Easy to pick berries with great flavor that has garnered rave reviews!

Triple Crown Thornless Blackberry plants are productive and vigorous growers, producing large, glossy black, firm fruits! With a tasty blend of sweet and tart, these berries are great for pies and baking. Seeds are smaller than those of wild blackberries.

The thornless, semi-erect canes set fruit uniformly, making for easy picking. Triple Crown is well suited for berry farms, pick-your-own operations, and backyard home gardens. This fast-growing berry plant yields 13 lbs. of fruit per plant!

How to Grow Triple Crown Thornless Blackberry Plants

This variety is a summer-bearing floricane, providing you with one large harvest late season, in early August. This is a heat-tolerant blackberry plant that can grow in partial shade but prefers full sun. Plant in well-draining soil, and water well the first season.

The semi-erect canes of the Triple Crown grow best when supported by a trellis - especially when under heavy fruit load. Prune or top new canes at 5-6 feet. Tip laterals to keep at 3-4 feet. After harvest, remove old fruiting canes.

Triple Crown Thornless Blackberry plants are self-pollinating and can be propagated by encouraging the tips of canes to root into the soil. This plant only requires about 300 chill hours.
