I've not had problems with my plant until this year. We had a wind storm in June that ripped shingles from the house and blew all kinds of things around, including my daughter's heavy plastic playhouse into the lake. The growth tips from the mature plant along with the first year plants were all ripped off. They all survived, and the mature plant still produced three oz. of dried cones. A "good breeze" wont' hurt hops, it'll probably help prevent mold.
