‘Triple Crown’ is a new Blackberry that will bear consistent huge fruit yields year after year. Fruits ripen to a juicy sweet flavor; over a 5-week period you can harvest and enjoy eating the large black beauties every day for over 30 days. The plant is semi-erect and thornless and bears large, flavorful fruit. These strong canes can support many pounds of fruit without trellising. ‘Triple Crown’ would be a good choice to help extend the blackberry season for home gardeners. They grow successfully in Zones 5-9.
‘Triple Crown’ is a joint release from the USDA-Beltsville and the Pacific West Agricultural Research Service. Early trials indicate that it may ripen earlier than ‘Chester’ and is similar to ‘Chester’ in winter hardiness. ‘Triple Crown’ is best grown in moist, organically rich, slightly acidic, well-drained soil in full sun to part shade. It is intolerant of wet soils and raised beds should be considered in areas with heavy clay soils. Plants are perennial but canes are biennial. For established shrubs, tip-prune new vegetative (non-fruiting) canes in summer. Immediately after fruit harvest, remove all canes that fruited to the ground. In late winter to early spring, remove any canes damaged by winter and thin the remaining canes to 4 or 5 strong, well-spaced canes plus trim the laterals thereof. Plants generally perform best when staked.
