I've got a pile of fresh split oak the pile is 40 feet long about 12 to 15 feet wide and about 7 feet tall.The trees were felled a year ago and now all is split,I will not be able to get it stacked this year,so I was thinking about covering the top and halfway down the sides with black plastic until I can get it all stacked spring of 2017. Provided we're still here?Will I suffer any varying degrees of rot within the center of this very large pile. The area is partially shaded . Thanks
