Cultivation
It can be grown from seed and is sown from April through May in the Northern Hemisphere. The seeds can be planted in a set bed or a temporary nursery bed and then transplanted to the growing site. They should be spread 30 cm apart each way. The young (edible) leaves are ready about 4–5 weeks after planting and the edible stems are ready when about 30 cm tall. They are usually harvested between July and September.
The plant can suffer from aphid attacks.
