What harm does hail do to apple trees?

The harm of hail to apple trees depends on the size, intensity and speed of hail falling. Hail occurs at different times, and the damage to fruit trees is also different. Hail in late spring mostly occurs in mid-April, which is the early stage of apple flowering. At this time, hail will smash the open petals, which has a great influence on fruit setting. Summer hail mostly occurs in early July, when the fruit is developing. At this time, light hail will damage the fruit and affect its external light quality. In addition, it will shoot down young fruits, resulting in a decline in yield, and may damage leaves, branches and branches, affecting photosynthesis and flower bud differentiation. Especially in the fruit expansion period, severe hail will destroy the whole garden, cause diseases and affect the results of the next year (figure 13).
