I harvested some this past spring and it does check easy. Someone on here had a post about wrapping it in plastic for a month or so. I tried that and it helped. Just a nearly sealed wrap to allow slow moisture drop and also sealed ends. Bark still cleaned up easy afterwards and there were no checks.
One accidental thing I thought was really interesting; I cleaned up the back of one 2" stick, sealed the back with shellac, and left the other side of it with bark on. Even after over a month in the plastic it pretty quickly developed checks the length of the stick and they were almost exactly along the line of the remaining bark
It halfway split itself
. I eventually roughed it down to bow shape and it is still a good stave in waiting. Good luck with it. Marco
