Growing Lawsonia inermis from seeds can be a rewarding process. Here’s a step-by-step guide to help you grow henna from seeds:

  • Obtain fresh henna seeds from a reputable source or collect them from mature henna plants.
  • Soak the henna seeds in warm water overnight to soften the hard outer shell and promote germination. This step is optional but can enhance the germination rate.
  • Prepare a well-draining potting mix. A mixture of equal parts sand, loam, peat moss, or coco coir works well.
  • Fill small pots or seed trays with the potting mix, leaving some space at the top for watering.
  • Plant the henna seeds about half an inch deep into the soil. Sow one or two seeds per pot or evenly in the tray.
  • Press the seeds into the soil and cover them lightly with the potting mix. After sowing the seeds, thoroughly water the pots or trays to ensure moist soil.
  • Place the pots or trays in a warm and bright location. Henna seeds typically germinate within 1 to 3 weeks, but it can take longer, so be patient.
  • Once the henna seedlings have developed a few sets of true leaves and are sturdy enough to handle, they can be transplanted into individual pots.
