In the next two weeks I will be taking down approximately 7 trees in total. A combination of shagbark hickory and maple trees. They'll be cut to 12 inch lengths and left in rounds. How long should I wait and is there a best time of year to split and stack them? I figure I should be able able to use the maple next winter 2015-16, and the hickory maybe the following year. I know some prefer splitting in the dry cold, but what your suggestions?
