I'm looking for advice on how to prepare my trees (they are columnar poplar) and my shrubs (mint junipers) for the winter. I had just planted them this spring (in May). I read that we may be getting frost this weekend and thought I would get on this to ensure they survive this winter. One person I was talking to suggested I wrap them in burlap to keep them insulated for the winter and have a steel stake beside the trees to have them supported in high winds. Thoughts?
