Loving all the advice gents. I have restacked most of the wood by now and have paid much closer attention to the ends as well as making sure the splits are relatively level. I've used some shims to achieve this and I have reduced the height of the stacks. I think that a large part of the failure was due to thawing soggy ground. They say that ash has a relatively lowers moisture than most other woods. Is stacking in rows of three for 8 monthes going to work for seasoning? Or should I go with single rows?
