The Cordon or Wall System of Growing Grapes
There are those who have tried out the Labruscan varieties from Ontario. These cannot be grown under Guyot pruning methods but must be cultivated by a simpler system such as one main rod plus six strong side growths, which are pruned back hard each January.
In the spring choose the stoutest and strongest growth and tie this perpendicularly to a stake. Cut out all other growths and concentrate on this one. Do not carry out any summer pruning, just let this strong rod develop naturally. Next January cut this rod back to within 3 buds of its base. When the 3 buds grow out, keep them, tying them to stakes or bamboos so as to form a goblet shape. Do not do any summer pruning.
Once again in January cut back these 3 canes to within two buds of their base. Thus you will see that you are now producing your goblet-shaped bush with 6 branches. Each one of these 6 branches may carry six or seven bunches of grapes and the following January again they will be cut back to within two buds.
Red Spiders can be detected by examining the back of the leaf with a magnifying glass. Red Spider is a bad name. Yellow Mite would be better.
Each of these laterals is allowed to bear one bunch of fruit this season. As the cordon is to remain tied horizontally to the lower wire, these laterals are pruned back in January to within one plump bud of their base. This bud, of course, will grow the next spring and once again the lateral will be trained upwards and tied to the top wire. This next year it will probably bear two good bunches and the year after maybe three bunches. From then on the crop will be three or four bunches per lateral.
Those who don’t believe in straw mulching may like to know that the prunings and foliage of healthy vines may be roto-tilled shallowly into the soil, in November, and so help to keep up the humus content. By rotary hoeing you smash up the prunings which then soon decompose.
