Prime Ark Traveler Thornless Blackberry
Now grow thornless blackberries like you do primo cane raspberries. Prime Ark Traveler produces prolific delicious harvests of sweet blackberries on first year canes that don't require a trellis. Here's how you do it. Plant the thornless cane and let it establish for a year. It will grow to six feet tall or more and produce a crop in August. Cut it to the ground each late fall. In late spring when it reaches 3 to 4 feet in height, cut 6 inches off the tip of each cane. The cane will produce branches and then flowers which in August and September in the Northwest will give you loads of delicious medium to large firm sweet berries. After the side branches reach about 15 inches you can pinch them back for even more production. USDA Zones 6-9. Traveler requires only 300 chilling hours. It is new from the U. of Arkansas. 4" Pot.
