It’s finally spring and that means that soon there will be an explosion in our gardens and yards. I can’t wait! When I survey my lawn (yes, I still have lawn), I can see patches that will need some attention: especially raking and overseeding. I’m hoping that the skunks don’t come to visit this year, which indicates the presence of white grubs.
What I cannot see yet, but know that they’re going to appear in some of the wetter areas: mushrooms. Mushrooms popping up in your lawn in the spring is actually pretty normal and usually nothing to worry about. Here’s what’s going on:
Why they grow:
- Moisture: Spring brings rain and warming temps—perfect conditions for fungi to grow.
- Organic matter: Mushrooms feed on decaying stuff underground like old tree roots, buried wood, mulch, or even thatch in your lawn.
- Healthy soil: Ironically, mushrooms can be a sign your soil is rich in organic material and biologically active.

Are they bad?
- For your lawn? Nope! Mushrooms don’t harm the grass. They’re just the fruiting bodies of underground fungi doing their natural recycling job.
- For pets/kids? Some wild mushrooms can be toxic if eaten, so it’s wise to remove them if you have curious little ones or pets around.
Can you stop them?
You can’t totally prevent mushrooms, but you can reduce them:
- Improve drainage (mushrooms love dampness).
- Rake up thatch and remove any rotting wood or roots.
- Don’t overwater.
- Mow regularly to knock them down.
In summary, mushrooms in a lawn are generally not harmful and can even be beneficial, as they help break down organic matter and release nutrients into the soil.
