Raise The pH Level

The pH level of your soil (the measure of how acidic or alkaline a substance is) affects the growth of your plant. The pH scale ranges from 0 to 14, with 7 being neutral. 

Lower numbers are more acidic and higher numbers are more alkaline. Mushrooms can grow in acidic soils, but not as well as they do in neutral or slightly alkaline soils. 

So if you want to keep mushrooms out of flower beds and away from other plants, raising the pH level will help prevent their growth.

Use A Fungicide

Fungicides are chemical agents used to kill fungi or fungal spores. Organic fungicides derive from plants, animals or minerals, while synthetic fungicides are made in a laboratory. The type of product you need depends on what kind of fungus is threatening your plants:

If the fungus is causing leaf spot (also known as leaf blight), powdery mildew or rust diseases on your flowers and vegetables—such as tomatoes, cantaloupes and roses—you’ll want an organic solution such as neem oil spray. 

Another effective organic control is horticultural vinegar spray because it contains acetic acid (a natural compound found in fruits). When using this type of product, be sure not to mix it with an oil-based solution because they will react negatively together!

Rake And Clean

As the mushrooms begin to appear, you’ll want to start raking up the mushrooms and any other debris that has fallen into your flower bed. 

Rake up as much of it as possible, then use a brush or rake to remove any remaining spores from the bedding. 

Make sure you clean all tools thoroughly with soap and water after using them on your garden beds; even though there are no known cases of humans getting sick from ingesting wild mushrooms in this way, it’s better safe than sorry!

Add Lime Or Sulfur

When adding sulfur and lime to your soil, you should be sure to apply them in the fall. Sulfur is a good choice for planting beds that have been affected by mushrooms in the past, as it’s a natural fungicide. 

It works best when combined with lime and other fertilizers, but you can use sulfur on its own if necessary.

When applying sulfur, use 2 pounds per 1,000 square feet of area being treated. You should also incorporate this into your soil before planting anything new or planting seeds that require an acidic environment (such as tomatoes). 

Sulfur will not harm plants or animals over time; however, repeated applications may increase levels of toxicity in your soil over time so avoid applying too much. 

Lime is another common solution for dealing with mushrooms it’s applied similarly to sulfur but has slightly different effects on your plants depending on how much is used and when it’s applied during the growing season:

Aerate Your Soil And Add Organics

Aerating your soil is a simple process that you can do on your own. Aeration helps the soil to breathe, which means that oxygen and water will be able to reach the roots of your plants better. 

You can aerate by using a tiller or you can also use a spade or garden fork to break up the top layer of soil. If you already have well-aerated soil, then this isn’t necessary for you—but if not, it’s a good idea to do so.

Organic matter is important for any bed because it improves drainage and helps retain moisture in sandy soils or clay ones that are too compacted. 

You can add organic matter by mixing compost into topsoil before planting (it adds nutrients), or by simply adding straw mulch after planting (it prevents weeds).

Remove Mushrooms When They Appear

Remove mushrooms when they appear. If you catch the mushroom before it releases spores, you can simply remove it by hand or by using a rake.

Mushrooms are the fruiting body of a fungus and will grow anywhere there is available moisture and nutrients. They may also appear in your flower bed if you have ever planted mushrooms intentionally in your yard or garden (which is not recommended).

Keep Your Garden Clean

You can help prevent mushrooms from appearing in your flower beds by keeping your garden free of any debris, weeds, and leaves. 

If you have a compost heap, make sure it is regularly turned over and the contents are kept dry.

If you do find mushrooms growing in your yard, don’t panic! Some people use them as food or medicine. You can always get rid of them if they’re not something that interests you—just dig them up with a trowel or shovel.

Change The Soil Composition

You can change the soil composition to prevent mushrooms from growing in your flower beds. If you have a lot of flowers, try using compost or manure. 

Compost and manure are both great for gardening because they contain beneficial microorganisms that help plants grow better. Compost and manure also improve drainage and soil structure, which helps to prevent waterlogging.

To keep moisture levels consistent in your plant beds, add mulch like hay or straw around the base of each plant bed that you want to protect from mushroom growth (or just around all of them!). 

Mulch acts like an insulating blanket for soil it keeps it moist without letting moisture pool up underneath it after rains fall during winter months when temperatures fluctuate between warm days followed by cooler nights.

Plant In Raised Beds

Raised beds are a great way to grow flowers and vegetables, regardless of whether you have a large or small space. 

Raised beds can be made of wood, plastic or stone. If you choose to make your own bed, it’s best to use a rot-resistant material such as cedar or redwood because they will last longer than pressure-treated wood (which may have chemicals that leach into the soil).

You can also purchase pre-made raised beds from home improvement stores like Lowe’s and Home Depot. These come in many sizes and shapes so there’s definitely something for every yard!

Because raised beds drain better than in-ground gardens, it’s important for your soil pH levels not to fluctuate too much between seasons when planting vegetables or flowers in springtime. 

A good rule of thumb: if soil is acidic at 7 on the pH scale during winter months (when plants go dormant), then it should remain acidic throughout summer months when they’re actively growing again.

Use Cardboard, Plastic Or Newspaper Mulch

If you have mushrooms in your flowerbed, it can be tempting to fight fire with fire by using them as mulch instead. However, this won’t work very well because mushrooms are not plants and don’t do much good for plants. 

The best way to use mushrooms is on a pizza or in a salad! Mushrooms will not grow in plastic or paper that’s been used as mulch because they are porous materials that allow air and water through them (the opposite of what we want). 

And since they’re porous, they will allow weeds to grow through them too (which also defeats our purpose).

Mushrooms are great at keeping soil moist so it’s best to use them as an organic weed barrier between beds of vegetables such as kale or spinach. 

They can also be used as natural winter protection from frost by covering the ground immediately after harvest; just be sure not to let any light shine through your layer of pine needles/pine straw before covering with another layer filled only with mushroom spores so that there are no gaps for bugs trying their hardest not.

Use A Mushroom Repellent

If you’re looking to keep mushrooms out of flower beds and don’t want to resort to chemicals, here are some things that can help:

A mushroom repellent. This is kind of like a garlic spray—you make it with fresh garlic and water, then spray the area where you don’t want mushrooms growing. You’ll have to reapply this regularly (every couple weeks).

Fungicide. Most fungicides won’t get rid of all the soilborne fungal spores in your yard; they just kill them as they try to grow from those spores into mycelium on top of the soil’s surface. Fungicides need regular application as well (weekly or biweekly).

Copper sulfate solution sprayed on plants’ roots will kill many kinds of fungi but not all kinds—and it has been known by some gardeners as “the green death.” This is probably not something you want around children or pets unless there’s no alternative! 

It may also burn tender young plants’ leaves if applied too close together in time or concentration levels during application seasonally; however, if used properly (follow directions!) this is an effective way to reduce populations in particular areas without affecting whole plant populations negatively if done properly annually throughout growing seasons


These tips should help you keep mushrooms out of your garden. It can be frustrating to find mushrooms in your flower beds, but if you take the time to keep them away from your flowers, you’ll be able to enjoy their beauty for years to come!
