A very unique herbaceous plant is Nigella sativa , also known by the common names of black cumin, absinthe or ajenuz. It belongs to the Ranunculaceae family , reaches a maximum of 60 centimeters in height and its appearance is grayish green and has an unconventional whitish or slightly purple flower with sepals larger or more striking than the petals.

In the case of sowing and multiplication of Nigella sativa, this must be done with seeds, which appear after flowering is a fact, at the end of spring.

The seeds come inside a pod and are very aromatic , similar in smell to nutmeg. That is why they are also called false cumin. These are removed by leaving the sheathed capsule to dry, which protects them from the elements.

The appropriate thing is to cultivate them in seedbeds, when the winter season arrives and then move them to the ground, to the garden where they can fully develop until they reach a height of between 30 to 40 centimeters, or perhaps a little more.


Did you know…?
A curious fact about this seed is that it was used even in the tombs of the Pharaohs in Ancient Egypt and Cleopatra used its essential oil to keep its beauty intact.

Its growth cycle is quite fast, because it takes 10-11 months to germinate, grow and give away thousands of seeds for use in the kitchen and for medicinal purposes.

How do we prepare the land?

The earth must have a fundamental characteristic: alkaline soil is the most suitable for black cumin. An alkaline pH suits him very well, but acidic or neutral pH soils still suit him, so much so that this plant can still grow in sandy and clay soils.

A high-drainage soil is very important for this herbaceous, because its roots are actually somewhat delicate and do not support excessive humidity, so the waterings must be carried out in a spaced manner with great care not to drown it.

A preparation of organic nutrients will help it a lot to grow healthily, since it favors the growth of strong roots, as well as the production of its essential oils of high commercial value.

How to sow Nigella Sativa step by step?

If you can buy or access some black cumin seeds, we recommend the following tips to take advantage of its benefits:

  1. Prepare a potted substrate universal culture containing 35% perlite to ensure good drainage of water.
  2. If you prefer to plant them in a garden, remember that Nigella sativa is not very demanding, but it avoids puddles. That is why very porous soils favor it.
  3. It is recommended, once the seeds have been sown at an estimated depth of about 4 centimeters, taking care of a distance between seed and seed of about 5 centimeters. Ideally, do this in spring, in seedbeds or directly in the garden .
  4. It is necessary to water 3-4 times a week in the summer season, because both the plant and the seed need to stay hydrated and the rest of the year it can decrease to 2 times a week.
  5. Likewise, the application of a powerful organic fertilizer is recommended to keep it well nourished. The guano is ideal to help.
  6. Pruning withered leaves and flowers is essential to maintain the health of the plant.

  • It is advisable to lavish a good extra dose of fertilizer in the flowering season, between spring and early summer.

What pests and diseases does it have?

It does not usually suffer serious problems with bug attacks but it is affected tremendously when it is subjected to intensive irrigation, because its roots will tend to rot and the flowering cycle will be impaired.
