I recently planted several hybrid grapes: Marquette, Petite Pearl, and Verona. I'm located in SW Idaho where vinifera grapes do well in general. Most of the commercial vineyards in the area use the mid-wire cordon or VSP trellis systems. Being a backyard grower and with the research I've done so far, hybrids tend to be downward growing vines, so high wire double cordon trellis system would be most appropriate. However, I'm a bit concerned about too much sun exposure to the grapes with HWC since summers can be quite hot in this region. Can anyone verify if the HWC system would be a better trellis system for this region, or should I use an upward growth system like VSP for these hybrids?
