Secondary trellising

2166. The secondary trellis is placed from 6 in. to 18 in. behind the first, and is used for training shoots of the current year, while that nearest the light is devoted to such as are charged with fruit. In ordinary trellises, the wires are generally placed from 9 in. to 1 ft. asunder, in a horizontal direction; on the secondary trellis they are placed at double that distance.
