Blackberries and raspberries should be set 3 feet apart in the row, 100 feet requiring thirty to thirty-five plants. Old canes should be pruned out after fruiting and the weaker new canes should be removed when dormant, leaving 6 or 8 inches between the standing canes. Lateral branches should be cut back in early spring to about 1 foot in length and the upright canes cut back to uninjured wood, thus removing about two-thirds of the growth.
Grapes need severe pruning to produce satisfactory yields of good quality. This is best done in late winter. It is a good plan to prune so that from 15 to 30 or possibly 40 buds are left on each mature vine, depending upon the vitality of the plant. Two or three clusters of fruit will develop on the shoot that grows from each bud. A 100-foot row of grapes will require twelve plants. There are many fine varieties of grapes and several can be used in a single row.
In ordering stock for planting, care should be exercised in making sure of the reliability of the nursery. As a general rule it is better to order from a nursery in the vicinity, thus eliminating losses due to shipping great distances and also making sure that the varieties or strains were grown for use in the area in question. Upon the arrival of the stock from the nursery, it should be “heeled in” at once. That is, the roots should be covered in a trench so that they will not dry out before they can be planted in the desired location. In the case of a few trees that can be set immediately, this is not necessary.
Nearly all country places have sufficient area for planting small fruits and, as is the case with vegetables, freshness and fine-flavored varieties will compensate for the labor involved in growing them. Strawberries, currants, gooseberries, blackberries, red and black raspberries and grapes are especially desirable for home plantings. Some high-quality varieties are given for the choice of the home owner, subject to confirmation by authorities acquainted with specific conditions and intended primarily for home use.

Controlling Insect and Fungous Pests.—Plant pests of various kinds infest tree fruits and small fruits. In general, the best method of controlling leaf-chewing insects is by applying arsenate of lead on the foliage. Care must be taken to avoid staining the fruit with poisonous spray or thorough washing will be necessary before it is safe to consume. The control of other insect pests and fungous plant diseases has been well worked out by agricultural experiment stations throughout the country, and these methods should be sought before attempting any campaign of suppression. A barrel spray pump, mounted on a hand truck or on a vehicle, equipped with plenty of hose will be found satisfactory for spraying plantings of modest size.
Rejuvenating an Old Orchard.—The purchaser of an old-established farm will usually find he has acquired some apple trees of uncertain age and health. In many instances these trees can be renovated and rejuvenated so that they will again bear fruit. If the trees have several sound limbs and are making some growth each year, they may be considered worth saving. On the other hand, broken tops and limbs accompanied by large rotted cavities will create too great an expense if an attempt is made to restore them to usefulness. The varieties should be determined before serious efforts at renovation are undertaken, so that the strenuous work necessary for restoration may not be wasted on undesirable fruit.
Steps in Renovation.—The first operation in renovation is pruning. Most of this should be done in early spring during the dormant season and supplemented in June or July when the trees are in leaf. Large broken limbs and dead wood should be removed, together with interfering branches, and those reaching too high should be headed back. At about the same time that pruning is started the loose bark should be thoroughly scraped off and burned, thus destroying insects and fungi that attack the fruit. Harboring places for further infestations are also thus removed. If the trees are badly in need of pruning, it is best to do the job over a period of two or three years rather than all at one time, due to the tendency of trees to “sucker” and develop a multiplicity of small non-bearing branches.
Spraying, fertilizing and cultivation, where that is possible, should follow the pruning and scraping jobs. Spray schedules and cultural practices best adapted to the region can be obtained without cost by applying to state or county agricultural agencies. Ordinarily two or three years are required to rejuvenate these trees and begin to secure a crop. Production will then increase in quantity and quality during succeeding years.
Bees as Pollinators.—The production of fruits of all kinds is dependent upon pollination of their blossoms by bees and other winged insects. Bees of many species are useful in pollen distribution, but the most important is the honey bee, which is available in larger numbers just at flowering time, seeking nectar from the flowers. In large commercial orchards colonies of honey bees are set at regular intervals to insure adequate pollination, usually one hive per acre.
