As shoots develop, two types of buds are formed at each node in the leaf axil at the base of the petiole. Lateral, or prompt, buds are formed first. Prompt buds are so named because lateral shoots arise from them in the season the buds are formed; these shoots are also referred to as summer laterals. Lateral shoots may be very short or quite long. Most of the short lateral shoots fail to lignify and drop from canes during dormancy.
