Temperature Requirements
The Nigella orientalis is a hardy plant that can tolerate some frost. However, they thrive in warm temperatures ranging from 18°C to 25°C. In cold regions, it is best to start the seeds indoor under grow lights to ensure growth in spring.
Soil Requirements
Nigella orientalis prefers well-draining soil to avoid overwatering that can lead to root rot or fungal infections. The plant grows well in fertile and humus-rich soil with a pH ranging from 6.5 to 7.5. It is best to avoid clay soils, which tend to retain more water. Additionally, regular application of compost or organic fertilizers helps improve soil fertility hence better growth.
Cultivation methods
Nigella orientalis is a hardy annual plant that grows well in full sun or partial shade. It prefers well-draining soil that is rich in organic matter. Start the seeds indoors 6-8 weeks before the last spring frost or direct sow the seeds in the garden in early spring or fall. Cover the seeds with a thin layer of soil and keep the soil moist until germination occurs, which usually takes about 7-10 days. Thin seedlings to 8-12 inches apart to give them room to grow.
Watering needs
Nigella orientalis requires regular watering, especially during hot, dry weather. Water the plants deeply once or twice a week to keep the soil evenly moist but not waterlogged. Avoid overhead watering as it can lead to fungal diseases. Instead, water at the base of the plant to keep the leaves dry. Mulching around the base of the plant can help retain moisture in the soil and prevent weeds from growing.
Fertilization
Nigella orientalis does not require heavy fertilization as it prefers soils that are not too rich. However, you can apply a balanced, all-purpose fertilizer once a month during the growing season to encourage healthy growth and abundant flowering. Alternatively, you can amend the soil with compost or well-rotted manure before planting to provide the necessary nutrients.
Pruning
Nigella orientalis does not require much pruning, but you can deadhead the spent flowers to encourage new blooms. Pinching back the tips of the stems can also promote bushier growth and prevent the plants from getting too leggy. If the plants become overcrowded or begin to flop over, you can divide them in the fall to rejuvenate them or provide support with stakes or cages.

Cuttings
Nigella orientalis is not typically propagated through cuttings as the plant may not root successfully. However, if cutting propagation is the preferred method, take cuttings in the early morning from the tip of a healthy stem. Dip the end of the cutting in rooting hormone powder and then plant into a well-draining potting mixture. Keep the cutting moist and warm until roots develop, which can take up to 4-6 weeks.
Division
Nigella orientalis can be divided in the early spring before the plant begins to put out new growth. Take a sharp knife and cut through the plant's root system into the desired sections. Ensure that each section has some roots and plant it into a well-draining potting mixture. Keep the soil consistently moist and warm, and roots should start to develop within 2-4 weeks.
