Golden columbine is mostly perennial plants and can generally live for 4 to 5 years, with some species only living for 1 to 2 years. We can propagate it by sowing or transplanting in general. Since the seeds of golden columbine have a short shelf life, they should be sown in the year of collection. Prepare slightly moistened sandy soil before sowing, spread the seeds evenly and press the soil gently and cover it with a layer of glass instead of a layer of fine soil and then place it in a shady environment with a temperature at about 18 to 24 ℃ for germination.
It takes relatively long time for seeds to germinate, which is about 2 to 4 weeks, and it may take a few seeds several months to break the dormancy and finally germinate. In general, seeds of golden columbine do not need to be exposed to low temperature to promote germination, but if the seeds do not germinate after a long time, they can be stored at a low temperature environment of -4 to 4 ℃ for 2 to 4 weeks to break the dormancy, and then they can be taken out again for sowing. Seeds that are not used for the time being can also be stored in a refrigerator at low temperature until the next sowing season.
Golden columbine has a strong ability of self-seeding and can spread naturally without being sown, so you can also transplant the seedlings and place them where you want them. Its root cap should be flush with the soil surface and all the fragile and fine roots should all be buried in the soil when transplanting.
As the root system of golden columbine is relatively fragile, which is not very suitable for division propagation, so if you have to divide a plant, you need to dig out the whole plant and use a sharp knife to divide the whole root system into several clumps and plant them separately as soon as possible without shaking off the root soil. It is better to divide plants in spring and support them with plant stakes when the plant grows higher.
