redloon's Blackberry 'Natchez' x 6 Ripening
Ordered from Pense Nursery. I ordered 6 plants each of two erect thornless varieties.
Type – Thornless, erect to semi-erect.
Date of Release – 2007.
Fruit Size – Large, average 8 to 9 g/berry; comparable to Apache and larger than Ouachita.
Flavor/Sweetness – Good, rated comparable to Arapaho; soluble solids (percent sugar) averages 9.5%.
Yield – Yields twice that of Arapaho in research trials; comparable to Ouachita and Apache.
Maturity Date – Ripens beginning approximately June 3 at Clarksville, Arkansas. Ripening season earlier than Ouachita.
Disease Resistance – No substantial common diseases observed; no orange rust observed; very limited fruit anthracnose observed; no double blossom/rosette observed.
Comments – Fruit storage and handling potential very good, usually exceeding Arapaho and comparable to other Arkansas thornless cultivars.
Growing guidelines from University of Arkansas:
“Many soil types are suitable for blackberry production. However, the preferred soil pH ranges from 5.5 to 6.5, and good soil drainage is essential.”
“Fertilizing the second year, and thereafter, should be based on soil test recommendations alongside the rows in February. Side-dress with ammonium nitrate after harvest at 5 pounds per 100 feet of row.”
“Blackberry plants send up new canes from crowns or from buds formed on the roots. These canes grow through one season, produce a crop of fruit the second year and then die soon after harvest. Remove old canes immediately after harvest so that the new shoots develop sturdy canes.”
“Top the ends of new canes during the summer at a height of 36 to 48 inches. This limits cane height and forces side laterals which bear the fruiting clusters the following year.”
“During the summer, it is very important to remove suckers growing up outside of the desired row. Summer prune the remaining laterals or side branches to a manageable length. Winter prune the laterals to 14 to 16 inches for convenient harvesting and larger berries. Winter removal of excessively wide summer growth removes the most fruitful canes. In late winter, remove the remaining dead and weak wood. Leave healthy, vigorous canes spaced about six canes per foot in a row about 12 to 18 inches wide.”
“Harvesting: Blackberries are highly perishable. They should be harvested as soon as ripe, handled very carefully and either placed in cold storage or used without delay. It may be necessary to harvest daily to prevent loss of fruit and the spread of molds and other diseases.”
Pruning and training guidelines from West Virginia University:
“For 1-2 years after planting, thornless blackberry primocanes tend to grow along the ground, like a vine. In the second and succeeding years, shoot growth is more vigorous and upright. Tie these new shoots to the trellis when they reach a length of four to six feet. Some growers prefer to wait until after harvest to remove old canes before tying new shoots to the trellis.”
“When the new shoots of erect blackberries reach thirty-six inches in height, cut off the tips. This will force branching lower on the canes and will cause the canes to thicken, making them better able to support a heavy fruit crop. During the winter, prune the laterals to twelve to fourteen inches for convenient harvesting and larger berries. In late winter, remove any remaining dead or weak wood. Leave healthy, vigorous canes spaced at six canes per linear foot.”
