Woad is one of the few plants that can be used as a natural blue dye besides real indigo. The dying process is simple and has been implemented since prehistoric times. The plant blooms bright yellow in May of the second year after overwintering. Height reaches 150 cm.
Sow from March to April in nutrient-rich soil in rows 50 cm apart. Germination is slow, so sowing in seedling trays is recommended. Thin out rows or transplant to 30 cm spacing. In the first year, it forms a strong rosette of leaves. Once the lower leaves begin to wither, cut the whole leafy-bush to use for colour extraction. Two to three harvests are possible.
