Was it leafed out when you worked it?
(Reread sounds no)
I reckon the work may have moved it along too fast.
I gotta new crab from a friend last end of summer. Had some, I reckon wooly adgelid (sp) so I cut it late. That made it come out earlier than everything else, susceptible to frost.
Work tends to start processes that wouldn't have otherwise started. This leaves them in a "confused" state that I consider more dangerous than frost damage, because it's not cut and dry, clearly visible. Worse, it gives us a fake spring, which can go on to kill the rest of our collection.
Best to wait till they put whole leaves out before working them. But not if last year's late work made them come out early.
Don't work late. Don't work early!
I repotted my other crab in summer to no ill effect. Summer is safer.
