Growing & Maintenance Tips
Blackberries grow best in a slightly acidic, rich soil and full sun. If planting in heavy clay, add peat moss or compost. Blackberry canes should be thinned yearly, removing any canes more than two years old. Hardiness, maintenance of moisture, and weed control can be improved with an application of mulch or compost in late fall. Fruit is produced on second-year canes.
Notes
Triple Crown Blackberries are self-pollinating, but will increase production if another variety is nearby.  They are more upright than other cultivars. Avoid growing Blackberries where potatoes, grapes, tomatoes, raspberries, peppers, apples or peaches had once previously grown. These plants share similar diseases and pests with Blackberries. The botanical name for Thornless Blackberry has been updated from Blackberry x 'Triple Crown' to Rubus laciniatus 'Triple Crown'.
