Of the aestivalis class I can recommend the Cynthiana and the
Herbemont, or Warren, for the extreme South. Both of them are black.
There are new varieties of this vigorous species which promise well.
The cordifolia species promises to furnish some fine, hardy, and productive grapes, of which the Amber is an example. The Elvira, a pale yellow grape, is highly praised by Mr. Hussman. Although the Bacchus is distinctively a wine grape, I have already said that its flavor, when fully ripe, was agreeable to me. The only difficulty in growing it is to keep the ground poor, and use the pruning-knife freely.
I have enlarged on this point, for I wish to direct the mind of the reader to the fact that there are many very hardy grapes. I congratulate those who, with the taste of a connoisseur, have merely to sample until they find just the varieties that suit them, and then to plant these kinds in their genial soil and favored locality.
At the same time I should like to prevent others from worrying along with unsatisfactory varieties, or from reaching the conclusion that they can not grow grapes in their region or garden. Let them rather admit that they can not raise some kinds, but may others. If a variety were persistently diseased, feeble, and unproductive under good treatment, I should root it out rather than continue to nurse and coddle it.
When mildew and grape-rot first appear, the evil can often be remedied in part by dusting the vines with sulphur, and continuing the process until the disease is cured, if it ever is. I have never had occasion to do this, and will not do it. A variety that often requires such nursing in this favored locality should be discarded.
There is one kind of disease, or feebleness rather, to which we are subject everywhere, and from which few varieties are exempt. It is the same kind of weakness which would be developed in a fine sound horse if we drove him until he dropped down every time we took him out. Cultivated vines are so far removed from their natural conditions that they will often bear themselves to death, like a peach-tree. To permit this is a true instance of avarice overreaching itself; or the evil may result from ignorance or neglect. Close pruning in autumn and thinning out the crowding clusters soon after they have formed is the remedy. If a vine had been so enfeebled, I should cut it back rigorously, feed it well, and permit it to bear very little fruit, if any, for a year.
Of insect enemies we have the phylloxera of bad eminence, which has so dismayed Europe. The man who could discover and patent an adequate remedy in France might soon rival a Rothschild in his wealth. The remedy abroad is also ours—to plant varieties which are phylloxera-proof, or nearly so. Fortunately we have many which defy this pestiferous little root-louse, and European vine-growers have been importing them by the million. They are still used chiefly as stocks on which to graft varieties of the vinifera species. In California, grapes of the vinifera or European species are generally cultivated; but the phylloxera is at its destructive work among them. The wine-grapes of the future throughout the world may be developed from the hardy cestivalis and cordifolia classes. In many localities, even in this new land, varieties like the Delaware succumb to this scourge of foreign vineyards.
The aphis, or plant-louse, sometimes attacks the young, tender shoots of the vine. The moment they appear, take off the shoot, and crush it on a board with the foot. Leaf-rollers, the grape-vine sphinx, and caterpillars in general must be caught by hand and killed. Usually they are not very numerous. The horrid little rose-chafers or rose-bugs are sometimes very destructive. Our best course is to take a basin of water and jar them off into it—they fall readily—and then scald them to death. We may discover lady-bugs—small red or yellow and black beetles—among our vines, and many persons, I fear, will destroy them with the rest. We should take off our hats to them and wish them godspeed. In their destruction of aphides and thrips they are among our best friends. The camel-cricket is another active destroyer of injurious insects. Why do not our schools teach a little practical natural history? Once, when walking in the Catskills, I saw the burly driver of a stage-load of ladies bound out of his vehicle to kill a garter-snake, the pallid women looking on, meanwhile, as if the earth were being rid of some terrible and venomous thing. They ought to have known that the poor little reptile was as harmless as one of their own garters, and quite as useful in its way. Every country boy and girl should be taught to recognize all our helpers in our incessant fight with insect enemies—a fight which must be maintained with more organized vigor and intelligence than at present, if horticulture is ever to reach its best development.
Wasps and hornets often swarm about the sweet and early ripe varieties. A wide-mouthed bottle partially filled with molasses and water will entrap and drown great numbers of these ugly customers. Some of our favorite birds try our patience not a little. During the early summer I never wearied of watching the musical orioles flashing with their bright hues in and out of the foliage about the house; but when the early grapes were ripe, they took pay for their music with the sang-froid of a favorite prima donna. On one occasion I saw three or four alight on a Diana vine, and in five minutes they had spoiled a dozen clusters. If they would only take a bunch and eat it up clean, one would readily share with them, for there would be enough for all; but the dainty little epicures puncture an indefinite number of berries, merely taking a sip from each. Then the wasps and bees come along and finish the clusters. The cardinal, cat-bird, and our unrivalled songster the wood-thrush, all help themselves in the same wasteful fashion. One can't shoot wood-thrushes. We should almost as soon think of killing off our Nilssons, Nevadas, and Carys. The only thing to do is to protect the clusters; and this can be accomplished in several ways. The most expeditious and satisfactory method is to cover the vines of early grapes with cheap mosquito netting. Another method is to make little bags of this netting and inclose each cluster. Last fall, two of my children tied up many hundreds of clusters in little paper bags, which can be procured at wholesale for a trifling sum. The two lower corners of the paper bags should be clipped off to permit the rain to pass freely through them. Clusters ripen better, last longer on the vine, and acquire a more exquisite bloom and flavor in this retirement than if exposed to light as well as to birds and wasps. Not the fruit but the foliage of the grape-vine needs the sun.
Few of the early grapes will keep long after being taken from the vine; but some of the later ones can be preserved well into the winter by putting them in small boxes and storing them where the temperature is cool, even, and dry. Some of the wine-grapes, like Norton's Virginia, will keep under these conditions almost like winter apples. One October day I took a stone pot of the largest size and put in first a layer of Isabella grapes, then a double thickness of straw paper, then alternate layers of grapes and paper, until the pot was full. A cloth was next pasted over the stone cover, so as to make the pot water-tight. The pot was then buried on a dry knoll below the reach of frost, and dug up again on New Year's Day. The grapes looked and tasted as if they had just been picked from the vine.
