Identifying What Are The Tiny Mushrooms Growing In My Greenhouse

According to David Fischer, author of Edible Wild Mushrooms of North America: A Field-to-kitchen Guide, many mushrooms can grow indoors, mulch beds, or lawns. Correctly identifying the tiny or small ones growing in your greenhouse would be impossible, so below are the types of mushrooms that you can expect in the greenhouse conditions. 


Common mushrooms that grow indoors

A typical small mushroom that grows indoors is Leucocoprinus birnbaumii. You might also see it in your pots in the greenhouse, thus, giving it the name flowerpot parasol and plant pot dapperling. If you live in a temperate region, you have a higher chance of seeing this mushroom. 


Common mushrooms that grow in mulch beds

The mulch beds are also prone to having Clitocybe nuda, Coprinus atramentarius, Coprinus micaceus, and Lepiota cepaestipes. The smallest ones are the last two, and only the last one can cause short-term gastrointestinal symptoms. You can spot them in the greenhouse when the climate is warm. 


Common mushrooms that grow on lawns

Agaricus campestris and Agaricus placomyces are common mushrooms that grow on lawns or the ground of the greenhouse. While these fungi aren’t tiny as their caps measure 4 to 7 inches wide, it’s not surprising to see them growing in ideal conditions like the previous examples. They are also common in the Rocky Mountains of western North America.


Why Do Mushrooms Grow In The Greenhouse?

There are many potential reasons why you see mushrooms growing in your greenhouse. For starters, you might use potting soil contaminated with fungus and the conditions in your greenhouse is ideal for its growth. This is the common reason you see mushrooms in your pots, especially when the environment is cold, humid, and moist. 

But what about the mushrooms that grow in your raised beds in the greenhouse? It might be because of the organic matter in the bed, contamination with potting soil, airborne movement, or from your clothing. Overwatering can also cause mushroom growth in raised beds because the area becomes moist and humid. 


Are Mushrooms Bad For The Greenhouse?

Mushrooms are fungi, and seeing them in the greenhouse will naturally make anyone worried. However, the good news is that mushrooms are not bad for the greenhouse. They are harmless to your plants and even offer benefits for them. 

For example, they improve the quality of the soil because they help with its nutrient content. Unlike weeds, mushrooms won’t compete for the nutrients in the ground. Instead, they add compost by decomposing the organic matter in the soil. 

You can think of the mushrooms and plants having a symbiotic relationship. They provide nutrients and increase the plant roots’ surface area, and the plants will produce sugars as fungi food. However, do note that there are still harmful fungi in the greenhouse.

Mushrooms are the good fungi, while the white powdery mold is an example of a harmful fungus that can be detrimental for your plants. Overall, mushrooms aren’t bad for your plants, but it’s better to get rid of them since they can make the greenhouse unsightly. Additionally, other human beings and pets may consume mushrooms, which can be harmful as some are very toxic. 


How To Control Mushrooms In The Greenhouse

As mentioned earlier, overwatering is a leading cause of mushroom growth in the greenhouse. Remember that water encourages mushrooms to grow because they thrive best in moist and humid environments. At the same time, be aware of contaminating your potting soil or mulch beds since mushrooms can also be airborne or transferred via clothing.

It can be hard to remove mature mushrooms because they can release more spores. Therefore, you can only remove small mushroom caps or use fungicide in the greenhouse. Lastly, ensure proper ventilation and air circulation in the greenhouse to prevent fungal growth. 



The thought of fungi growing in your greenhouse is unappealing. You might end up contemplating what are the tiny mushrooms growing in my greenhouse and immediately search for its species. However, there are so many mushrooms, so identifying what you see correctly is tricky. 

A typical small mushroom that grows indoors is the Leucocoprinus birnbaumii. Other species may also thrive in the greenhouse, given that the optimal growing conditions are available. The good news is other than being unsightly, mushrooms aren’t bad for your plants. 

Be aware of the potting soil you’ll use as this can cause contamination in the greenhouse. Overwatering and poor air circulation are two factors that can also support mushroom growth.

Moreover, these trees thrive well in regions where the weather is mostly warm and sunny. However, don’t expect them to grow in areas that experience extreme temperatures during the summer and winter.


