Blackberry 'Triple Crown' (Thornless)
Item BL160

Grow Your Own Fresh Fruit!

'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 everyday for over 30 days. The plant is semi-erect and thornless and bears large, flavorful fruit. 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. 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. Best grown in moist, organically rich, slightly acidic, well-drained soil in full sun to part shade. Intolerant of wet soils. 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.

Notes: 'Triple Crown' is a semi-erect, thornless blackberry cultivar. Good freezing quality. Suited for any grower. This is a self-fruitful, free-standing, thornless shrub that produces one crop of fruit per year. Clusters of white, 5-petaled, rose-like flowers in spring give way to firm, glossy blackberries of excellent eating quality that mature in summer. Although the flowers are attractive, this blackberry is grown primarily as a food crop and it not considered appropriate for ornamental use. Blackberries fruit on two-year old canes. After they have finished fruiting, the canes should be pruned away at the base. The fruit attracts birds. The brown thrasher, gray catbird, northern cardinal, northern mockingbird, and white-eyed vireo commonly nest in blackberry and raspberry thickets. Flowers attract butterflies, notably the western tiger swallowtail. Although the flowers are attractive, this blackberry is grown primarily as a fruit crop and is not considered appropriate for ornamental use.

Pests: Anthracnose, botrytis and verticillium wilt can be serious disease problems. Cane borers and crown borers are potential insect pests.

Planting instructions: May be planted in any well-drained soil. Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the roots meet the stem) is about 1-2" below the soil surface. Cover with soil to the original soil surface and water thoroughly. Roots are shallow – don’t cultivate more than an inch deep. Fertilize at planting and again in late spring.

Choose a sunny site in your garden with good air circulation and water drainage and a pH of 6.0-7.0. Keep roots moist until planting. Work plenty of organic matter into the soil and mulch to keep out weeds. Plant as soon as the soil has warmed. Trim canes to encourage new growth. Plants should be set out at least 2 feet apart in rows 7 feet apart. Trellising is beneficial for cane support. These summer-bearing berries produce fruit on second year canes (floricanes). In the fall of the 2nd year, prune spent canes at ground level and thin others to approximately 4 canes per foot of row. Cut off suckers which grow outside of rows. Trim remaining blackberry canes to 7 feet.
