Home Vegetable Gardening Part 17

INSECTS AND DISEASE

For white-grub and cut-worm see pages elsewhere in the text. For rust, which frequently injures the leaves so seriously as to cause practical loss of crop, choose hardy varieties and change bed frequently.

Spraying with Bordeaux, 5-5-50, four or five times during first season plants are set, and second season just before and just after blossoming, will prevent it. In making up your strawberry list remember that some varieties have imperfect, or pistillate blossoms, and that when such varieties are used a row of some perfect-flowering (bi- s.e.xual) sort must be set every nine to twelve feet.

VARIETIES

New strawberries are being introduced constantly; also, they vary greatly in their adaptation to locality. Therefore it is difficult to advise as to what varieties to plant. The following, however, have proved satisfactory over wide areas, and may be depended upon to give satisfaction. Early crop:--Michel's Early, Haverland, Climax; mid- season crop:--Bubach No. 5, Brandywine, Marshall, Nic. Ohmer, Wm. Belt, Glen Mary, Sharplesss; late crop:--The Gandy, Sample, Lester Lovett.

The blackberry, dewberry and raspberry are all treated in much the same way. The soil should be well drained, but if a little clayey, so much the better. They are planned preferably in early spring, and set from three or four to six or seven feet apart, according to the variety.

They should be put in firmly. Set the plants in about as deep as they have been growing, and cut the canes back to six or eight inches. If fruit is wanted the same season as bushes are set, get a few extra plants--they cost but a few cents--and cut back to two feet or so.

Plants fruited the first season are not likely to do well the following year. Two plants may be set in a place and one fruited. If this one is exhausted, then little will be lost. Give clean cultivation frequently enough to maintain a soil mulch, as it is very necessary to retain all the moisture possible. Cultivation, though frequent, should be very shallow as soon as the plants get a good start. In very hot seasons, if the ground is clean, a summer mulch of old hay, leaves or rough manure will be good for the same purpose.

In growing, a good stout stake is used for each plant, to which the canes are tied with some soft material. Or, a stout wire is strung the length of the row and the canes fastened to this--a better way, however, being to string two wires, one on either side of the row.

Another very important matter is that of pruning. The plants if left to themselves will throw up altogether too much wood. This must be cut out to four or five of the new canes and all the canes that have borne fruit should be cut and burned each season as soon as through fruiting.

The canes, for instance, that grow in 1911 will be those to fruit in 1912, after which they should be immediately removed. The new canes, if they are to be self-supporting, as sometimes grown, should be cut back when three or four feet high.

It is best, however, to give support. In the case of those varieties which make fruiting side-shoots, as most of the black raspberries (blackcaps) do, the canes should be cut back at two to three feet, and it is well also to cut back these side shoots one-third to one-half, early in the spring.

In cold sections (New York or north of it) it is safest to give winter protection by "laying down" the canes and giving them a mulch of rough material. Having them near the ground is in itself a great protection, as they will not be exposed to sun and wind and will sometimes be covered with snow.

For mulching, the canes are bent over nearly at the soil and a shovelful of earth thrown on the tips to hold them down; the entire canes may then be covered with soil or rough manure, but do not put it on until freezing weather is at hand. If a mulch is used, it must be taken off before growth starts in the spring.

THE BLACKBERRY

The large-growing sorts are set as much as six by eight feet apart, though with careful staking and pruning they may be comfortably handled in less s.p.a.ce. The smaller sorts need about four by six. When growth starts, thin out to four or five canes and pinch these off at about three feet; or, if they are to be put on wires or trellis, they may be cut when tied up the following spring. Cultivate, mulch and prune as suggested above.

Blackberries will do well on a soil a little dry for raspberries and they do not need it quite so rich, as in this case the canes do not ripen up sufficiently by fall, which is essential for good crops. If growing rank they should be pinched back in late August. When tying up in the spring, the canes should be cut back to four or five feet and the laterals to not more than eighteen inches.

Blackberry enemies do not do extensive injury, as a rule, in well- cared-for beds. The most serious are: (1) the rust or blight, for which there is no cure but carefully pulling and burning the plants as fast as infested; (2) the blackberry-bush borer, for which burn infested canes; and (3) the recently introduced bramble flea-louse, which resembles the green plant-louse or aphis except that it is a brisk jumper, like the flea-beetle. The leaves twist and curl up in summer and do not drop off in the fall. On cold early mornings, or wet weather, while the insects are sluggish, cut all infested shoots, collecting them in a tight box, and burn.

BLACKBERRY VARIETIES

As with the other small fruits, so many varieties are being introduced that it is difficult to give a list of the best for home use. Any selections from the following, however, will prove satisfactory, as they are tried-and-true:--Early King, Early Harvest, Wilson Junior, Kittatinny, Rathburn, Snyder, Erie.

THE DEWBERRY

This is really a trailing blackberry and needs the same culture, except that the canes are naturally slender and trailing and therefore, for garden culture, must have support. They may be staked up, or a barrel hoop, supported by two stakes, makes a good support. In ripening, the dewberry is ten to fourteen days earlier than the blackberry, and for that reason a few plants should be included in the berry patch. Premo is the earliest sort, and Lucretia the standard.

