How to Grow White Raspberries

Select a planting site in 50 percent shade. The seedlings grow best in shade, but mature white raspberries grow best in full sun.

Plant white raspberry seeds in rich soil. An ideal soil mixture for white raspberries consists of 40 percent red clay, 40 percent organic compost and 20 percent sand.

Water the white raspberry seeds with 1 to 2 inches of water per week during the first growing season. The seedlings should sprout in 40 to 120 days and be fully mature after the first growing season.

Apply 10 lbs. of organic compost and 1 oz. of 4-14-8 fertilizer for every 100 square feet of white raspberry plants in the spring. Repeat this application in the early summer. Water each mature plant with 1 1/2 gallons of water per week.

Prune white raspberries with pruning shears during the winter when the plant is dormant. Remove any dead or diseased growth. Remove any additional growth older than two years to maintain a high rate of fruit production.

Place posts in the ground along the rows of white raspberry plants at 13-foot intervals. Suspend heavy wire between the posts at a height of 16 inches, 32 inches and 48 inches. Tie the white raspberry vines to each wire with flexible twine as they reach the required height.
