I'd like to define "seasoned" and "dry" wood. I think of seasoned wood as wood that has lost as much of it's interior moisture as possible. Typically well seasoned wood would be at least an entire summers worth of drying in good sun and breezes in cut and split condition. Two years would be more reliably and thoroughly "seasoned". Dry in my mind defines whether the wood surface is wet or not. In other words, it would be possible to have dry but not well seasoned wood (not good stove fuel!) as well as seasoned but wet wood. It is my experience that drying wet but seasoned wood does not take long at all, perhaps as little as a couple of days in good conditions. Therefore, the goal of all of us wood burners is to properly "season" our wood. For anybody using wood as fuel, I believe the only really reliable way to do this well, is to always be working at least a year ahead on your wood supply so that it has a chance to truly "season".
