A fter planting your vine, it should be cut back in December to some nice fat buds. In spring, when new shoots grow, tie them up vertically to a support. This upright growth will encourage vigour. If sideshoots grow from these main shoots, pinch these out after one leaf. When shoots are vertical they’ll grow strongly but this suppresses the formation of growth buds along the base of the stem. So, in the next winter of this first year pull these shoots down to near horizontal, trim off the end if necessary, and tie them to encourage sideshoots all along the rod.
