When planting and pruning seedlings, there are often too simple and rigid problems. For example, when planting deciduous trees, a certain trunk height is usually reserved for trunk cutting; When planting shrubs, adopt the practice of "pushing the crown flat", that is, all branches are cut short at the same height; When planting evergreen trees, they are basically not trimmed. These simple pruning without considering tree species, planting methods, planting seasons and other factors are unfavorable to the survival and shaping of seedlings. Therefore, when planting and pruning seedlings, we should comprehensively consider various factors and carry out reasonable pruning.
