Is it dirt yet?
I sheet-mulched in November. Today when I fork off most of the straw, I still see identifiable stuff such as pine straw, hickory hulls, sticks, manure. But I also see LOTS of black worm castings, and each forkful disturbs at least two or three of the most gorgeous earthworms, some 5-8 inches long.
How do I know when it's dirt? Can I plant in this space now? Or should I pull the sheets back up and let it sleep awhile longer?
