The publication covers tactics to manage powdery mildew, including use of fungicides and canopy management. While rabbiteye blueberry blooms relatively late, southern highbush blooms early in late winter or spring, after chilling is satisfied, making these poorly adapted to the Pacific Northwest. This wood has vegetative buds (small, scale-like buds that will only produce a shoot with leaves). This small, black tip is referred to as the “black tip” stage.

Leaf analysis is used to determine the element associated with a nutrient disorder and to prescribe a corrective measure and to estimate fertilizer needs before nutrient disorders occur. Inorganic salts, chlorophyll (the green pigment in plants) and other catalysts are important in this process. The first is bud initiation in the autumn. If a plant is not pruned well, there is too much fruit (the strongest “sink”) on it, then the growth of the shoots and roots will suffer, and the plant will not store as many carbohydrates and nutrients as it would if it were “balance” pruned. All the different growth stages have names that describe them (see the Blueberry Growth Stages table).

After pollination and fruit set, the berry goes through three phases of growth: The development of pink and then blue color starts at the end of the second phase of berry growth. The number of flower buds per shoot is related to the number of days of good weather. In the plant, there is a flow of carbohydrates from the “source” of production (leaves) or a storage source (roots, crown and older canes) to a depository known as the “sink” (fruit, shoot tips and root tips).
