>>2702706>So will this log grow roots anywhereNope, roots may grow only from exposed cambium layer. That is, roots can only form in a thin layer between bark and wood exposed by the cut, as well as from buds (including dormant buds, that reach the verge of the bark and might be barely noticeable).
Bark is simply dead, wood cannot create new cells, phloem can at best produce more phloem.
