Abstract:The growth of plants is not static,and we should pay special attention to the dynamics of plants.The maintenance methods of different plants in different growth periods(such as pruning of Lagerstroemia indica and pruning of Photinia fraseri)should not be ignored.As a multi-dimensional art,plant landscape contains different characteristics such as appearance,color,smell,touch,etc.At the same time,it is deeply influenced by the uncertain factor of time.According to the growth and development differences of plants in different periods,the planting structure should be reasonably arranged,seasonal matching should be strengthened,the viewing period should be prolonged,and the viewing angle should be increased.
