Sowing and propagation of columbine

Sowing should be sparse. Before seeds emerge, the sowing basin needs to be covered with glass to keep the soil moist and shaded. Seedling emergence in 1 month. The seedlings bloom in the second year. High quality varieties are generally propagated by ramet method, which is carried out in March ~ April or August ~ September, but autumn is better. The seedlings can be planted after about 10cm, and the row spacing of plants is 30 ~ 40cm. Topdressing should be applied once before flowering. Shade is needed in summer. Cold areas need a little coverage in winter. Plants are easy to decline after 3 years, so they should be divided in time to promote their renewal

Ramet propagation of columbine

Fertilization and land preparation are the same as above. Plant in spring or autumn, from January to April in spring and from August to December in autumn, with a row spacing of 10 × 13.2cm, cover 1.6cm of soil, pour enough water, and keep the soil moist during the growth period. During the vigorous growth period, apply a small amount of urea, 5kg per mu. After mixing with water, irrigate the plant to promote its growth. Seed reproduction: seeds can be sown from January to April in spring and from June to December in autumn< span>

Breeding precautions of columbine

When sown in spring and autumn, the sown seedlings can bloom in about 2 years. The fixed planting seedlings need to be renewed once every 3 ~ 4 years. Cold resistant, strong growth potential, like wet and well drained sandy loam. I like the half shade environment. Ramets should be carried out before germination or after defoliation in early spring. It is best to sow in pots immediately after the seeds are mature
