Two previous planted arborvitae died over the winter. . . same spot, two successive winters. I have bought a new one from Home Depot. Rather than plant again, I would like to keep it in its container and put it on the deck. Is the potting mix of commercial container OK to leave as is? It seems to look healthy as is. Should I fertilize and store in garage over winter?
