For raspberries, virus-indexed, tissue-cultured plants should be planted in the early spring. Raspberries should not be planted in poorly drained soils or after any of the verticillium-susceptible crops (tomatoes, potatoes, peppers, eggplant, strawberries). If available, use tissue-cultured blackberries as well; however, dormant canes may also be planted. In-row spacings (spaces between the plants) are as follows: red raspberries, 24 inches; black raspberries, 30 inches; purple raspberries, 36 inches; blackberries, 36 to 60 inches. Between-row spacing should be no less than 8 feet, although the spacing depends on the size of the equipment that will be used to maintain the planting. Between rows, allow at least 4 feet more than the width of the widest implement to be used in the planting. Remove flower blossoms in the first year to encourage plant establishment.
