Cane pruning – system of cutting the vine back to one or more canes that will produce new shoots. The aboveground portion of a cane-pruned vine will have a trunk, one or more canes on which shoots will develop from buds on canes and renewal spurs to be used as sites for new canes for future fruiting sites.
Herein, what is a grape vine cane?
Canes are the one- or two-year-old branches of the grape plant. They grow as shoots off the main trunk. Vine growers train them to grow horizontally along wire trellises. It is from buds on these canes that the leaves and fruit of the grapevine grow.
Also Know, is cane pruning more difficult than spur pruning? In general, one should leave 3 buds if the spur is thumb-size in diameter, 2 buds if the spur is the size of a middle finger and 1 bud if the spur is pinkie-size. Cane-pruned varieties, such as Thompson Seedless, are always more difficult and expensive to prune because great care must be taken in selecting wood.
