Green Columbines can be propagated by sowing and division. Both methods are easy to operate. Let's look at sowing and division propagation methods of Green Columbines respectively.
The best time to apply the sowing propagation method of Green columbine is immediately after the harvest of the mature seeds. It is generally possible to plant the Green columbine in a pot. After sowing, a thin layer of soil should be covered, and then water should be used to keep the seeds moist.
Seeds usually emerge about a month after sowing.
Green Columbine can be divided in March to April or August to September, but it is better to divide in autumn. Remove the Green columbine mother plant from the pot and straighten out the root system. Separate the small Green columbine plants and plant them in pots.
Then put it in a ventilated place for a period of time, and then gradually give light after a few days. In addition, shade treatment is needed in summer. In such areas, slightly more coverage is needed in colder places. Generally, Green columbine is prone to decline after 3 years, so it needs timely treatment for plant splitter.
