Plant Care & Growing Tips

Proper care is essential for a thriving Columbia Star Blackberry live plant and a bountiful harvest. These plants are relatively easy to grow, but understanding their specific needs will ensure optimal performance. Begin by selecting a site with full sun exposure, meaning at least 6-8 hours of direct sunlight per day. Good air circulation is also beneficial to prevent fungal diseases. The ideal soil for this thornless blackberry plant is well-draining, loamy, and rich in organic matter, with a pH between 5.5 and 7.0. Before planting, amend heavy clay soils with compost or peat moss to improve drainage, or sandy soils to improve water retention.

Watering should be consistent, especially during dry periods and when the fruit is developing. Blackberries prefer consistently moist, but not waterlogged, soil. Deep watering once or twice a week is generally better than frequent shallow watering. Fertilize in early spring with a balanced slow-release fertilizer or an organic compost. Avoid over-fertilizing with nitrogen, which can lead to excessive cane growth at the expense of fruit production. Pruning is crucial for maximizing yield and plant health; ‘Columbia Star’ is a floricane-fruiting variety, meaning it produces fruit on second-year canes. After harvest, prune out the canes that have just fruited at ground level. New primocanes (first-year canes) should be tipped when they reach about 4-5 feet to encourage branching and future fruit production.

As a trailing variety, the Rubus ‘Columbia Star’ will benefit greatly from a trellis or support system. This keeps the canes off the ground, improves air circulation, makes harvesting easier, and prevents disease. Protect young plants from extreme cold in their first winter if planted in the lower end of USDA Zones 5-8 by mulching heavily around the base. Common problems include cane blight and anthracnose, which can often be mitigated by good air circulation and proper pruning. Watch out for pests like aphids and spider mites, and treat with horticultural oil or insecticidal soap if necessary. With proper care, your high-yielding blackberry will provide years of delicious fruit.
