Maine residents didn’t see black mold on their lawns in over three decades. But thanks to a recent turn of events — including the weather, extreme freezing, and a drought-filled summer to follow — has turned up black mold once more, and it's wreaking havoc on many lawns throughout the state.

Black Mold is a fungus that can grow almost anywhere with enough moisture and organic matter. 

Here in Maine, we’re no stranger to mold, especially during the humid summer months. While some molds are harmless, others can cause severe health problems. In fact, black mold is a form of mold that can be particularly harmful. 

If you suspect that your lawn has black mold, it's essential to take action. This post will teach you how to get rid of black mold on your Maine property.

What is Black Mold (or Black Lawn)?

Mainers are noticing black mold on their lawns and are reaching out to professionals for answers. 

This particular strain of black mold (Cladosporium sp.) thrives in dry conditions, which explains why it is so prevalent this year. The hot, dry weather we experienced in June put a lot of stress on the grass, making it more susceptible to diseases like Cladosporium sp. 

While this fungus most often causes thinning and discoloration, it can also kill the grass. If you’re concerned about black mold on your lawn, reach out to your local Maine landscaper or lawn care specialist for advice on treating it.

Can the black mold spread from yard to yard?

Cladosporium sp., Maine’s black lawn culprit, can quickly spread from one yard to another through wind and water droplets.  

The black mold can cause extensive damage to properties, as it can kill grass and other plants. That’s why it’s essential to keep yards well-watered to prevent the mold from spreading. 

Additionally, black mold should be removed from lawns as soon as it’s spotted. If black mold is left untreated, it can quickly spread and cause significant property damage.

How to get rid of black mold in your Maine yard

To prevent black mold, it's essential to ensure you're watering your lawn often. During periods of little rain, your lawn will require extra watering. 

The best way to make sure your property is watered consistently is using a sprinkler on the lawn every couple of days, depending on how much rain your area has seen. 

Then, unfortunately, the places where you see black spots will need to be reseeded. These areas indicate that the grass is dead, and to make sure the black mold doesn't spread, reseeding is the best way to ensure healthy grass growth.
