Ramets: Both spring and autumn can be carried out. In spring, the new shoots will grow to 15-18cm, and the cuttings will be transplanted after rooting. You can also take new cuttings at the base after flowering.

Delphinium cuttings: propagation is carried out in spring, when the new principal is over 15cm, the cuttings are cut and inserted into the sand.

Sowing: mostly in March-April or September, the optimum temperature for germination is about 15°C. Autumn sowing is from late August to early September, first sown into the open seedbed, and enter the cold bed or cold room for overwintering before the winter.Planting in warm spring. Early spring in the south and open field in the south, keeping the spacing between 25-50cm. In the north, the seedlings are usually raised in advance and planted in April, transplanting 2 to 4 true leaves, and 4 to 7 true leaves for planting. Pay attention to drainage on rainy days.Before planting, apply sufficient base fertilizer, and topdressing is mainly nitrogen fertilizer. The growth potential of old plants is weak and needs to be transplanted once in 2-3 years. The plants are tall, easy to fall or bend, and need to be supported and fixed.
