Planting European Asarabaca in the spring or fall, when temperatures are milder, is ideal. Sow seeds 1-2 cm (0.4-0.8 in) deep, 2-3 cm (0.8-1.2 in) apart, in a spot with consistent moisture. Transplant established seedlings 15-20 cm (6-8 in) apart, taking care not to damage roots.

Harvesting European Asarabaca's rhizomes can be done after 3-4 years, when plants reach 10-15 cm (4-6 in) in diameter. Dig carefully around the rhizome, then separate it from surrounding soil. Use a sharp knife to cut the rhizome into sections, taking care to preserve any attached roots.

Common pests affecting European Asarabaca include aphids, slugs, and snails. Root rot, powdery mildew, and leaf spot diseases can also occur. Regularly inspect plants for signs of infestation or infection, using integrated pest management techniques to control outbreaks and prevent damage.
