Triple Crown Pollination Guide
Triple Crown is self-fertile — a single tree will produce fruit without a pollination partner.
You don't need a second tree to get fruit from Triple Crown. It can pollinate itself. That said, having a compatible variety nearby can sometimes improve fruit set and yield through cross-pollination.

About Triple Crown
Triple Crown earns its name with three crowning virtues — thornless canes, exceptional flavor, and massive yields. The large, glossy berries have a complex sweet-tart taste that's superior to most thorny varieties.
Growing Challenges
Semi-erect canes need trellising; late ripening means short harvest window before frost in northern areas; susceptible to spotted wing drosophila.
Frequently Asked Questions
How close does a pollinator need to be to Triple Crown?
For reliable pollination, plant the partner variety within 50–100 feet of Triple Crown. Bees are the primary pollinators and typically work within this range. In practice, a tree in your yard or even a neighbor's nearby tree can work. The closer the trees, the more consistent the fruit set.
Can I grow just one Triple Crown tree?
Yes! Triple Crown is self-fertile and will produce fruit as a single tree. You don't need a second tree, though having one nearby can sometimes improve yield.
