Nigella sativa, commonly known as black cumin, black seed, or kalonji, is an annual flowering plant in the family Ranunculaceae, native to the Mediterranean region. It is known for its culinary and medicinal uses, with seeds that are often used as a spice. The plant has delicate, feathery foliage and pale blue to white flowers.
Nigella sativa prefers full sun and moderate temperatures. It should be watered when the soil is dry, but it is drought-tolerant once established. The plant thrives in temperate climates and does not require high humidity. It is relatively easy to care for and can be grown outdoors in suitable climates.
収穫
Nigella sativa, commonly known as black cumin, is typically ready for harvest about 90 days after planting. The plant is harvested when the seed pods turn brown and start to dry out. To harvest, cut the stems and hang them upside down in a dry, well-ventilated area to allow the pods to fully dry. Once dried, the seeds can be extracted by gently crushing the pods and separating the seeds from the chaff. It is important to ensure that the seeds are completely dry before storage to prevent mold and spoilage.
土壌
Nigella sativa prefers well-draining loamy soil with a slightly acidic to neutral pH. It can tolerate poor soil conditions but performs best in moderately fertile soil. Ensure good drainage to prevent waterlogging.
肥料
A balanced fertilizer with a nutrient composition of 5-10-10 can be applied once during the growing season to promote healthy growth and flowering. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
植え替え
As an annual plant, Nigella sativa does not require repotting. It is typically grown from seed each year. If growing in containers, ensure the pot has good drainage and is large enough to accommodate the plant's root system.
伝搬
Nigella sativa is easily propagated from seeds. Sow seeds directly in the garden or in containers in early spring after the last frost. Seeds can also be started indoors 4-6 weeks before the last frost date and transplanted outdoors once the weather warms up.
剪定
Pruning is not necessary for Nigella sativa. However, deadheading spent flowers can encourage additional blooming and prevent self-seeding if desired.
毒性
Nigella sativa is not toxic to pets or humans. The seeds are commonly used in cooking and have various medicinal properties. However, as with any plant, it is best to avoid excessive consumption.
追加
Nigella sativa is known for its seeds, which have been used for centuries in traditional medicine and cooking. The seeds are often referred to as 'black seed' and are believed to have various health benefits, including anti-inflammatory and antioxidant properties.
