The Cordon or Wall System of Growing Grapes
The strong-growing varieties can be grown as cordons if the site is warm and the soil good. The rows have to be 6 feet apart and the cordons 10 feet apart in the rows. The cordons are trained horizontally and thus stakes and wiring must be provided. Under this system a stake with a minimum diameter of 3 inches, and preferably chestnut, should, when 2 feet of its base has been thoroughly treated with Cuprinol, be driven into the ground securely so that the top is 2 feet 3 inches above soil level.
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 the vine is allowed to grow naturally the first year and then it is cut down to within two buds of its base. The strongest of the shoots that result is kept and is tied perpendicularly to a stout bamboo cane. All side growths that develop are pinched out with the thumb and forefinger to their base. When all the leaves have fallen, the long cane should first of all be tied to the stake and then should be carefully bent so that it can be tied along the lower wire. This bending of the cane, at an angle of 90 degrees, is important because the flow of sap is checked.
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.
Some people give each vine one stake, 4 feet out of the ground, and then, instead of tying the rods out to 'form a goblet, they merely tie the tips of the rods to the top of the stakes to form an inverted cone. By the way, do not allow the young cane to go on growing after the requisite number of bunches of grapes have been produced. You should always pinch out the growing point at 3 leaves beyond the top hunch.
When growing a vine against a wall the pruning may be similar. The rod instead of being taken along a lower wire can be trained, with a main rod growing upwards and with side permanent rods trained out at right angles. Thus a series of horizontal cordons are formed and the laterals they produce are pruned back hard each January. These are tied to wires stretched tightly in between the main wires. - 2368
