Plant Care & Growing Tips

Proper care is essential to ensure your Osage thornless blackberry plants thrive and produce an abundance of delicious fruit. These plants are relatively easy to maintain, making them suitable for gardeners of varying experience levels. Begin by selecting a site that receives full sun, meaning at least 6-8 hours of direct sunlight per day. Adequate sunlight is crucial for fruit production and flavor development. While these plants are adaptable, they prefer well-draining, slightly acidic soil with a pH between 5.5 and 7.0. Amending heavy clay soils with organic matter like compost can significantly improve drainage and provide essential nutrients for your thornless blackberry bush.

When planting your blackberry starter plugs, ensure they are spaced approximately 3-5 feet apart in rows that are 6-8 feet apart. This spacing allows for proper air circulation and easy access for harvesting and pruning. Water newly planted plugs regularly to help them establish, keeping the soil consistently moist but not waterlogged. Once established, Osage blackberries require about 1-2 inches of water per week, either from rainfall or irrigation, especially during dry spells and fruit development. Fertilize in early spring with a balanced granular fertilizer or a slow-release organic option, following the product instructions. Avoid over-fertilizing, which can promote excessive foliage growth at the expense of fruit production.

Pruning is a vital aspect of caring for floricane-fruiting blackberries like ‘Osage’. Since they produce fruit on second-year canes (floricanes), you should remove all canes that have fruited at the base after harvest. New canes (primocanes) will emerge and grow during the first year, then produce fruit the following year. Thin out weaker primocanes in late winter or early spring, leaving 4-6 strong canes per linear foot of row. Training canes to a trellis or support system is highly recommended for these semi-erect plants to keep them upright, improve air circulation, and facilitate harvesting. Winter protection may be necessary in colder climates (USDA zones 5-6) to prevent cane damage from severe freezes. Learning how to grow Osage blackberry successfully involves consistent watering, proper nutrition, and timely pruning.
