Why Is There Mold in Compost?

A little bit of the smell of mold in compost is a normal and healthy option. In fact, having mold in your compost is a sign that your system is operating exactly as it should. Since mold is a kind of fungus, it offers visible evidence that the microorganisms that live in your compost are performing their work.

Alongside these bacteria, which break your food down, the mold (a kind of fungus) is also involved in this crucial job. The fungi are significant as they can break down more brutal substances, which organisms could then target. 

There are various kinds of molds that can be found in compost. They differ in size, color, and form. Pink, white, green, and red mold are the most commonly found; however, you may be able to spot some that look powdery, ashy, or even slimy-looking. Find out more about why there is mold in the compost, as well as the warning signs to look for.

Reasons for Mold in the Compost

The presence of mold in compost indicates a good breakdown of your compost. It’s not a reason to be worried, as it’s all an element of the normal process that creates the nutritious soil you require to grow your crops.

They are all over the place, and air currents transport them. A damp, dark space is the ideal place for mold spores to grow. Thus your compost pile provides the perfect place to grow it. Be sure to incorporate the mold into the biomass, and be on the lookout for other signs of trouble so that you can take care of these before they become an issue.

Is Mold safe?

If you are new to making compost, even a little amount of mold could be alarming. Naturally, you will be worried. The problem with moldy compost is that it is not worth worrying about. It is, in fact, a natural phenomenon. Mold is a sign that your compost is fulfilling its biological purpose.

If, however, the mold begins to spread, this is a sign that your compost is not in equilibrium. Usually, just mixing your compost by pushing it further into the decaying material is enough.

The mold you find in the compost is not likely to cause harm. But, some people might be allergic to mold spores, and you should consider wearing an eye mask while working with your compost.

It is also crucial to keep in mind that you should not ingest the mold. Unlike edible, the fungi can make you and the animals in your yard sick when it’s eaten. But it is not harmful to the plants. And you can consume the fruit that grows in soil with soil and microbes.

How to Identify if Your Compost is Bad?

Your compost pile is functioning correctly, with little or no smell. A sour smell is a clear indication that something isn’t working correctly.

If something is rotting, you will smell it. However, compost made with the right proportions of brown and green substances produces very little smell. It should not be odorless enough to make you notice.

If your compost smells unpleasant, it is probably due to the fact that it’s not sufficiently moist. This can lead to anaerobic digestion, which creates poisonous, primarily sulfurous gasses. 

How to Fix Struggling Compost? 

The air exchange is limited when you have an open-air container. It is crucial to keep compost in a ventilated area. Rotating compost using a pitchfork or a shovel frequently will increase airflow.

A bad smell could indicate that your compost isn’t moist enough. To remedy this, add more brown materials like dried leaves, which help absorb water. If you are searching for more about composting, you can read our other posts on composting.

How to Know When Your Compost is Ready?

After the compost has passed through every breakdown stage and has stopped producing heat, it’s ready to be spread in your backyard garden. The mixture must have a distinctive earthy scent that is not similar to the organic elements that it is made up of.

The compost that is finished should appear like a homogenous mass. The compost is ready if you can see huge chunks or pieces of organic matter that haven’t been broken down. However, more dense materials such as corn and wood chips might remain visible because they are more difficult to degrade.

Signs that Mold is causing problems

Most kinds of mold (or bacteria resembling mold) aren’t an issue. However, in certain instances, mold can cause problems or excessive amounts of mold. Composting is about balance, and If your compost isn’t balanced, you will need to make adjustments.

When you observe a strong smell, lots of bugs, green mold, and soft compost, it means it’s because your compost may not be receiving enough air.

This could be because it’s compacted and may require aeration or because it’s too wet. In both instances, it is recommended to add dry brown material (leaves and cardboard.) into your compost bin and give the compost a good mix to break up the chunks of sludge. Do not water your compost pile, and be sure to cover it if you expect it to rain.

Precautions While Dealing Molds

Although molds are a normal component of composting, it is vital to stay clear of breathing the spores.

The best exposure to mold will occur when you sort your compost. Those who suffer from allergic reactions (especially mold-related allergies) or respiratory problems must be extra cautious since mold exposure could result in a severe reaction. Consider wearing a suitable mask to keep mold spores away. Avoid turning your compost in windy weather. 

Mold can also cause pets to become sick. So keep your pets away from compost, whether in the form of a pile or a bin. As per the American Society for Prevention of Cruelty and Abuse to Animals (ASPCA), the illness can develop very quickly and be life-threatening; therefore, you must contact your vet immediately when you suspect your pet consumed mold-contaminated food.
