The Training System
Most of the cultivars we have chosen to grown have a natural tendency to grow downward (procumbant). Downward growth is known to devigorate the vines. The "high wire" training/trellis will allow for downward growth with the fruiting zone near the top wire.
Our first year of growth we have been focusing on maximizing leaf area for increased root system. For that reason we have kept multiple shoots growing, vs. choosing one shoot to grow for the future trunk. When it comes time to prune in late winter/early spring of year 2, we will prune to two shoots/trunks. We will then focus on establishing the cordon.
