Coriandrum sativum, commonly known as coriander or cilantro, is an annual herb in the family Apiaceae. It is native to regions spanning from Southern Europe and Northern Africa to Southwestern Asia. The plant is known for its aromatic leaves and seeds, which are used in various culinary dishes. It thrives in subtropical climates and has a relatively short life cycle.
Coriander requires bright, direct sunlight for optimal growth. It prefers moderate temperatures and moderate humidity levels. Regular watering is essential, but the soil should be allowed to dry out partially between waterings. The plant can be grown both indoors and outdoors, making it versatile for different growing conditions.
収穫
Coriandrum sativum, commonly known as cilantro or coriander, should be harvested when the leaves are bright green and before the plant starts to flower, typically around 60 days after planting. To harvest, cut the stems about one-third of the way down, ensuring not to uproot the plant. For coriander seeds, allow the plant to flower and form seeds, then harvest the seeds when they turn brown and dry. Ensure to harvest in the morning when the essential oils are at their peak for the best flavor.
土壌
Coriander prefers well-draining loamy soil with a slightly acidic to neutral pH. Good drainage is crucial to prevent root rot. A soil mix that retains some moisture but does not stay waterlogged is ideal for this plant.
肥料
A balanced fertilizer with a nutrient composition of 5-10-5 (N-P-K) is suitable for coriander. Fertilize the plant every few weeks during the growing season to ensure healthy growth and development.
植え替え
Coriander can be repotted if necessary, especially if it outgrows its current container. Repotting should be done carefully to avoid damaging the roots. It is best to repot during the early stages of growth.
伝搬
Coriander is typically propagated from seeds. Sow the seeds directly into the soil in early spring or late summer. Ensure the soil is kept moist until germination occurs. Thin the seedlings to allow adequate space for growth.
剪定
Pruning is beneficial for coriander to encourage bushier growth and prevent the plant from bolting. Regularly trim the leaves and stems, especially if the plant starts to flower prematurely.
毒性
Coriander is not toxic to pets or humans. Both the leaves and seeds are commonly used in cooking and are safe for consumption.
