In perennial fruit trees, most nutrient uptake occurs between bloom and rapid vegetative growth. Sweet cherry root growth starts when soil temperatures reach approximately 59 F during spring, usually after bloom in Washington soils. In sweet cherry, initial growth: bloom, pollen tube growth, spur leaf area, early shoot growth and early fruit development rely on reserves stored in roots, buds, and wood. Thus, fertilization of mobile nutrients should be programed accordingly to reduce losses. Here are some recommendations for sweet cherries grown in Eastern Washington.
