CHAPTER XXV
CURRANTS—CHOICE OF SOIL, CULTIVATION, PRUNING, ETC.

They wore "curns" in our early boyhood, and "curns" they are still in the rural vernacular of many regions. In old English they were "corrans," because the people associated them with the raisins of the small Zante grape, once imported so exclusively from Corinth as to acquire the name of that city.

Under the tribe Grossulariae of the Saxifrage family we find the Ribes containing many species of currants and gooseberries; but, in accordance with the scope of this book, we shall quote from Professor Gray (whose arrangement we follow) only those that furnish the currants of cultivation.

" Ribes rubrum , red currant, cultivated from Europe, also wild on our northern border, with straggling or reclining stems, somewhat heart-shaped, moderately three to five lobed leaves, the lobes roundish and drooping racemes from lateral buds distinct from the leaf buds; edible berries red, or a white variety."

This is the parent of our cultivated red and white varieties. Currants are comparatively new-comers in the garden. When the Greek and Roman writers were carefully noting and naming the fruits of their time, the Ribes tribe was as wild as any of the hordes of the far North, in whose dim, cold, damp woods and bogs it then flourished, but, like other Northern tribes, it is making great improvement under the genial influences of civilization and culture.

Until within a century or two, gardeners who cultivated currants at all were content with wild specimens from the woods. The exceedingly small, acid fruit of these wildings was not calculated to inspire enthusiasm; but a people possessing the surer qualities of patience and perseverance determined to develop them, and, as a result, we have the old Bed and White Dutch varieties, as yet unsurpassed for the table. In the Victoria, Cherry, and White Grape, we have decided advances in size, but not in flavor.

CHOICE AND PREPARATION OF SOIL

The secret of success in the culture of currants is suggested by the fact that nature has planted nearly every species of the Ribes in cold, damp, northern exposures. Throughout the woods and bogs of the Northern Hemisphere is found the scraggy, untamed, hurdy stock from which has been developed the superb White Grape. As with people, so with plants: development does not eradicate constitutional traits and tendencies. Beneath all is the craving for the primeval conditions of life, and the best success with the currant and gooseberry will assuredly be obtained by those who can give them a reasonable approach to the soil, climate, and culture suggested by their damp, cold, native haunts. As with the strawberry, then, the first requisite is, not wetness, but abundant and continuous moisture. Soils naturally deficient in this, and which cannot be made drought-resisting by deep plowing and cultivation, are not adapted to the currant. Because this fruit is found wild in bogs, it does not follow that it can be grown successfully in undrained swamps. It will do better in such places than on dry, gravelly knolls, or on thin, light soils; but our fine civilized varieties need civilized conditions. The well-drained swamp may become the very best of currant fields; and damp, heavy land, that is capable of deep, thorough cultivation, should be selected if possible. When such is not to be had, then, by deep plowing, subsoiling, by abundant mulch around the plants throughout the summer, and by occasional waterings in the garden, counteracting the effects of lightness and dryness of soil, skill can go far in making good nature's deficiencies.

Next to depth of soil and moisture, the currant requires fertility. It is justly called one of the "gross feeders," and is not particular as to the quality of its food, so that it is abundant. I would still suggest, however, that it be fed according to its nature with heavy composts, in which muck, leaf-mould, and the cleanings of the cow- stable are largely present. Wood-ashes and bone-meal are also most excellent. If stable or other light manures must be used, I would suggest that they be scattered liberally on the surface in the fall or early spring and gradually worked in by cultivation. Thus used, their light heating qualities will do no harm, and they will keep the surface mellow and, therefore, moist.

The shadowy, Northern haunts of the wild currant also suggest that it will falter and fail under the Southern sun; and this is true, As we pass down through the Middle States, we find it difficult to make thrive even the hardy White and Bed Dutch varieties, and a point is at last reached when the bushes lose their leaves in the hot season, and die. From the latitude of New York south, therefore, increasing effort should be made to supply the currants' constitutional need, by giving partial shade among pear or widely set apple-trees, or, better still, by planting on the northern side of fences, buildings, etc. By giving a cool, half-shady exposure in moist land, the culture of the currant can be extended far to the south, especially in the high mountain regions. Even well to the north it is unprofitable when grown on light, thin, poor land, unless given liberal, skilful culture.