Avocado: The Superfood

Did you know that the global demand for avocados has been steadily increasing? Aside from the fact that its fruit is known for its full, buttery flavor and rich texture, it’s also packed with loads of essential nutrients that are good for your body.

A single serving of avocado fruit contains vitamin K, vitamin C, folate, potassium, vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin E, manganese, magnesium, iron, copper, zinc, and vitamin A.  It also has protein, fiber, and healthy fats. If you’re on a low-carb plant food diet, you’d want to incorporate avocados into your diet.


What are the Growing Requirements of an Avocado Tree?

Since avocado trees need to be grown in warm semi-humid climates, they only grow in U.S. Department of Agriculture (USDA) plant hardiness zones 8 to 11. However, it’s important to note that while avocado trees may be grown in those zones, they don’t always thrive well in areas that get extremely hot during the summer or frosty, chilly, or snowy in the winter. This implies that the ideal environment for an avocado tree should have moderate temperatures all-year-round.


What are the 3 Primary Groups of Avocado Trees?

If you’re planning to start an avocado farm, you need to know the 3 main groups of avocado trees: Guatemalan, West Indian, and Mexican. Each type has its own ideal growing range.


Guatemalan Avocados

A Guatemalan avocado is known for its hard skin that features plenty of warts.


West Indian Avocados

This type of avocado tends to flourish in warm climates. Unlike the Guatemalan avocado, a West Indian avocado has thin and shiny skin and could weigh up to 5 pounds.


Mexican Avocados

A Mexican avocado thrives well in tropical highland areas. Compared to the other avocado groups, the Mexican avocado is more tolerant of cold weather. In fact, it can manage to survive even when temperatures drop to 26˚F.

Moreover, this type of avocado produces smaller fruit that weighs less than a single pound and its skin has a distinct papery-smoothness to it.


Expert Tips on How to Start an Avocado Farm

Unless you’re willing to take on a long-term project, spend a considerable amount of money on planting, and wait for a period of 3 to 5 years for your first harvest, don’t get into avocado farming. However, if you’re willing to go through the whole nine yards to enjoy top yields for many years, check out this guide:


Tip #1: Plant them in areas where the temperatures are consistently cool

Be sure to plant your avocado trees in cool temperatures that can range between 68˚F to 75˚F on a daily basis to avoid fruit drop. However, when they’re flowering, or when they’re starting to bear fruit, the humidity levels shouldn’t go below 50% at midday.


Tip #2: They don’t like wind

In case you’re not aware, avocado trees have brittle branches that easily snap off. For this reason, it’s best not to plant them in areas that are mostly windy because wind can cause considerable damage to their fruit.


Tip #3: Most of them need proper irrigation

If your avocados are rain-fed, they need to have at least 1,000 mm rainfall spread out throughout each year. Before their flowering season, avocado trees require a drier season that lasts for about 2 months. On a weekly basis, avocado trees need about 25 mm water.

It’s extremely important to test the quality of irrigation water because if its pH and bicarbonates are really high, they trigger a build-up of free lime in the soil. You also need to remember that high levels of sodium and chloride can have a negative impact on your avocado plants.

Since the plant’s roots are shallow, the ideal way to apply water is via a micro-sprinkler or drip. This ensures an even distribution throughout the avocado tree’s root area.

Moreover, proper moisture control needs to be ensured in the root zone because this area tends to easily dry up.


Tip #4: Determine the soil’s suitability and prepare it accordingly

You can’t just plant an avocado seed on soil that hasn’t been prepared accordingly. To prepare the soil for planting, you need to dig soil profile pits throughout your farm. Make sure that the pits are 1.5 m deep.

Only a single put per ha is required. However, you need to dig more pits if the location is non-homogenous or hilly. Check the color of the soil, its texture, structure, patches, sitting water, concretions, hardpans, stones, and gravel.



Grow Your Avocado Trees in a Hobby Greenhouse!

Since avocado trees require specific levels of temperature and humidity, you’ll find it easier to grow them in a hobby greenhouse. The enclosed space allows you to customize the environment to meet the needs of your plants. What’s more, it protects them from strong winds and the constant threat of pests.

Learning how to start an avocado farm outdoors is great, but growing them inside a hobby greenhouse is even better.
