How to Prune Grapevines for Sweet and Juicy Grapes

Grapevines can be a bit intimidating to prune, but with the right techniques, you'll be able to grow grapes that are sweet, juicy, and bursting with flavor. In this blog, we'll cover everything you need to know about pruning grapevines, including the timing, terminology, and tools you'll need to get started.

Timing is Key

The timing of pruning your grapevines is crucial. In California, grapevines are typically pruned in January or February, although some growers do it in December. The key is to wait until the grapevines have gone dormant and all of the leaves have fallen off. This makes it easier to see the canes and make informed decisions about which ones to keep and which ones to cut away.

Two Main Techniques

There are two main techniques for pruning grapevines: cane pruning and spur pruning. In this blog, we'll focus on cane pruning, which is the technique used for newly planted grapevines.

Terminology and Tools

Before we get started, it's important to understand the terminology used when pruning grapevines. The trunk of the grapevine is the main stem, the cordons are branches that grow horizontally along the ground, the cane is any new growth coming out of the plant, and the bud is a small nub from which new canes will grow.

It's also important to use clean pruning shears when pruning your grapevines. This will help prevent the introduction of disease into your plants.

Cane Pruning

To begin cane pruning, select two upright canes that are in good shape. Remove any canes that are growing off of the main trunk, and tip the two selected canes to prevent them from growing into each other. Remove the rest of the cane, leaving behind the newly pruned cane. Wrap the cane around a steel wire or stake to train it to grow in the desired direction.

Final Thoughts

Pruning your grapevines may seem intimidating at first, but with the right techniques and tools, you can grow grapes that are sweet, juicy, and bursting with flavor. Make sure to follow the tips and tricks outlined in this blog, and you'll be on your way to growing the best grapes you've ever tasted!
