Blackberries (Thornless & Semi-erect)
Some type of trellis support is recommended and a 3-4 wire trellis works best for this type of plant. Tip 1st year canes when they reach 5 feet high in midsummer. Canes that fruited can be removed anytime after they have been harvested. Thin the remaining canes to 8 canes per running yard of row. If grown in a hedgerow, thin canes to 6-8 canes per hill. Wrap the laterals around the wires before Mid-September, before canes become woody and brittle.
Sometimes thornless blackberries are managed by tying them to a stake. In the staked-hill system, the canes are wrapped around a stake 2 inches in diameter, tied in 2 to 3 places, and cut off to the height of the stake at 5-6 feet above ground level. The plants are set 5-8 feet apart in every direction and restricted to a clump. This is an easy to maintain system and can be an attractive addition to the home garden landscape. A trellis or staking is highly recommended for the semi-erect, trailing blackberries in order to keep the fruit clean and minimize canes breaking.
