Summary

Thornless, upright canes and sweet summer harvests make ‘Ouachita’ a reliable backyard blackberry.

Rubus ‘Ouachita’ is an erect, thornless blackberry variety valued for its firm, flavorful fruit and manageable growth habit. In spring, clusters of white flowers attract pollinators, followed by glossy, deep purple-black berries in summer.

This variety grows in a naturally upright, shrub-like form and does not require trellising, though light support can help maintain neat growth and simplify harvesting.

‘Ouachita’ is self-pollinating, so one plant will produce fruit. For heavier yields, plant multiple shrubs 3–4 feet apart. Plants typically begin fruit production in their second growing season.

Heat tolerant and noted for resistance to Rosette Disease, this cultivar performs reliably across its hardiness range.

Care

Blackberry Plant Care

Plant in full sun for best flowering and fruit production.

Grow in moist, well-drained, loamy soil. Water regularly during establishment and during extended dry periods. Keep soil evenly moist but not saturated.

Apply slow release fertilizer in spring to encourage strong cane growth and fruiting.

Mulch around the base to conserve moisture and moderate soil temperature.

Remove old, spent canes after fruiting to encourage healthy new growth. While trellising is not required, light support can improve air circulation and ease harvesting.
