitrogen fertilizer can already cover 1,000 square feet of lawn.

To fully ensure the discontinuance of the growth of mushroom, remove the mushrooms all the way to their roots.

3. Increase sun or light exposure

You should already know by now that mushrooms like to stay on shady and damp areas.

To resolve this, you can effectively reduce or eliminate mushrooms or fungi by allowing a good amount of sunlight to hit your lawn.

Cut or trim tree branches that impedes the rays of the sun from touching the areas of concern.

4. Aerate moisture-rich areas in your lawn

Compacted soil traps moisture, which makes it the perfect place for mushrooms to bud. If there seems to be an increasing number of fungi in your lawn, aerating the soil in your lawn will be good idea.

You can either use a rake or shovel to perform aeration. But if want a less tedious way, you may use an aerator.
