Those black spots aren’t fly droppings. Around Delmarva, this time of year means power washing, fresh mulch, and getting homes ready for spring—but many homeowners don’t realize what may actually be causing those stubborn specks on siding, railings, and trim.
It’s often Artillery Fungus—a fungus that grows in mulch and launches sticky spores that can cling to surfaces as high as 15 feet up. They’re tough to remove, and in many cases require hand scrubbing even after power washing.
A recent project led to a smart long-term solution: removing the mulch and replacing it with decorative stone. Cleaner look, lower maintenance, and no more mystery spots.
Spring projects are in full swing across Delmarva.
