Need some help after experiment in zone 6
I am actually in Cleveland Ohio and tried various cold hardy varieties listed for zone 6. I have had mixed results. Those spring blooming hardy types that I wraped or covered with a piece of burlap seem to be fine and buds are quite healthy looking. The fall bloomers, that I planted, and didnt cover or wrap, assuming they were slightly hardier, are burned and or defoliated. (Lesson learned to cover) That said, the stem tissue is still green on all plants. Can a camellia recover from defoliation in the manner in which a holly or magnolia grandiflora can? Thank you for your help!