RASPBERRY

The black and the red types are distinct in flavor, and both should be grown. The blackcaps need more room, about three by six or seven feet; for the reds three by five feet will be sufficient. The blackcaps, and a few of the reds, like Cuthbert, throw out fruiting side branches, and should have the main canes cut back at about two and a half feet to encourage the growth of these laterals, which, in the following spring, should be cut back to about one-third their length. The soil for raspberries should be clayey if possible, and moist, but not wet.

RASPBERRY ENEMIES

The orange rust, which attacks the blackberry also, is a serious trouble. Pull up and burn all infested plants at once, as no good remedy has as yet been found. The cut-worm, especially in newly set beds, may sometimes prove destructive of the sprouting young canes. The raspberry-borer is the larva of a small, flattish, red-necked beetle, which bores to the center of the canes during summer growth, and kills them. Cut and burn.

RASPBERRY VARIETIES

Of the blackcaps, Gregg, McCormick, Munger, c.u.mberland, Columbian, Palmer (very early), and Eureka (late), are all good sorts. Reds: Cuthbert, Cardinal (new), Turner, Reliance, The King (extra early), Loudon (late). Yellow: Golden Queen.

CURRANTS

The currant and gooseberry are very similar in their cultural requirements. A deep, rich and moist soil is the best--approaching a clayey loam. There need be no fear of giving too much manure, but it should be well rotted. Plenty of room, plenty of air, plenty of moisture, secured where necessary by a soil or other mulch in hot dry weather, are essential to the production of the best fruit.

The currant will stand probably as much abuse as any plant the home gardener will have to deal with. Stuck in a corner, smothered in sod, crowded with old wood, stripped by the currant-worm, it still struggles along from year to year, ever hopefully trying to produce a meager crop of poor fruit. But these are not the sort you want. Although it is so tough, no fruit will respond to good care more quickly.

To have it do well, give it room, four or five feet each way between bushes. Manure it liberally; give it clean cultivation, and as the season gets hot and dry, mulch the soil, if you would be certain of a full-sized, full-flavored crop. Two bushes, well cared for, will yield more than a dozen half-neglected ones. Anywhere north of New York a full crop every year may be made almost certain.

PRUNING CURRANTS

Besides careful cultivation, to insure the best of fruit it is necessary to give some thought to the matter of pruning. The most convenient and the most satisfactory way is to keep it in the bush form. Set the plants singly, three or four feet apart, and so cut the new growth, which is generously produced, as to retain a uniform bush shape, preferably rather open in the center.

The fruit is produced on wood two or more years old. Therefore cut out branches either when very small, or not until four or five years later, after it has borne two or three crops of fruit. Therefore, in pruning currants, take out (1) superfluous young growth; (2) old hard wood (as new wood will produce better fruit); and (3) all weak, broken, dead or diseased shoots; (4) during summer, if the tips of the young growths kept for fruiting are pinched off, they will ripen up much better-- meaning better fruit when they bear; (5) to maintain a good form, the whole plant may be cut back (never more than one-third) in the fall.

In special situations it may be advisable to train the currant to one or a few main stems, as against a wall; this can be done, but it is less convenient. Also it brings greater danger from the currant-borer.

The black currant, used almost entirely for culinary or preserving purposes, is entirely different from the red and white ones. They are much larger and should be put five to six feet apart. Some of the fruit is borne on one-year-old wood, so the shoots should not be cut back.

Moreover, old wood bears as good fruit as the new growth, and need not be cut out, unless the plant is getting crowded, for several years. As the wood is much heavier and stronger than the other currants, it is advisable gradually to develop the black currants into the tree form.

ENEMIES OF THE CURRANT

The worst of these is the common currant-worm. When he appears, which will be indicated by holes eaten in the lower leaves early in spring, generally before the plants bloom, spray at once with Paris green. If a second brood appears, spray with white h.e.l.lebore (if this is not all washed off by the rain, wipe from the fruit when gathered). For the borer, cut and burn every infested shoot. Examine the bushes in late fall, and those in which the borers are at work will usually have a wilted appearance and be of a brownish color.

VARIETIES OF CURRANTS

Red Dutch, while older and smaller than some of the newer varieties, is hardier and not so likely to be hurt by the borer. London Market, Fay's Prolific, Perfection (new), and Prince Albert, are good sorts. White Grape is a good white. Naples, and Lee's Prolific are good black sorts.

THE GOOSEBERRY

This is given practically the same treatment as the currant. It is even more important that it should be given the coolest, airiest, location possible, and the most moist soil. Even a partially shaded situation will do, but in such situations extra care must be taken to guard against the mildew--which is mentioned below. Summer mulching is, of course, of special benefit.

In pruning the gooseberry, it is best to cut out to a very few, or even to a single stem. Keep the head open, to allow free circulation of air.

The extent of pruning will make a great difference in the size of the fruit; if fruit of the largest size is wanted, prune very close. All branches drooping to the ground should be removed. Keep the branches, as much as possible, from touching each other.
