Prepare Your Vineyard for Success
Although the busy days of harvest are now behind us, there isn’t much time for vineyard staff to sit back, relax and enjoy the fruits of their labor. Now begins the important task of pruning, and winter is the ideal time to separate healthy wood from the dead and damaged. Whether you’ve just started vineyard operations or have been running a vineyard for decades, it never hurts to be reminded of the best dormant pruning practices and learn about emerging technology to make this vineyard task easier.
The Purpose of Pruning Grapevine pruning shears
Dormant pruning is critical to grape growing because it maintains the training system, allows operators to select fruiting wood, and manipulates the quality of fruit produced. It helps maintain vine form, regulates the position and number of shoots on a vine, improves fruit quality, stabilizes production and improves bud fruitfulness through careful bud placement and selection. Pruning is also an opportunity to get control over weeds, identify vine diseases and address pest concerns before they become significant issues.
When to Prune
As a general rule, dormant pruning can be done anytime between leaf drop in the fall and bud break in the spring. Vineyards around the country may start pruning right after Thanksgiving into mid-December, but this tedious job usually extends through March. Some vineyards wait until January to begin their dormant pruning because this is when the canes become woody.
Jordan Lonborg, viticulturist at Tablas Creek Vineyard in Paso Robles, California, told The Grapevine Magazine that his vineyard chooses when to prune largely based on weather.
“We typically start pruning in January,” he said. “But the majority of pruning takes place in February and March.”
Vineyards may postpone pruning to assess cold injury better and adjust pruning levels to compensate for losses. Double pruning is sometimes used to avoid spring frost injury. However, the availability of labor in the winter months has a big impact on when vineyards do their pruning as well.
Types of Pruning
Grapevine pruning shears most commonly used for grape varieties that have low natural fruitfulness on the basal buds. This type of pruning requires vineyards to replace the one-year-old canes annually.
Spur pruning is most often used for high fruitfulness varieties and is relatively easy to do. This is the most popular method of pruning among vineyards today, particularly for grape varieties like Merlot and Cabernet Sauvignon.
Meanwhile, head training is sometimes practiced by vineyards without trellising. While this practice is economical, it’s important to watch for rot and mildew, as well as congested canopies that can topple under their own weight.
“We spur prune the majority of the vineyard because 65% of the vineyard is on trellis,” said Lonborg. “Ten percent of the vineyard is cane pruned as well. A majority of the cane pruning occurs on Syrah and Viognier due to their vigorous nature.”
Disease Identification and Weeding While Pruning
Grapevine diseases can occur at any time of the year, but the winter season is a useful time to check plants for abnormalities and take action. Some of the most common diseases that grapevines experience are Pierce’s disease, phylloxera, downy mildew, powdery mildew, gray mold, black rot and vine truck diseases such as Petri disease and black measles.
