I mixed up some soil last spring with a bunch of meals, eathworm castings, etc... I was using Jerrys no till method and have the soil in 20 gallon containers but I have left them outside. I am in MI so it has been frozen most of the winter. My question is will this soil still be good to use if I bring it inside?
well...soil freezes in your yard every year...do plants still grow in your yard<waiting for it to click...>
The soil microbiology is still there, just dormant. Start rehydrating those dry pots about a month before you want to use them. I'd hit them with plain water first, soaking the pot thoroughly and evenly. Then water with a little fish hydrolysate/molasses the next time it dries out.
