Harvest is an extremely busy and exciting time in every vineyard. This is when we collect the fruits of our year-long labor. The keyword there is that our labor happens all year long. In order to set up next year’s harvest for success, we must prune the vines in the dead of winter.
Pruning takes place during the dormant months of the vines; December, January, and February when the vines will not bleed excessively when the cane is cut off. Pruning vines is similar to pruning roses, cutting off the past year’s growth in order for the vine to grow new shoots to develop an appropriate canopy and fruit.
There is more to pruning wine grape vines then simply cutting off old growth. We are also “training” the vine in the shape of a “Y.” This will provide balance, maximum energy flow, and strength to the vine.
The pruning process is done by selecting two of last year’s shoots to be the current year’s fruiting cane. These two shoots make up the top part of the “Y”; the stock is the bottom. The right shoots must be kept to provide the optimal energy flow through the vine and into the fruit. The fruiting cane is that from which the new shoots grow that develop the fruit.
Not only are we pruning for the current year’s crop, we are also pruning to leave spurs for the next year as well. In doing so, we are continuing to train the shape of the vine as it grows from year to year.
Pruning is the way we get a jump on next year’s harvest. What do you do each year to get your next year started out right? Let us know in the comments below.
