This situation makes it necessary to prune or remove the canes that have produced fruit. Roots develop shoot buds in fall and emerge in spring as floricanes. Fruit buds form in autumn under low temperatures and short day length. If this is followed by severe cold, plant injury or bud kill may result. Reducing the effects of fluctuating temperatures through cultivar and site selection or use of protective cover may be necessary to achieve consistent yield.
Yellow raspberries are similar in hardiness and root system as red raspberries.
Most fruit buds for June-bearing cultivars are between 1.5 and 4.5 feet from the ground. Reveille and Sentry may bear between 1.5 to 5.5 feet. The number of flowers is a function of cane vigor. Cane vigor is measured by floricane diameter. Generally, larger and taller canes produce more than shorter canes.
