Whether you are a seasoned grower or a beginner, this variety is a fantastic addition to any fruit garden.

Finding the Perfect Spot

For the best growth and fruiting, plant Blackberry ‘Chester’ in a sunny position with well-drained, fertile soil. A sheltered location will help protect it from strong winds, leading to healthier plants and improved yields. While this variety is self-fertile, planting in a pollinator-friendly environment can further boost fruit production.
