Mushrooms in garden bed – a cause for concern?

Mushrooms, they’re weird-looking things, aren’t they? Some people love them, while others absolutely detest them. I for one think they’re absolutely marvellous and I enjoy them in a wide variety of dishes. Yes I know, we’re not talking about the taste of them, you’re wanting to find out if it’s ok for mushrooms to be growing in your garden bed… don’t fret, let’s find out together:

Mushrooms in garden bed

Fungi are the most common thing to develop in your garden beds. Not all fungi are mushrooms, but all mushrooms are fungi. Fungi growing in and around your garden beds are a strong sign that your soil is alive and healthy and provides a great environment for plants to thrive. You don’t have to be concerned about mushrooms stealing nutrients from the plants you’re cultivating since mushrooms aid with decomposition, making it easier for your plants to absorb more nutrients.

What are mushrooms?

As mentioned above, mushrooms are a type of fungi that generally grow in moist environments. They often have a short stem with a round or umbrella-shaped cap on top. The caps can be any color, but the most common ones you’ll see are white, brown or tan.

Mushrooms spread by releasing spores into the air and they will usually only grow in areas where the spores have landed. If you have mushrooms growing in your garden bed, it’s likely because there are already spores present in the soil. These spores develop deep fungal networks called mycorrhizae which help to support the growth of new plants by providing them with water and nutrients.

The mycelium, which are long web-like structures sometimes mistaken for roots, make up the main body of this network. The mushroom you see above ground is merely the fruiting body.

What is Mycelium, and how does it assist plants?

Mycelium is the vegetative part of a fungus, consisting of a network of fine white filaments (hyphae). The primary function of mycelium is to absorb nutrients from the soil. In return for these nutrients, mycelium provides plants with essential water and minerals.

Some types of mycorrhizal fungi can even help break down organic matter so that the plants can access previously unavailable nutrients. This means that mushrooms growing in your garden bed can actually improve the soil quality and health of your plants!

Will mushrooms compete with my plants for nutrients?

As I mentioned earlier, mushrooms and other types of fungi will not compete with your plants for nutrients. As decomposers, mushrooms form symbiotic relationships with your plants which essentially means that they help each other to grow.

By breaking down organic matter in the soil, mushrooms make it easier for your plants to access essential nutrients and moisture. This type of relationship, between plant roots and fungi, is called mycorrhiza and it’s advantageous for both plants and fungi. The plant gets better access to essential nutrients, while the fungi get a dependable food source.

Mushrooms also help to improve the structure of your soil by increasing its porosity and aeration. This is important because it allows roots to easily penetrate the soil and provides them with the airflow they need to stay healthy.

Many gardeners actually add mushrooms to their gardens deliberately in order to improve the quality of their soil. This practice is called mushroom composting and it’s a great way to recycle kitchen waste while providing your plants with valuable nutrients.

Reasons why mushrooms like raised beds

The lack of compaction

Another reason why mushrooms love raised beds is that the soil is not compacted. This lack of compaction allows for better aeration and drainage which again, creates a more favorable environment for mushrooms to grow.

The presence of organic matter

Another reason why mushrooms love raised beds is that they often contain a lot of organic matter. This organic matter can come in the form of compost, manure, or even leaves. The presence of organic matter is important because it provides mushrooms with the food they need to grow.

Shaded areas between beds

Mushrooms also love the shaded areas that are often found between raised beds. These shaded areas provide a cooler and more humid environment which is perfect for mushrooms.

Warmer soil temperatures

Another reason why mushrooms love raised beds is that the soil is often warmer. This is due to the fact that raised beds are often located in sunny areas. The warmer soil temperature is important because it provides the perfect environment for mushrooms and other plants to flourish.

Do mushrooms cause problems in raised beds?

Mushrooms are not a cause for concern, in fact, let’s outline the benefits of keeping them around in your:

  • Mushrooms have the ability to generate nutrients.
  • Mycelia have symbiotic relationships with your plants.
  • Similar to how worms help break down fallen leaves, mushrooms also play a part in the process.

