Why does nobody warn you that bagged potting mix can harbor fungus gnat larvae
Bought two bags of Miracle-Gro from the Ace on Vernon Ave back in March and within 10 days my whole windowsill of pothos and one sad fern was crawling with gnats. I figured it was just spring, but a guy at the local garden club said the mix was probably already infested when I opened it, and sure enough the third bag from a different store was clean. Now I spread the mix on a tarp and let it dry out for 3 days before using it, which has worked so far. Anyone else have a go-to way to check a new bag before it touches your plants?
