Fruit are long, cylindrical, slightly flattened in shape, and very attractive with a glossy, black finish. Fruit size and yield are larger than Shawnee. Thorny CultivarsĬhickasaw –Vigorous, erect canes. Thorny cultivars also grow but may not be as long-lived due to rosette disease. Many people choose the thornless cultivars because of the lack of thorns. See your local county MSU Extension office for more information on specific pest control options. Other pest and abiotic issues include cane borers, spotted wing drosophila fruit fly and white drupelet disorder. Thornless cultivars have some tolerance to the disease. Eradication of wild blackberries aids in control. No thorny cultivar is immune to this disease, and it must be controlled by a spray and cultural program. Rosette or double blossom, a fungal disease, is a significant factor limiting blackberry production in Mississippi. A grower must weigh the benefits of more frequent mowing (fewer disease problems, fewer dead canes in a row) versus less frequent mowing (possibly higher yields). A 2- to 3-year mowing rotation may prove satisfactory. A longer growing season in southern Mississippi allows time for growth of new canes in summer and fall (to provide for the next crop).Īnnual mowing may weaken the plants. Growers sometimes mow plants to ground level immediately after harvest and then dispose of all mowed plant material. The new canes will have fruit the following year. New canes from the roots will replace these canes. Fruiting canes (also called floricanes) must be removed after harvest. ![]() Vegetative canes (also called primocanes) develop the first year, bear fruit the second year, and die after fruiting. Prune hedgerows to a width of 3–4 feet.īlackberry canes are biennial. Vigorous plants may require topping two to four times. New canes produced in the second and later years will be erect and need to be topped at 3–4 feet in June to encourage lateral branching. Keep them within the row area since they will produce fruit the next year. In the first growing season, canes from erect blackberries will be semi-erect or almost trailing. In following years, use 11 pounds of fertilizer per 100 feet in March and 5.5 pounds of fertilizer per 100 feet of row immediately after harvest, evenly applied over a 3-foot band. Spread the fertilizer evenly over a 2-foot band. Increase the fertilizer rate the next year to 11.5 pounds per 100 feet of row applied in February and 5.5 pounds per 100 feet in June. Place the root cuttings 1–2 inches deep in well-prepared soil.įertilize the plants 1 month after planting with 10-10-10 or 13-13-13 and again in late June (using 5.5 pounds per 100 feet of row in a 2-foot band). Space the root cuttings or plants 2 feet apart within rows that are 10–12 feet apart to form a hedgerow. They should be 4–7 inches long and one-eighth to one-half-inch thick (about the size of a pencil). Note that it is illegal to propagate some cultivars that have plant patent protection. Root cuttings are collected from healthy plants during the dormant season. For commercial plantings, bare-root plants are the most common. ![]() Container-grown blackberry plants are more expensive, but these will also grow well. Raised beds are recommended for locations with poorly drained soils or in areas prone to flooding.Įstablish blackberries in late February or early March by planting plants or root cuttings. ![]() In general, their root systems do not tolerate wet soils. Blackberries can be grown on sandy soils if a good irrigation system is used. The most suitable soils are high in organic matter and have a pH of 6.0–6.5. Establishment and Cultural Practicesīlackberries can tolerate many soil types but grow best in full sun and well-drained soil. Although trailing types will grow here, the erect or upright blackberry is the most popular type grown in Mississippi because they require little or no trellising. Home plantings of improved cultivars of blackberries offer high-quality fruit and ease of harvesting without the inconvenience of pests found in wild blackberries.
