Protecting zone 5 plants in zone 4
Hi,I just planted a couple of plants that I later found out are suitable for zone 5. They're native plants: cardinal flower and "green and gold". I'm wondering if it would work to just mulch them heavily over the winter then peel the mulch back in the spring. Does anyone know whether this would work? Or would it hurt the plants to have all that mulch on them over the winter?Thanks!JillSee More
