‘Columbia Giant’ Blackberry (Rubus fruticosus ‘Columbia Giant’). The Rubus fruticosus ‘Columbia Giant’ is an exceptionally productive, thornless blackberry known for the impressive size of its fruit. This fruit bush with a sprawling, bushy habit develops long, vigorous canes ideal for trellis or structured row cultivation. It produces very large, shiny black, elongated, firm, juicy, and richly sweet fruits, perfect for fresh consumption, baking, and processing. Its summer fruiting, on previous year's canes, ensures an abundant mid-season harvest.

To plant the ‘Columbia Giant’ blackberry, choose a suitable exposure: full sun. The recommended soil is: rich, well-drained, slightly acidic. Ensure access for picking fruit without breaking new canes. Pruning depends on the fruiting cycle: distinguish canes that have produced shoots for the next harvest. Support can facilitate the maintenance of vigorous varieties. Water the root ball before planting it in the ground and ensure that water can drain after planting. During recovery, check the moisture by hand before watering again.

Allow a width of 2 m (7 ft) to plan the placement of this plant in the garden. The indicated height of 2 m (7 ft) helps choose its position relative to neighboring plants. Keep access to the base for weeding, checking moisture, and removing damaged parts. Associate this variety with plants whose light and water needs are compatible. If you are considering a container, first check that its volume and drainage are suitable for root development. Roots in pots are more exposed to cold than those planted in the ground.
