How long do grape vines live for?

As grape vines age, their ability to produce fruit will begin to decline at a certain point. Most healthy vines reach the end of their viable, effective lifespan around 25 to 30 years and once a vine gets to this age the clusters of fruit become less dense and much more sparse.

How much to prune?

Spur pruning. Growth of spur and buds during the growing season, and the resulting spur the following season. Images courtesy of Eric Stafne, Mississippi State University.

What is vine balance?

Consequently, the concept of vine balance is the basis of most pruning strategies. In some winegrowing regions, balanced pruning formulas are used to guide growers’ decisions on the number of buds to retain. The bud count is based on an estimate of the weight of extraneous canes removed by pruning –- the pruning weight.

What happens when you prune too few buds?

Excessive pruning –- retaining too few buds -– leads to an undercropping situation. Removal of fruitful buds reduces crop load, but it also eliminates primary shoots. When there are too few shoots in relation to the vine’s growth capacity, the vine compensates for the deficit by increasing the vigor of the remaining shoots, producing more extensive lateral growth, and stimulation of shoot growth from secondary, tertiary, or latent buds. The consequence is often an excessively shaded canopy that provides a poor fruit-ripening environment.

Why are my canes so vigorous?

If some canes were excessively vigorous, that is an indication that the vine’s canopy may have been too large, perhaps because too few buds were retained the previous year. Again, other vineyard circumstances must also be considered, such as having vine spacing too close for the soil type or excessive application of fertilizer. The situation might be remedied by retaining a corresponding number of additional buds to accommodate the excess vigor, if there is adequate space on the trellis. If a crowded canopy is likely to be a problem, another solution will be necessary. One approach is to retain one or more ‘vigor diversion’ or ‘kicker canes’ in addition to the fruiting canes. Shoots are allowed to grow from these canes (diverting the excess vigor) until about bloom time or shortly thereafter; then the entire cane is cut off at its base. Other vineyard management practices should also be considered to reduce excessive vigor, including the use of cover crops.

What is pruning system?

The training system is designed to encourage the production of new fruiting canes at specific positions on the vine – the arms or cordons. Pruning should be done to selectively remove unsuitable or extraneous canes, while retaining a small number of good canes.

How to train grapes?

Cane training of grapes 1 Annually: When the outside cane has borne fruit, cut it back to the inside stub, now holding two or three new canes. Select the best and tie it to the trellis for fruit. Cut the next cane to two or three buds. Remove the weakest at the base. Repeat each year. 2 Third dormant season: Remove shoots from the trunk. Cut horizontal branches back so that two long shoots remain on each. On a two-wire trellis, you can leave up to eight shoots per vine. Tie the shoot farthest from the trunk to the trellis. Cut the other to two to three buds. The tied shoot will fruit the following summer. The clipped shoot will produce growth to replace it the next winter, and fruit the year after.

How do grape spurs work?

Why is it important to let more sunlight reach grapes?

When the grapes are nearing full size, it is important to let more sunlight reach the fruit – this will increase the sugar content and make the bunches more delectable.

How to prune grapes for fruiting?

Fruiting shoots grow from 1-year old dormant buds. Pruning is done to replace the fruiting wood each year. Grape pruning requires removal of between 80 and 90% of the canes each year. A fully mature, healthy vine can support a total maximum of 40 shoots. Younger vines will need to have fewer shoots until they reach maturity. Limiting the number of shoots is important for good cluster size, root balance, and preparation for winter. Grape pruning is done in one of two ways depending on the variety and training system: cane pruning or spur pruning. In general, American type grapes and many hybrids should be cane pruned because their basal buds are typically only vegetative (leaves but no fruit). This means if you are spur pruning them you would be cutting off the buds that are most likely to produce fruit. European grapes can be cane or spur pruned. If you are not sure which pruning method would be better for your variety, it is best to use cane pruning. Each of the two methods are described below.

The best system for your grape vine depends on the cultivar grown, the climate, soil fertility, and personal preference. This fact sheet details two common systems, the 4-cane single-trunk Kniffin system (cane pruned) and bilateral high cordon (spur pruned). Both systems work well for Utah home growers.

How long does a cane last?

In a cane pruned system, the trunk (permanent wood) is kept each year, along with fruiting canes originating from the trunk. After a cane produces fruit for 1 year , the majority of the cane is removed. A new fruiting cane and a renewal spur, both originating close to the trunk, are kept for regrowth of next year’s fruiting cane. Cane pruning is a good option for cold climates. There are many different cane-pruned systems; the 4-cane single-trunk kniffin system described below is relatively simple and has been used successfully in Utah.
