Calls have been coming into our office with homeowner’s wanting to know why they have mushrooms in their lawn. Mushrooms come from a mixture of moisture (we’ve had a good amount of rain lately), cloudy weather, and organic material such as old mulch, animal waste, or rotting tree stumps.
Mushrooms are the reproductive part of fungi that lives in the soil. Not only are mushrooms an eyesore to your healthy lawn but you don’t want children or pets to have access to them.
You can get rid of the mushrooms by manually removing them from your yard but that still does not take care of the problem. Chances are the mushrooms will return. Mushrooms will often go away when the sun comes out and the soil dries up.
There are preventative measures that you can take to prevent mushrooms from showing up in your lawn:
- Decrease shade – Mushrooms like shade so trim back any branches in problem areas. The more sunshine, the less likely you will see mushrooms.
- Decrease moisture – Moisture in lawns enable mushrooms to thrive. If you have standing water your soil may be compacted and you may need to aerate your lawn.
- Dethatch your lawn – Excess thatch in the lawn absorbs moisture and enables mushrooms to grow.
- Tree Stumps – A place where a tree used to be, even if the stump is removed, can be a breeding place for mushrooms. The dead roots underground can be a cause for mushroom growth. Keep the area aerated and clear (raking helps).
- Pet waste – Remove any pet waste on the lawn on a regular basis.
If you have mushrooms in your yard it is best to call a professional lawn care company to diagnose the problem. Mushrooms can sometimes be a sign of a more serious problem with your lawn.
