1、 Class II pruning

Clematis can be pruned in three ways according to different varieties. The second kind of pruning refers to light pruning in winter, which is often applicable to large flower varieties that bloom in spring. Evergreen and long petal are more suitable for one kind of pruning. They don't prune in spring, or just cut off dead branches. Late flowers are more suitable for three types of pruning. They should be re cut in spring, and most of the branches and leaves should be cut off

2、 Pruning time

The second kind of pruning time is in the late winter and early spring. In the warmer areas in the south, pruning can be carried out a little earlier, and in the Guangdong and Guangxi regions, pruning can be carried out in early December. In the north, it is cold in winter, so it needs to wait until the end of January to the beginning of February. Pruning too early is easy to break its dormancy. If it encounters low temperature, it will frostbite the plant

3、 How to trim

The second kind of pruning should not be too heavy, and the original structure cannot be damaged. Only the excessively long branches need to be cut short. Generally, you should count down from the top and leave it from the first strong bud. Cut at 3-4cm on the bud and keep 7-10 branches. In addition, the over dense branches should be thinly cut, and the dead branches and weak branches should be cut off
