Different pruning methods should be adopted for different garden configurations: (1) Shrubby: this cultivation form is simple and extensive in maintenance and management, and is suitable for application in remote places in parks.
Let its clustered branches develop naturally, and focus on protected areas to spread branches and spread branches.
But be careful not to leave too many branches, which will cause poor permeability.
Tamarix chinensis is extremely resistant to pruning, and can remove dead branches, pests and diseases in the spring and summer growth period, which is conducive to ventilation and light transmission and promotes the formation of dense and plump natural shrubs.
Update old branches in time, so that shrubs can maintain good ornamental effect for a long time.
(2) Small tree shape: This cultivation form is suitable for solitary planting, and can also be planted into a Tamarix forest.
Select the upright and stout branches as the trunk culture, keep the trunk 30 ~ 50 cm high and cut it short, and remove the useless branches on the trunk and the sprouting and long branches in the rhizosphere in time.
Select the vertical branches extracted from the trunk as the extension branches of the trunk, carry out medium trunk culture, and select more than two branches with suitable distribution as the trunk.
Cut short the main branch, select and leave the side branch in the appropriate position.
After several years of repeated pruning, it can form the shape of a small tree.
(3) Hedgerow: Shrubby Tamarix ramosissima is mainly planted in one or more rows in a straight line or curve, which is used on both sides of expressway, flower beds and lawns. It has smooth linear beauty and colorful flowers, and its bright red branches are also a beautiful scenery in winter and spring.

Before germination in spring or after defoliation in autumn, the old Tamarix hedge can be renewed, leaving only 0.3 ~ 0.4 meters high to cut dry. At the same time, maintenance measures such as loosening soil, weeding, watering and fertilization should be taken to control the excessive growth and irregular growth of branches in time.
