お手入れ方法
Woad prefers temperate climates and should be grown in areas with full sun exposure. It thrives in moderate temperatures and requires well-drained soil. Water the plant when the soil is almost dry, and ensure it has good air circulation to prevent fungal diseases.土壌
Woad grows best in well-drained loamy soil. It can tolerate a range of soil types but prefers soil that is not too rich in nutrients. Ensure the soil has good drainage to prevent waterlogging, which can harm the plant.肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant once a month during the growing season to support its growth and development.植え替え
Repot woad if it outgrows its container or if the soil becomes depleted. The best time to repot is in early spring before the growing season begins. Use a well-draining potting mix and a container with drainage holes.伝搬
Woad can be propagated by seeds. Sow the seeds in early spring directly into the ground or in seed trays. Thin the seedlings to allow enough space for growth. Ensure the soil is kept moist until the seeds germinate.剪定
Prune woad to remove dead or damaged leaves and to control its size. Pruning can be done in late winter or early spring before new growth starts. Regular pruning helps maintain the plant's shape and encourages healthy growth.毒性
Woad is not toxic to pets or humans. However, as with any plant, it is best to avoid ingestion of large quantities of any part of the plant.追加