1. Mushrooms can generate their own nutrients – This means that they don’t need to rely on plants to survive, and in fact, can actually help improve the soil quality for plants.

2. Mycelia have symbiotic relationships with plants – This means that mushrooms and plants benefit from each other, with mushrooms breaking down organic matter to help make essential nutrients available to plants, and plants providing a food source for mushrooms.

3. Mushrooms help break down organic matter in the soil – this makes it easier for plants to access essential nutrients and moisture. This is an important role as it helps improve soil structure and health.

How to stop mushrooms growing in raised beds

If you’re concerned about the mushrooms growing in your raised beds, there are a few things you can do to stop them.

1. Improve drainage – This can be done by adding more organic matter to the soil or by making sure that the bed is sloped so that water drains away from it.

2. Increase air circulation – This can be done by pruning back any plants that are blocking air flow, or by adding a fan to the area.

3. Reduce moisture – This can be done by avoiding overwatering the bed, or by covering the bed with a tarp during periods of heavy rain.

4. Remove mushroom-producing material – This includes removing any rotting leaves, or dead plants and only using well-rotted manure.

Conclusion

Mushrooms are not a cause for concern in raised garden beds, and in fact, can provide several benefits to the soil. So let’s sum-up everything we have learnt:

  • It’s typical for plants in your garden beds to develop fungus
  • Mushrooms and fungi growth in garden beds is a positive indication that your soil is healthy
  • Do not consume mushrooms from your garden beds without contacting an expert mushroom forager.
  • Fungi don’t take away nutrients from your plants – they help them better absorb them
  • Mushrooms help in the decomposition process
  • Mushrooms improve the structure of your soil by increasing porosity and aeration
  • Mushrooms provide nutrients and act as a natural fertilizer
  • Mushrooms do not cause a problem for your garden beds

People Also Ask

Are the mushrooms edible growing near my plants?

Nope, not usually! If you are looking to consume wild mushrooms, I would recommend that you speak directly to an expert mushroom forager because there are many mushrooms and fungi out there that can be poisonous if consumed.

Are the vegetables from my garden still safe to consume if there is fungi?

The plants in your vegetable garden will not make you sick if there are mushrooms and fungi growing nearby. The only way you could possibly become ill is by eating the fungi directly. The plants are actually pretty safe to consume even if there are fungi growing nearby.

What should I do with the fungi growing around my plants?

Nothing! There’s nothing for you to do except sit back and enjoy the benefits that these little organisms bring to your garden. It’s a great indication that your soil is teeming with life so don’t do anything! If you find mushrooms and fungi growing in your garden or garden containers, don’t worry about it – just let nature take its natural course.

Can you add mushrooms to your compost pile?

Mushrooms are a great addition to your compost pile because they help break down organic matter and make essential nutrients available to plants. Just be sure to add a variety of other materials to your compost pile as well, such as leaves, grass, and kitchen scraps.

Do all plants need fungi?

No, not all plants need fungi but many do benefit from a symbiotic relationship with fungi. Fungi help plants to better absorb nutrients and moisture from the soil so it’s beneficial for both the plant and the fungi if they are present.

Should I remove mushrooms from my garden?

You can either dispose of the mushrooms or let them rot away on their own; just don’t consume them. More mushrooms will likely appear in due time since the fungus that creates them is breaking down the organic matter you’ve added to the bed, which helps your vegetables rather than harms them.

Should I remove mushrooms from my flower bed?

While mushrooms are mostly harmless to your flower beds and grass, you might want to remove them. They can be rather attractive to children and pets because of their shape, color, and smell.

Do mushrooms grow in the same spot every year?

It’s no surprise that you’re seeing mushrooms in the same location year after year; this has to do with their biology. Mushrooms and fungi are really the fruiting body of a much larger network of spores that develop underground over time.
