Grow Rubus fruticosus 'Chester' for dependable, late-season blackberry harvests and easy picking from thornless, semi-erect canes. You will enjoy clusters of pinkish-white spring flowers followed by very large, glossy black berries with a sweet, classic blackberry flavor. This variety is often grown on a simple trellis or wire support to keep canes upright and improve airflow.
Plant it where you can give it full sun for best flowering and fruiting, though it will tolerate part shade. Choose well-drained soil and water regularly during establishment and during dry spells, especially while fruit is sizing up. Mulch to conserve moisture and reduce competition around the root zone.
Prune with blackberry cane habits in mind. After harvest, remove spent fruiting canes (floricanes) at ground level. In summer, tip vigorous new canes (primocanes) to encourage branching and keep the patch manageable. With basic support and yearly pruning, 'Chester' can produce heavy yields for many seasons while reaching roughly 48-72 inches in height and spreading as new canes arise from the crown.
