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

About Ouachita
Ouachita is the thornless blackberry that laughs at summer heat — bred in Arkansas for hot, humid conditions where other varieties struggle. Firm, sweet berries with excellent shelf life make it a commercial favorite.
Growing Challenges
Erect canes still benefit from trellising for heavy crops; needs consistent irrigation in extreme heat; moderate winter hardiness.
Frequently Asked Questions
How close does a pollinator need to be to Ouachita?
For reliable pollination, plant the partner variety within 50–100 feet of Ouachita. 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 Ouachita tree?
Yes! Ouachita 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.
