Growing Tips & Guides

Get Started

Rubus spp.

Cultivated for centuries, blackberries are prized for their deep purple, glossy fruit that's so sweet and tasty. Packed with a high level of antioxidants, bioflavonoids and Vitamin C. We think our gardeners will love the fruit and appreciate the plants' vigor, productivity and ease of cultivation.

Initial Instructions
After unpacking, allow the plant a few days to gradually acclimate to its full exposure. Plant your blackberry in an area with well-drained, not soggy soil that’s enriched with humus. Initially, apply ½ cup of Territorial’s Complete Fertilizer per plant mixed into the bottom of the planting hole, backfill around the plant and water well. Blackberries appreciate a minimum of ½ day of sun to full sun for best production.

Cultivation
Blackberries are generally vigorous growers and require support to hold up the plants. A trellis or fence at least 4-5 feet tall should provide adequate support. Our blackberries produces fruit on the 2nd year old canes. After fruiting, the cane will die, and you can prune it back to the ground. In spring, prune the canes to about 5 feet tall to encourage lateral branching and produce more fruit. Keep the soil moist for the first year to establish the plant.
