I am in zone 5 / 6 and plan to grow a rosemary ‘Madeline Hill’ in a large 24" pot this summer. It’s hardy in my zone, but I’m in a hollow that gets winter winds, so I want to overwinter it in my unheated garage in its pot. Everything I read on wintering rosemary says it has to be brought indoors in a sunny window … but that’s for the non-hardy kind, right? Will I be able to keep this zone-5 rated rosemary in my garage? Will it need light and water all winter or does it go dormant like other cold climate shrubs? I’ve checked other forums (fora?) and no one seems to have experience keeping rosemary in 35 – 45 degrees over winter. Have you or others done it? Thanks for any help on this!