PLANTING, CULTIVATION AND PRUNING

I regard autumn as the best season for planting currants, but have succeeded nearly as well in early spring. If kept moist, there is little danger of the plants dying at any time, but those set in the fall or early spring make, the first year, a much larger growth than those planted when the buds have developed into leaves. Since they start so early, they should be set in the spring as soon as the ground is dry enough to work, and in the autumn, any time after the leaves fall or the wood is ripe. The plants of commerce are one, two and three years old, though not very many of the last are sold. I would as soon have one-year plants, if well rooted, as any, since they are cheaper and more certain to make strong, vigorous bushes, if given generous treatment in the open field, than if left crowded too long in nursery rows. For the garden, where fruit is desired as soon as possible, two and three year old plants are preferable. After planting, cut the young bushes back one-half or two-thirds, so as to ensure new and vigorous growth.

In field culture, I recommend that the rows be five feet apart, and the plants four feet from each other in the row. In this case 2,178 plants are required for an acre. If it is designed to cultivate them both ways, let the plants be set at right angles five feet apart, an acre now requiring 1,742 plants. Sink them two or three inches deeper than they stood in the nursery rows, and although in preparation the ground was well enriched, a shovel of compost around the young plant gives it a fine send-off, and hastens the development of a profitable bush. In the field and for market, I would urge that currants be grown invariably in bush, rather than in tree form. English writers, and some here who follow them, recommend the latter method; but it is not adapted to our climate, and to such limited attention as we can afford to give. The borers, moreover, having but a single stem to work upon, would soon cause many vacancies in the rows.

Currants are grown for market with large and increasing profits; indeed, there is scarcely a fruit that now pays better.

Mr. John S. Collins, of Moorestown, N. J., by the following ingenious, yet simple, invention, is able to drive through his currant and raspberry fields without injuring the plants.

"An ordinary cart is changed by putting in an axle fifteen inches longer than usual, the wheels thus making a track six feet and eight inches wide. The shafts and body of the cart are put just as close to one wheel as possible, so that the horse and the wheel will pass as near together, and as near in a line, as practicable. The axle of the other wheel being long, and bowing up several inches higher than ordinary in the middle, it passes over a row of bushes with little or no damage. Thus, fertilizers can be carried to all parts of the field."

Of course, it would not do to drive through bushes laden with fruit; but after they were picked, such a vehicle could cause but little injury.

In the garden and for home use there is the widest latitude. We may content ourselves, as many do, with a few old Red Dutch bushes that for a generation have struggled with grass and burdocks. We may do a little better, and set out plants in ordinary garden soil, but forget for years to give a particle of food to the starving bushes, remarking annually, with increasing emphasis, that they must be "running out." Few plants of the garden need high feeding more, and no others are more generally starved. I will guarantee that there are successful farmers who no more think of manuring a currant bush than of feeding crows. This fruit will live, no matter how we abuse it, but there are scarcely any that respond more quickly to generous treatment; and in the garden where it is not necessary to keep such a single eye to the margin of profit, many beautiful and interesting things can be done with the currant. The majority will be satisfied with large, vigorous bushes, well enriched, mulched and skilfully pruned. If we choose, however, we may train them into pretty little trees, umbrella, globe, or pyramid in shape, according to our fancy, and by watchfulness and the use of ashes, keep away the borers. In one instance I found a few vigorous shoots that had made a growth of nearly three feet in a single season. With the exception of the terminal bud and three or four just below it, I disbudded these shoots carefully, imbedded the lower ends six inches in moist soil as one would an ordinary cutting, and they speedily took root and developed into little trees. Much taller and more ornamental currant and gooseberry trees can be obtained by grafting any variety we wish on the Missouri species ( Ribes aureum ). These can be made pretty and useful ornaments of the lawn, as well as of the garden. Instead, therefore, of weed- choked, sprawling, unsightly objects, currant bushes can be made things of beauty, as well as of sterling worth.

