3. After 24 hours, sow the seeds and cover them with a light layer of soil.

4. Keep the substrate slightly damp, avoiding puddles of water.

5.Place the seeds where they receive the heat of the sun but not in direct sun. Try to keep the temperature between 15ºC to 19ºC; it can never be lower than 10ºC.

6. When the plant measures about 7.5 cm you can transplant it to its final pot or sow it directly in the garden. At this point, you can water the plant like an adult tree

Propagation by cutting:

Cut off a branch with a few leaves and soak the tip with a rooter.

Plant the cutting in a well-draining substrate. Just insert half the branch.

Keep the growing medium slightly damp, and occasionally add a small amount of the rooter after you’ve watered the plant.
