Raspberry and blackberry canes produce edible fruit that are similar in texture. The main difference is that raspberries have a hollow center while blackberries do not. The canes can be planted in the same area, but it is not recommended to mix the two varieties in the same row because blackberries are more aggressive and require additional pruning. Plant the canes in the spring while they are still dormant and after the danger of frost is past.
Test the soil pH in the planting area with a home soil test kit. Raspberries and blackberries prefer a soil that is slightly acidic. Add ground rock sulfur and mix through the planting bed if the pH is higher than 6.0. Allow the soil to set for several weeks after the application before planting.
Create mound row beds that are 10 inches high and 2 to 3 feet apart by tilling the soil and adding compost to increase the drainage and nutrient value.
Plant the blackberry canes in their own rows with each cane spaced 3 to 4 feet apart. Plant the raspberry canes in their own rows with each cane spaced 2 feet apart. The canes can be planted in the same area, just not intermixed in the same rows.
Plant the canes at the same depth or deeper than they were growing in the nursery. Pack the soil around the canes to hold in place. Keep the roots moist to prevent the canes from drying out.
Cut the canes after planting to 4 to 6 inches in height.
Water the canes well at ground level after planting to prevent the root structure from drying out. Continue to water the canes for several weeks to stimulate root production. Monitor the soil moisture and water during periods of hot dry weather when the first several inches of soil become dry.
