  3. In a pot, place clay or gravel at the bottom. Add universal substrate until ¾ of the remaining height of the pot is reached.
  4. Carefully place the cutting and fix it to the center of the area.
  5. Cover with a light layer of substrate, gently seat it with your fingers and water until the water runs out of the holes in the pot.
  6. Locate the pot out of direct sunlight and keep the soil slightly moist until new leaves begin to sprout.
