1、 How to trim

1. Pruning time: the pruning time of columbine is usually in its peak growth season. At this time, the climate is warm and the plant grows rapidly, which is conducive to recovery after pruning. If in the dormancy period, the growth of the second year is often affected due to the lack of nutrients after cutting

2. Pruning method: due to the fast growth rate of columbine, it is very easy to become lush. In this way, it is easy to affect the internal ventilation and light transmission, which is not conducive to plant growth, and may also cause diseases and pests. Therefore, pruning is mainly sparse pruning, so as to provide enough growth space for new branches

3. Post cutting care: after trimming the Columbine, ventilation should be done to reduce the humidity of the environment to avoid wound infection. In addition, it should be properly fertilized to supplement nutrients, accelerate the growth of the plant and make it recover faster

2、 How to breed

1. Ramet method: columbine can be propagated by ramet method. The ramet time is usually in spring and autumn, from March to April in spring and from August to September in autumn. After the plant is detached from the flowerpot, it can be divided into several clusters and planted separately

2. Sowing method: columbine can also sow and reproduce. The time is mostly in spring and autumn. After sowing with a pot, cover with vermiculite, control the temperature between 21-24 ℃, and sprout after 10-14 days. After that, apply nitrogen fertilizer once a week to maintain long-term sunshine
