The main reason I asked, is that my vines are only in their second year, and were moved to new beds at that. So far my canes have been manageable. Guess I may have to construct some kind of support, maybe by the end of this season or the beginning of next. My plants are in self contained 3 x 3 boxes which are placed on a weed barrier. Perhaps that will keep the plants growing in a more orderly way. So far they are looking great, with moderate sized canes which are loaded with fruit which just started ripening this week.
Eclectic gardening style, drawing from 45 years of interest and experience. Mostly plant in raised beds and containers primarily using intensive gardening techniques.
