|'Avonblue' ripens early in the season. It is subject to overbearing and needs to be pruned to balance the fruit load as well as the young plants must be defruited to obtain good growth. 'Avonblue' blooms a week after the cultivar, 'Sharpblue'. The temperature should be 45 F or below to satisfy bud rest and to allow the flowers to open and develop normally.
This deciduous shrub is dense with an upright, multiple-branched growth habit. Leaves are elliptical, and can be toothed or entire, to 3 inches long, turning red or yellow in the fall. White, sometimes pink tinged flowers to 1/2 inch across are held in pendant terminal racemes. Flowers are followed by edible, sweet, round, deep blue berries to 1/2 inch across.
Many varieties are available, check for the ones that are best suited to your local area. Blueberries love acid soil.
