Grapes grow on new wood, not old branches. In fact, in an average vineyard, 80-90% of the new growth is pruned off each winter. This may sound drastic, but it is necessary for the health and productivity of the grapevines.
When it comes to grape production, new shoots are where the magic happens. These young shoots are where the grape clusters develop and ripen. The older branches, on the other hand, tend to become less vigorous and produce fewer grapes over time. By pruning off the old wood, we encourage the vine to put its energy into producing new growth, which in turn leads to a more abundant harvest.
Pruning the grapevines in winter is a common practice among grape growers. It not only helps control the size and shape of the vineyard but also ensures that the energy of the plant is directed towards the most productive parts. By removing the excess growth, we allow the sunlight and air to reach the remaining shoots, promoting better photosynthesis and reducing the risk of diseases.
I have personally experienced the importance of pruning in grape cultivation. In my own vineyard, I have witnessed the difference between properly pruned vines and those that have been neglected. The pruned vines consistently produce healthier and larger grape clusters, while the unpruned ones tend to have smaller, less flavorful grapes.
Pruning is typically done during the dormant season, when the grapevines are not actively growing. This is usually in late winter or early spring, before the buds start to break. It is crucial to prune at the right time to avoid damaging the vine and to give it enough time to recover before the growing season begins.
There are different pruning techniques used in grape cultivation, depending on the specific variety and training system employed. Some common methods include cane pruning, where a selected number of canes are left to bear fruit, and spur pruning, where spurs are retained on the cordons to produce new shoots. The choice of pruning method depends on factors such as vine age, growth habit, and desired vineyard management goals.
Grapes grow on new wood, not old branches. Pruning plays a vital role in maintaining the health and productivity of grapevines. By removing the majority of the new growth each winter, we ensure that the vine’s energy is focused on producing new shoots and grape clusters. Proper pruning techniques and timing are essential for maximizing grape production and maintaining the overall health of the vineyard.
