vine starts every spring with but a single cane. [Illustration: 35. HORIZONTAL TRAINING.] Excellent results are obtained from the slender growing varieties by this method of training, but it is too expensive in trellis and in labor of tying to make it generally practicable. Delaware, however, thrives remarkably well when trained in this fashion. _Post Training._--There are various methods of training to posts, all of which possess two advantages--the saving of the expense of trellis and allowing of cultivation both ways. But they also have grave disadvantages, especially in the thickness of the head of foliage which harbors rot and mildew and prevents successful spraying, and hinders the fruit from coloring and ripening well. These faults are so serious that post training is now little used for the American grapes. The saving in cost of trellis is not great, for more posts are required to the acre than in the trellis systems, and they do not endure long when standing alone with the whole weight of the vines thrown upon them. [Illustration: 36. LOW POST TRAINING.] There are various methods of pruning for the stake training, but nearly all of them agree in pruning to side spurs upon a permanent upright arm which stands the full height of the vine. There may be one or two sets of these spurs. We might suppose the Kniffin vine, shown in fig. 22, to be tied to a post instead of stretched on a trellis; in that event, the four canes would hang at will, or they might be wrapped about the post, the shoots hanging out unsupported in all directions. The post systems are essentially Kniffin in principle, for the shoots hang free. In low styles of post training, the permanent head of the vine may be only three or four feet high. This head will have a ring of spurs on it, and at the annual pruning three to five canes with from six to ten buds each are left. Fig. 36 is a view in such a post vineyard.
