If you sow nigella black seed in almost any sunny location, with almost any type of soil, you will soon see the fruits of your labor. However, for the best results your planting bed should be prepared as per the instructions in this article to ensure that you have the best possible crop of this beautiful flowering plant and can harvest the greatest amount of nigella black seed, which is used extensively in food preparation, especially in preparing Indian dishes. Plant seeds in the spring and expect to harvest your new seeds in the fall.
Place your nigella black seeds in a baggie and place in the refrigerator for one week before planting. Remove from the refrigerator and allow to sit in a warm place out of direct sun for 24 hours just before planting.
Choose a sunny location as nigella prefers full sun.Turn the soil in your garden at least 6 inches deep with your spade. Break up dirt clods, remove rocks and other debris.
Spread a liberal amount of humus into the bed you have just turned and rake the humus into the top 2 inches of soil. Use a rake to level the bed.
Spread your nigella black seeds evenly over the top of the bedding soil. Seeds should be 2 to 3 inches apart.
Sprinkle a thin layer of humus over the top of the seeds, just barely covering them.
Place a brick at each corner of the garden. Spread a sheet of plastic over the garden and then place another brick on top of each of the first bricks, creating a brick/plastic sheet/brick "sandwich." Pull the plastic taught and hold it taught with the bricks to form a sort of mini-greenhouse that will keep birds and small animals away.
Wait until the nigella plants are at least an inch to an 1 1/2-inches tall before removing the plastic sheet.
