What is the difference between cane and spur pruning?

What are the key differences between cane and spur pruning? Spur-pruned vines have the look you might expect from grapevines. It is from those spurs that we get new vine growth each season. Cane-pruned vines, on the other hand, are not trained in a “T” shape.

When should a cane be pruned?

The first year’s canes (Primocanes) are vigorous and are best left unpruned or tip prune in winter to a suitable length (approx. 1.5m). In the second year these canes are now called floricanes and produce short laterals in spring on which the flowers and fruit are borne.

What are the main aims of cane pruning?

Cane Pruning The aim of this type of pruning is to leave a small number of canes with multiple buds. The canes grow from the top of the trunk of the vine. This method should also be used on varieties that don’t have flowers in buds in the lower parts of the cane – for example the sultana variety.

Are Concord grapes spur pruned or cane-pruned?

All grapes require heavy pruning to produce fruit, but after the first three growing seasons, different types of grapes need different methods of pruning. Wine grapes and muscadines usually need spur pruning, and American grapes, such as Concord and Thompson Seedless, require cane pruning.

What is the difference between a shoot and a cane?

Because a cane is simply a mature shoot, the same terms are used to describe its parts. Pruning severity is often described in terms of the number of buds retained per vine or bud count. This refers to the dormant buds, which in a single bud contains three growing points as described above.

What is the difference between a cane and a cordon?

Cane pruning requires an annual replacement or renewal of one year old wood (canes) on the fruiting wire. Cordon pruning leaves a permanent horizontal extension of the trunk in place year after year. Cordons can be decades old and achieve diameters of several inches or more.

What is a cane shrub?

What are cane-growing shrubs? Cane-growing shrubs grow from multiple stems rather than a single branched trunk like some shrubs. These plants reach their mature size within a few years and have a graceful, arching habit that sits beautifully in any landscape.

What is cane pruning of grapevines?

Cane pruning – system of cutting the vine back to one or more canes that will produce new shoots. The aboveground portion of a cane-pruned vine will have a trunk, one or more canes on which shoots will develop from buds on canes and renewal spurs to be used as sites for new canes for future fruiting sites.

What is the cane of a grape vine?

Canes are the one- or two-year-old branches of the grape plant. They grow as shoots off the main trunk. Vine growers train them to grow horizontally along wire trellises. It is from buds on these canes that the leaves and fruit of the grapevine grow.

What’s the best way to prune fruiting canes?

The first step in pruning is to identify the fruiting canes for next year. Desirable fruiting canes develop under conditions of good sunlight exposure, which is a function of the training system, last season’s pruning level, and canopy management practices. Good sunlight exposure promotes bud fertility and wood maturity.

What’s the difference between cane and spur pruning?

Illustrated below is the process of pruning canes, creating new two-bud spurs and pruning the remaining new growth to form replacement laterals. Once again, there is a repeating pattern which makes it easier to understand, but cane pruning is a bit more complicated than spur pruning. Continuing into the sixth year, the pruning remains the same.

When do you pick new canes from the vine?

The buds below the pruning cut will shoot during the growing season to produce new canes. In the cane pruning system, a permanent trunk is established, but the lateral canes are renewed every year. New canes are selected from the head of the vine, at the top of the trunk near the trellis wires.

How to prune grape vines with canes and spurs?

To establish the first set of lateral canes: 1 Select one or two canes on either side of the trunk, prune them each to 8-12 buds long (up to 16 for some varieties),… 2 Select one spur canes on either side of the trunk and prune back to a two-bud spur. These renewal spurs provide… 3 Prune off all other growth. More
