The Climax Blueberry is a blueberry bush that produces fruit early in the season with a high yield of large, dark blueberries. Blueberries grow best in full sun. Plants will tolerate partial shade, but too much shade causes plants to produce fewer blossoms and less fruit. Avoid areas surrounded by trees. Trees provide too much shade, compete with plants for water and nutrients, and interfere with air movement around plants.Generally reaches 6-8 ft. tall.
