Well here is my delema. I am in zone 9, and I know that a lot of my passies will do fine through the winter, but since I am trying to keep them controlled, would it be wise to cut them back? I have a small yard and porch, and since the vines flower on new growth, I really need to get them back down in size. Some of my passies I know will do fine after cutting, but some of my new varieties I am unsure about. The ones I am really concerned about are: Passiflora Reflexiflora, Sunburst, Alata and Exoniensis. Has anyone had bad luck cutting any of these? Anyone have bad luck with cutting down other varieties? I know some Passies are more finicky. Thanks in advance!
