Q.Camellia Plant Has Lost Its Leaves
My camellia was a healthy plant of five years old until the end of this winter when we had a bout of severe frost after an apparent thaw. I’ve tried feeding but leaves are just going brown and hardening before falling off. Also, it has a green moss type covering on its branches andĀ appears to be dying. Is there anything I can do to save the plant?
