Angelica sinensis grows both in mountainous wetlands and on coastal areas.
It is cultivated in Asia for medicinal purposes for the countless uses of local medicine.
The right time to grow angelica is late winter, early spring. Angelica seeds must first be sown in a greenhouse and then subsequently transplanted in the open field. The transplant must be carried out in the early spring in the open field.
It is a plant that bears very well low temperatures and harsh winters but the optimal conditions are those of a cool and humid climate.
The substrate must be moist, rich in organic substances and well drained. Before cultivation it is good to intervene with mature manure.
In transplanting, rows of seedlings should be arranged at a distance of 60-70 cm.
Watering must be regular to leave the soil moist.
The angelic plant blooms in the June-August period.
The fresh leaves can be taken at the beginning of the spring; the fruits are harvested around June before flowering.
As for the care of the plant, we recommend every 15 days to eliminate all the herbs that grow around the plant.
Be careful in the collection of spontaneous species, since being a plant very similar to the poisonous plant of the Cicuta, before touching and using it make sure that it is Angelica and not the latter.
