The propagation method of Angelica dahurica is mainly through seed sowing, and it is best to sow seeds in the same year. If you choose aged seeds to sow, the germination rate is low, and there is a great chance that they will not germinate. The seeds of Angelica dahurica are ripe in July every year, when the seeds are harvested and dried, impurities are removed and the seeds can be sown. Sowing can be chosen as spring sowing or autumn sowing, and sowing can be divided into sowing, strip sowing or hole sowing.

When the seedlings grow to 5-6cm, it is necessary to carry out inter-seedlings, properly remove some weak seedlings and cultivate strong seedlings, which can evenly distribute the seedlings and increase the ventilation and light transmittance of the plants. When the seedlings grow to about 15cm, they can begin to colonize, leaving 1-2 strong seedlings per hole, pay attention to remove diseased seedlings or weak seedlings, and remove those whose stems have appeared blue and white, so as to reduce the occurrence of Angelica dahurica.

The weeds should be removed by hand when the seedlings are below 5cm for the first time, so as not to damage the roots. If the soil is hardened, the soil can be ploughed 2-3cm; the second time, when the seedlings grow 6-10cm, they can be ploughed a little deeper; the third time, when the seedlings are fixed, the weeds should be removed when the soil is loosened.
