You’re enjoying a nice walk across your lawn when suddenly—mushrooms! They pop up overnight, like tiny umbrellas scattered throughout your grass. While they might look suspicious (or even magical), mushrooms in your lawn aren’t always the enemy. In fact, they can be a sign that something good is happening underground.

At MissionGreen Services, we often get questions about mushrooms. Are they harmful? Should you be worried? Let’s break it down:

Why Do Mushrooms Appear in Lawns?

Mushrooms are the fruiting bodies of fungi that already exist in your soil. They’re more common than you might think and appear when certain conditions align—moisture, organic material, and shade.

Common Causes:

• Excess moisture or heavy rain – Mushrooms love damp conditions.
• Poor drainage – Waterlogged soil creates the perfect fungal habitat.
• Thatch build-up – Decaying organic matter feeds fungi.
• Shady areas – Less sunlight means longer moisture retention.
• Old tree roots or buried wood – Fungi help break down decaying materials underground.

Are Mushrooms Harmful?

Generally, no—they’re not damaging your grass. In fact, they’re a sign that your soil is biologically active and decomposing organic matter, which improves soil structure. However, some mushrooms may be toxic if ingested by pets or children, so it’s understandable to want them gone.
