rather depends on the wood. Big old poplar is a git to split wet (it doesnt get much easier when dry TBH) but younger poplar splits beautifully either way. Split wood dries faster. In the UK, ideally you log to 25-30cm, split then store. The french are different (quelle surprise, ROdney) and store as 3ft split cords and the log them later. Seems weird to me, but Edukator will probably tell us why it’s done that way.
If you arent going to get a shed built for it this winter, at least get a tarp over it all. You could of course go full mcmonter and log/split and hoffhausen it right away…
