With all the rain we’ve had across Arkansas — and more in the forecast — our office is getting LOTS of calls about unusual fungal growths and slime molds appearing in lawns and landscape beds.
Here are three common things we’re seeing right now:
Slime Mold (“Dog Vomit” Slime Mold)
This bright yellow, orange, tan, or gray growth may suddenly appear on mulch, grass, or other organic matter. While it looks alarming, slime mold is generally harmless to plants and usually disappears once conditions dry out.
Gray Fuzzy Growth on Grass Blades
Some lawns are developing a gray, ash-like or fuzzy coating on grass blades. This is often a turfgrass slime mold that thrives during long periods of wet, humid weather. It usually does not damage the lawn and can often be removed by mowing, raking, or spraying with water.
Fairy Rings
Fairy rings are circular patterns of mushrooms or dark green grass caused by fungi growing underground. Wet weather makes these fungal rings more noticeable. Most are mainly cosmetic, although some may create dry spots in turf over time.
Most of these issues are temporary and improve as soils dry out.
Good airflow and avoiding overwatering can help reduce fungal growth.
In most cases, fungicides are not necessary.
The recent rains have created perfect conditions for fungi and slime molds to thrive, so don’t be surprised if you see some unusual things popping up in your lawn over the next few weeks!
