My husband and I have been cutting wood for a bit and have a pretty good pile for next year. This is the tops of trees cut last February and will be stacked for next winters' use. My husband had me get plastic tarps and we covered the stacks. Now we have been wondering if we are not stopping the drying process by covering the stacks. Thinking that keeping the snow and rain off is important but does covering stop the natural drying process. What do you think, cover or not cover?
