FIG. 68. Unpruned grapevine trained by the 6-arm 

 renewal system. 



trellis is commonly used for such varieties as 

 the Delaware, plants set seven feet apart, and 

 the vines spread out. Whenever possible, 

 have the arbors or trellis run north and south. 

 Pruning should always be done early in the 

 spring before the sap flows. Cut back the 

 previous year's growth (Fig. 68), leaving two 

 or three buds for new canes. (Fig. 69.)
