Why Grow Triple Crown Blackberries?

Triple Crown is named for its three strengths: flavor, productivity, and vigor. It is widely considered one of the highest-yielding thornless blackberries available to home growers, and a mature plant can produce a genuinely startling amount of fruit — often twenty pounds or more in a good season.

The berries are large, glossy, and firm, with a rich sweet flavor that holds up well for fresh eating, freezing, and baking. Because the fruit is firmer than a Sweetie Pie or a boysenberry, it also handles picking and storage better, which makes Triple Crown the practical choice if you want to put up a freezer full of berries rather than eat them all standing over the plant.

What You Receive

Four (4) tissue culture Triple Crown starter plants. Tissue culture means each plant was grown in a sterile laboratory environment from a single healthy parent, so every plant arrives disease-free and genetically true to the variety. There is no seed variation and no risk of importing pests or disease along with a field-dug bare-root cutting.

These arrive as young, actively growing starters, not dormant bare-root canes. They are small on arrival by design — small plants transplant with far less shock and typically catch up to larger nursery stock inside a single season.

Growing Triple Crown: Zones, Sun, and Soil

Hardy in USDA Zones 5 through 9. Plant in full sun, six hours minimum, for the heaviest crop.

Triple Crown wants well-draining soil with a pH between 5.5 and 7.0 and will sulk in anything that stays soggy. Raised beds or large containers solve heavy soil. Space plants four to six feet apart — this is a vigorous variety and it will use the room. The canes are semi-erect and grow long, so a sturdy trellis is not optional if you want manageable plants and clean fruit.

Care and Pruning

Water deeply once or twice weekly during the growing season and mulch to conserve moisture. Feed with a balanced fertilizer as growth begins in early spring.

Triple Crown fruits on second-year canes. Remove spent canes at ground level immediately after harvest and train the current year's new canes onto the trellis for next season. Tip-prune new canes around four to five feet to force lateral branching, which is where most of the fruit sets.

Frequently Asked Questions

When will my plants fruit?
Expect a light crop the second summer and full production in year three.

How does Triple Crown compare to Sweetie Pie?
Sweetie Pie is sweeter and softer, better for eating straight off the plant. Triple Crown yields more and produces a firmer berry that stores and freezes better. Many growers plant both.

Do I need more than one plant?
No, Triple Crown is self-fertile. Additional plants simply increase your harvest.

Can I grow them in containers?
Yes, but use a large one — 15 gallons or more — because this variety is vigorous. Provide a trellis and water more frequently than in-ground plants.

How do you ship live plants?
Packed in a sturdy box that keeps plants upright and protected, shipped fast to minimize transit time. Arrives alive guaranteed.
