Prime Ark® 45 is a new blackberry release from the University of Arkansas' breeding program. It is a thorny primocane-bearing blackberry with an erect growing habit. Fruit size is medium-large and trials indicate that Prime Ark® 45 is more productive than Prime Jim. Fruit holds up well after picking and is suitable for shipping. The floricane fruiting season is after Prime Jim and Natchez and before Ouachita. Early indications are that the primocane crop ripens 12-14 days later than Prime Jim. Ripening may be too late for some northern areas, but will extend the blackberry season for situations where late fruit is desired. High temperatures during flowering will reduce yields.

special features
Fall-bearing or primocane blackberries respond favorably to tipping! As the primocanes reach 12-15” in height, break or cut ¾-1” off the tip of each cane to force branching. Tip again when branches reach 30”. This process stimulates earlier fruit development, keeps plant height in check, and increases yield.
