What are the principles of tree shaping and pruning in ecological gardens?
1 shaping and pruning according to the use of trees in gardens
The response of different shaping and pruning measures will be different; the use of trees in the garden is different, the requirements of shaping and pruning are also different. For example, when the cypress is planted alone, it maintains the natural tree shape, while the hedge is often re-cut into a regular tree shape.
2 shaping and pruning according to the biological characteristics of tree species
2.1 growth and development characteristics of tree species. The growth and development characteristics of different tree species are different, so it is necessary to adopt corresponding shaping and pruning methods. Strong branching and weight-resistant pruning can be pruned many times. Trees with weak branching ability should be pruned lightly. Trees that bloom in spring and bud in annual branches or leaf axils should be pruned during dormancy. Trees with terminal flower buds should not be truncated during dormancy or before flowering.
2.2 the age of tree species. Young trees should be cut weakly so as not to reduce cold resistance and delay flowering. Adult trees have the best viewing period and the strongest resistance to adversity, so it is appropriate to comprehensively use various pruning methods to adjust the relationship between flowering and fruiting and growth. The aging trees are mainly cut by strong cutting to renew and rejuvenate.
3 shaping and pruning according to the site environment of tree species
The growth and development of trees is closely related to environmental conditions, even if the purpose of landscaping is the same and the site conditions are different, the methods of pruning and shaping are also different. If planting trees alone, it is usually natural, but in windy places, the height of the trunk should be reduced to make the crown sparse.
