Growing Grape Tips

Although American grapes can similarly be grown on arbors, they are best trained by the four-cane Kniffen system. In this system the vine is pruned to four canes, each of which is tied to a wire. The four-cane Kniffen system can also be used to train some of the European grape varieties, such as Black Monukka, Blackrose, Emperor, Olivette Blanche, Red Malaga, Thompson Seedless and White Malaga. Usually, however, European grapes are better when grown on a single wire strung between posts about 3 to 3 1/2 feet from the ground.

The smooth-skin characteristic that distinguishes nectarines is a minor genetic variation, like red hair among people; it is even possible that a peach tree may suddenly produce a branch that bears nectarines, and vice versa.

A type of pruning that is especially suited to such European varieties as Black Monukka, Blackrose, Cardinal, Emperor, Muscat, Pearl of Csaba, Red Malaga, Ribier, Tokay and White Malaga, as well, as most wine grapes, is called spur pruning. Each vine is grown against a single stake, and each year the growth of the current season is cut back to two or three buds. In parts of the Southwest where there is a deficiency of zinc in the soil, daub each cut with a zinc-sulfate solution, 1 pound to a gallon of water, within two hours after pruning.

For most home gardeners the standard tree is the best one to buy because it is the least expensive, its size can be easily limited to 7 to 10 feet by conscientious pruning and it bears the greatest amount of fruit for the space it occupies. The flowers appear before the leaves come out in spring, and range in color from pale pink to dark red. The fruit generally ripens in midsummer.

Except for muscadine varieties, whose fruit are shaken from the vines onto a cloth, grapes should be harvested by cutting off entire bunches with small hand shears. For best flavor in dessert grapes and for making grape juice or wine, allow the fruit to attain full ripe color on the vine. For jelly making, pick them when they are a bit underripe because they have a higher pectin content at that time and produce crystal-clear jelly. Fresh grapes stored dry in a refrigerator will keep for one to two months.

Most recommended varieties have red-and-yellow skins; the colors pertain to the flesh of the fruits. Peaches are usually classified as clingstones, with flesh that clings to the pit; freestones, with flesh that separates easily from the pit; and semiclingstones, with flesh that clings to the pit before fully ripening, then is generally free.
