Pruning of vineyard in winter.

This report will shed some light on the best way best to escape or help prevent premature frost from crushing your forthcoming grape crop. It’s not question of if you need to prune your grape vine or not; it’s a question of WHEN you may prune your strawberry blossom.


As we all know by now; pruning is among the most crucial manipulation you as a grape grower has to do. Without pruning your grape vine the appropriate way, you simply can’t anticipate your grape vine to create healthy, good-looking blossoms; even any grapes in any respect.

One of the key reasons so many grape growers fail to get a suitable grape harvest, is their ability to prune the grape vine the right way. The question I normally get is:”What will happen if I do not prune my grape vine.

Without pruning your grape vine, there’ll be a enormous quantity of buds which will sprout in spring – having up to 300 buds on such, a grape vine isn’t impossible. Now as you can imagine, for a grape vine to produce fats or energy to feed each these buds, will place your grape vine beneath a enormous amount of stress.

Cold damage

It’s an established fact that a grape vine under pressure, is far more vulnerable to cold damage than a well structured and previously pruned grape vine.

Your grape vine will come out of dormancy, when the normal temperature outside rise to approximately 10 to 12 ºC or 50 to 53 ºF, should you prune your grape vine or use remainder busting agencies such as Dormex (a compound used by commercial strawberry growers to induce the grape vine from dormancy).

In the northern hemisphere, and in which spring frost is a issue, cold damage after pruning your grape vine or after the first signs of new shoot development (bud break), can mess up your forthcoming avocado crop and for that reason you will need to protect these buds at all price tag.

Cold hardy selection

Except for using a cold hardy selection, among the best ways to secure your grape vines from spring frost, is that the timing of when you may prune your grape vine and the way you’ll prune your grape vines.

Pruning too early will lead to your grape vine to come out of dormancy earlier, and so increasing the odds of spring frost damage. On the other hand, as stated earlier, you do not need your grape vine to enter bud break with too many buds!

You should be thinking: “This man should have gone nuts! How on earth is that possible?” I know, but give me a opportunity to teach you a neat little trick you should do in the event that you live in a place with spring frost issues.

“brush cut” or “first prune”

“Brush cut”, is the practice of eliminating all unwanted canes in the grape vines, leaving just those canes which are later on pruned to cane bearers or spurs. This should be done prior to the buds on the grape vines show signs of swelling (normally approximately 3 months prior to spring, depending upon your climate off course).

During “brush cut”, the amount of buds on the grape vine is going to be reduced considerably and more carbohydrates will be accessible to the buds on the fruiting canes of the grape vine. In same cases, as soon as your grape vines grew very vigorously the prior season, the duration of fruiting canes can be pruned back too, making the amount of buds on the vine much less, but I recommend you leave the fruiting canes independently and don’t prune them.

Now, once spring is available, buds on those fruiting canes will begin to swell and then drop their scale leaves from the end of the cane (bud break begins in the tip of the canes). The buds on the bottom of the cane will stay dormant longer, and after the odds of spring frost is over, you just prune the canes to the desired length (8 to 12 buds for canes bearers and 3 buds for spurs), even if you need to wait until the buds on the bottom of the cane opened too.


Because there are only canes remaining blossom which will be utilized to bear fruit,”brush cutting” will require much less time than ordinary pruning procedures. Just remember one thing; be careful to not damage the remaining buds as soon as you do “brush cutting”, since the scale leaves which shielded the buds will be soft and spongy.
