Such fences may obstruct sunlight and interfere with spraying. This system provides good conditions for producing high quality fruit. The fruit and foliage is held well up on the trellis for good sunlight exposure and air circulation. These conditions aid in reducing diseases. The long fruiting canes used make the system best adapted to vigorous varieties or in situations conducive to vigorous growth.
Early training follows the procedure described previously, and the same two-wire trellis is used.
Develop the trunk to a point near the top trellis wire, removing canes that arise near the lower wire or below. Under average conditions this will require two years, but some plants may reach the top wire in one. In the following growing season, shoots will develop from buds along the upper trunk. The growth of these shoots can be improved by early removal of those which develop below. Remove all others.
