The fruits of the Dorman are very firm, shiny, light red in color and have large round berries. Berries are slightly tart in flavor. The Dorman produces plants that are vigorous and thrive in hot weather. The plants require trellising. Dorman does well in the southern states.
Plant red and black raspberries 3 feet apart in rows and 6 to 10 feet between the rows. Work soil as deep as possible. Then level soil again. Cut off the tops of red raspberries to about 4 inches. Cut black raspberries to about 2 inches. Plow a furrow about 3 inches deep and spread roots naturally in the row. Pack soil firmly around the roots. Level soil again around the plants. Plants need about an inch of water every 7 to 10 days during hot weather. Cultivate every week or 10 days to keep grass and weeds from plants.
