I looked for your other post, but, being computer stupid, I couldn't find it! So ,was this a "first year" plant? I would guess that the split is the result of a well watered, large , rhisome, freezing. Just a guess. The "dead' tisssue seems to be in the center, or "growing point" of the fan, which is how they described "scorch" in posts last year. But I don't think thats an early season problem. So my best guess is that the plant was exposed to very cold temps after it had broken dormancy and started growth, damaging the " core' of the fan. If it was mine , I'd keep it as dry as possible( put a "tent" over it before rains, or even dig, and pot it, so you can control moisture) Good luck, and keep us posted....Arlyn