The cultivation of the currant is very simple. As early in the spring as the ground is dry enough, it should be thoroughly stirred by plow or cultivator, and all perennial weeds and grasses just around the bushes taken out with pronged hoes or forks. If a liberal top-dressing of compost or some other fertilizer was not given in the autumn, which is the best time to apply it, let it be spread over the roots (not up against the stems) before the first spring cultivation. While the bushes are still young, they can be cultivated and kept clean, like any hoed crop; but after they come into bearing—say the third summer —a different course must be adopted. If the ground is kept mellow and bare under the bushes, the fruit will be so splashed with earth as to be unsalable, and washed fruit is scarcely fit for the table. We very properly wish it with just the bloom and coloring which Nature is a month or more in elaborating. Muddy or rinsed fruit suggests the sty, not a dining-room. A mulch of leaves, straw, evergreen boughs— anything that will keep the ground clean—applied immediately after the early spring culture, is the best and most obvious way of preserving the fruit; and this method also secures all the good results which have been shown to follow mulching. Where it is not convenient to mulch, I would suggest that the ground be left undisturbed after the first thorough culture, until the fruit is gathered. The weeds that grow in the interval may be mowed, and allowed to fall under the bushes. By the end of June, the soil will have become so fixed that, with a partial sod of weeds, the fruit may hang over, or even rest upon it, without being splashed by the heavy rains then prevalent. This course is not so neat as clean cultivation or mulching. Few fruit growers, however, can afford to make appearances the first consideration. I have heard of oats being sown among the bushes to keep the fruit clean, but their growth must check the best development of the fruit quite as much as the natural crop of weeds. It would be better to give clean culture, and grow rye, or any early maturing green crop, somewhere else, and when the fruit begins to turn, spread this material under the bushes. On many places, the mowings of weedy, swampy places would be found sufficient for the purpose. After the fruit is gathered, start the cultivator and hoe at once, so as to secure vigorous foliage and healthful growth throughout the entire summer.

Pruning may be done any time after the leaves fall, and success depends upon its judicious and rigorous performance. The English gardeners have recognized this fact, and they have as minute and careful a system as we apply to the grape. These formal and rather arbitrary methods can scarcely be followed practically in our hurried American life. It seems to me that I can do no better than to lay down some sound and general principles and leave their working out to the judgment of the grower. In most instances, I imagine, our best gardeners rarely trim two bushes exactly alike, but deal with each according to its vigor and natural tendencies; for a currant bush has not a little individuality.

A young bush needs cutting back like a young grapevine, and for the same reason. A grapevine left to itself would soon become a mass of tangled wood yielding but little fruit, and that of inferior quality. In like manner nature, uncurbed, gives us a great, straggling bush that is choked and rendered barren by its own luxuriance. Air and light are essential, and the knife must make spaces for them. Cutting back and shortening branches develops fruit buds. Otherwise, we have long, unproductive reaches of wood. This is especially true of the Cherry and other varieties resembling it. The judicious use of the knife, kept up from year to year, will almost double their productiveness. Again, too much very young and too much old wood are causes of unfruitfulness. The skilful culturist seeks to produce and preserve many points of branching and short spurs, for it is here that the little fruit buds cluster thickly. When a branch is becoming black and feeble from age, cut it back to the root, that space may be given for younger growth. From six to twelve bearing stems, from three to five feet high, with their shortened branches and fruit spurs, may be allowed to grow from the roots, according to the vigor of the plant and the space allotted to it. Usually, too many suckers start in the spring. Unless the crop of young wood is valuable for propagation, all except such as are needed to renew the bush should be cut out as early as possible, before they have injured the forming crop. In England, great attention is paid to summer pruning, and here much might be accomplished by it if we had, or would take, the time. ONh8r0LEvdeijeSVszDjVMdg8cGSkc3JY2fxvVh7M86NZi84Zn/jAj6u9ucybpnT
