How to Prune Grape Vines: Cane Pruning

Prune one or two canes on each side of the trunk over the trellis wire to about 12 buds. These 12 buds will become fruiting canes and grow grapes.
Choose one cane on each side of the trunk and prune it to two buds as a renewal spur.
All other wood can be removed.

What happens if you don't prune grape vines?

The disadvantage of not pruning enough is that the plants produce a lot of foliage that becomes shade. This limits the plant's ability to set fruit buds for the following year. So, you have a lot of foliage growth, and then it just becomes a jungle. This is a grape plant that has been properly pruned.

When should I prune my grapes for winter?

- Once grapevines lose their leaves, the plants fade into the background of the winter landscape. That's the time to take action and get out the clippers. January through the first of March is the season to prune your vines, said Bernadine Strik, a berry specialist with Oregon State University Extension Service.

How much should you cut back grapevines?

Grapevines are normally considered to be mature and fully productive in year three. Dormant pruning should be completed starting in late February through March. One-year-old wood (the previous summer's growth) should be pruned back to three to five nodes per spur.

What is the best month to prune grapes?

Grapes are best pruned in spring (February/March, or even as late as early April) because if pruned too early a hard frost in late winter can damage the canes and buds.

Can I prune my grape vine in October?

The main pruning time is early winter (late November or December). Pruning later can cause the vine to bleed sap, weakening the plant. Training and pinching out of new shoots, as well as thinning of fruits, is carried out in spring and summer.

How do you increase grape yield?

Give Grapes a chance to grow and cluster to get more nutrients and water per Grape plant. Remove the lower half of the cluster, leaving four to five side branches near the top. Since these branches grow side by side with the main stem of the cluster, they can bear fruit without crowding.

How do you winterize grapes?

In cold climates, grapevines are generally covered with about 8 inches (20.5 cm.) of mounded soil. Extremely cold regions should also add some insulating mulch such as straw or shredded cornstalks (which are more water-resistant). The addition of snow in these areas provides adequate insulation for protecting vines.

Do you prune grape vines every year?

Because of the way grapevines grow and produce fruit, growers must prune annually. Fruit is only produced on shoots growing from one-year-old canes. Therefore, healthy new canes must be produced every year to maintain annual production of fruit.

Can you prune grape vines in November?

Vines go into winter dormancy in November or December–losing the last of their leaves and leaving only bare cane shoots in their canopies–which is the ideal time for the vines to be pruned of their old wood.

What happens if you prune grape vines too early?

Pruning vines before they are fully dormant could interfere with the ability of the vine to go dormant, thus increasing the potential for cold injury. The earlier vines are pruned in winter, the greater the number of buds that should be left as a hedge against cold injury.

What age can you stop cutting grapes in half?

For kids 12-24+ months, cut each grape in half vertically (or longways), then cut in half to make long quarters. For kids 24-48 months, cut each grape in half vertically (or longways). For kids over age 4, grapes may be served whole but always be sure the kids are sitting down to keep them as safe as possible.

Should I cut the leaves off my grape vine?

If there is too much leaf cover for good air circulation and sunlight, trim off leaves, or remove other shoots if they do not have fruit clusters. If you have excess shoots leaning over the top of your trellis, cut them to be about 6 to 8 inches long.

Should I remove leaves from my grape vine?

Leaf removal has several benefits, from improving grape and thus wine quality to making other vineyard activities much easier, such as enabling good cluster coverage of fungicides, to easier harvest, without all the excessive leaves around the fruits.

Should grapevines be pruned in summer?

While grapes are generally cut back hard in winter, or early spring, to develop their framework, now is the time to treat them gently by cutting back the thin green stems. Proper summer pruning will allow sunlight to penetrate through the leaves to improve the color of the grapes as well as controlling disease.

Do grapes rot faster off the stem?

Do grapes last longer if stored on the stem? Short answer: Yes. Grapes spoil faster once they're plucked off the stem. This is because removing the stem leaves a hole in the grape's skin.

Should grapes be cut into halves or quarters?

Grapes should always be cut lengthwise so they can pass more easily through smaller throats. Never slice widthwise because they'll still be big enough to choke on. You can either slice them downwards in half, or for small babies, you might want to cut them lengthwise again into quarters.

When should I start fertilizing my grapes?

If fertilizing is necessary, apply a small amount of 10-10-10 fertilizer two to three weeks after planting, keeping it one foot away from the vine's base. Increase the amount in the following years before bud swell in the spring. Test the soil periodically (3-5 years) and keep soil pH at 5.0-7.0.

How do you prune vines in the fall?

When you prune, be sure to do the following:

Cut to healthy wood if removing dead, diseased, or damaged growth.
Cut back to a lateral shoot or bud.
Cut to a bud or stem that is pointing in the direction you want the vine to go.
Cut cleanly and don't leave a stub, which is an invitation to bugs and diseases.

Can you prune vines in the fall?

Its best to wait till late fall or early winter to do the pruning. But if some of your plants are being smothered by vine, you may want to tidy it up right nowand a minor bit of cutting is fine. A major pruning at this time would not be good. You could get excessive bleeding (sap dripping from the cuts).
