Hedge is a very common form of greening, which often plays the role of isolation and protection, noise isolation and covering up the shortcomings of greening. The hedges commonly used in gardens are: Buxus buxus, Ligustrum lucidum, Berberis amurensis, Sabina vulgaris, Platycladus orientalis, Hibiscus, Rose, Bamboo and other plants with strong germination, strong branching, strong healing, pruning resistance, strong shade tolerance and few pests and diseases. The construction of hedgerow has always been a very important link in the process of greening and conservation. The trimmed hedge can not only have better aesthetic effect, but also make the hedge grow stronger. Let's talk about the technical essentials of hedge pruning.

Hedge pruning period and times should be flexibly mastered according to different tree species. For the hedge of evergreen coniferous trees, because the new shoots germinate earlier every year, the first pruning should be completed in late spring and early summer, and cutting materials can be obtained. After beginning of autumn, autumn buds began to grow vigorously again. At this time, it is necessary to carry out a second comprehensive pruning to keep the plants neat and consistent in autumn and winter, and the wounds should be healed before the arrival of severe winter.

For most broad-leaved hedges, they can be pruned at any time as needed in spring, summer and autumn. In order to obtain enough cutting materials, it is usually carried out in late spring and early or late growing season. Hedges planted with flowering shrubs are unlikely to be pruned regularly, so it is better to prune them after the flowers wither, so as to avoid a large number of fruits and white shoots from consuming nutrients, promote the differentiation of new flower buds, and prepare for the coming year or later.

Types of hedges: According to different heights, hedges can be divided into green walls, high hedges, medium hedges and short hedges.
