Best Way To Grow Blackberries And Loganberries

Soil and Situation. Blackberries And Loganberries succeed in most ordinary garden soils except those of a very dry, poor nature. They will grow in sunny or partially shaded positions. Soil should be prepared exactly as for raspberries.

Planting. Canes should be spaced 8 ft. apart, and if there is more than one row 8 ft. should be allowed between rows. Very vigorous varieties such as Himalaya Berry should be spaced 12 ft. apart each way. Planting may be done at any time from mid-October to March as for raspberries.

Training. Common practice is to grow loganberries, blackberries, and allied fruits against walls or fences. Alternatively they may be grown in the open tied to wires strained between posts as for raspberries. The uppermost wire should be 7 ft. above ground level.

Pollination. Most varieties are self-fertile, i.e. they will produce fruit when pollinated with their own pollen. A few varieties of hybrid berry are self-sterile or produce no pollen and, in consequence, should be planted with other kinds.

Pruning. After planting, cut all canes back to within 12 in. of ground level. Young canes should not be allowed to bear fruit the first year. In subsequent years, prune as soon as possible after the crop has been gathered. Cut out to ground level all old fruiting canes and train young canes in their place. With very vigorous varieties such as Himalayan Giant, two or three old canes per plant may be kept for a second season. Do not retain more than ten new canes per plant. Select the sturdiest and cut out the remainder early in the summer. It does not matter if those retained are suckers, i.e. growing direct from the root.

Routine Cultivation. As for raspberries.

Routine Pest Control. Usually unnecessary, as foes are dealt with as noted. If cane spot is troublesome, cut out and burn all affected canes and spray about the middle of March with limetsulphur wash at twice the normal winter strength.

Propagation of Blackberries And Loganberries. May be effected by division of old plants in autumn or winter, but the best method is to tip-root young canes. This is done by bending such canes down in July or August and pegging the tips to the soil. If kept moist, roots will be formed rapidly and by the autumn the canes can be severed from the parents. A few weeks later they may be lifted and transplanted to a nursery bed.

Varieties of Blackberry. Bedford Giant, early; Himalaya Giant, mid-season ; John Innes, late; Merton Thornless, mid-season; Oregon Thornless, mid-season; Parsleytleaved, mid-season.
