Three years of fighting patio moss finally solved by one cheap thing
I live near Portland and my back patio gets zero direct sun, so for 3 years I battled green slime every spring. I tried bleach, power washing, even a fancy sealer. Last week I finally bought a $12 bottle of granular moss killer from the hardware store, sprinkled it on, and within 2 days the moss turned black and just brushed off. Has anyone else had good luck with the simple stuff over the heavy duty treatments?
