I have one of these that I received bare root and in poor condition from a vendor. It has seemed healthy, then on the verge of dying, then made a come back. It is growing roots like crazy now and a new growth so I am encouraged. I have heard that dens need a winter rest. How severe a rest in the watering process should they get? Does this apply to young dens as well, as I have several babies. I have heard that I shouldn't water at all for several months. Is this right? Any help would be greatly appreciated!
