The spot where the container is to be placed must be open to sunlight and must be able to provide the necessary environmental factor needed by the plant.
Fill the container with growing mix:
Make an equal mix of cocopeat, perlite, and sand or add vermiculite to the growing pot. You can add compost to the potting mix so as to ensure that the media is as fertile as possible.
Make sure that the potting mix is not too compacted so as to ensure proper airflow within the soil profile and water the soil to keep it moist.
Plant the seed:
The seed should be planted at a depth of 1 – 2 inches so as to ensure the proper germination of the plant. Once the seed has been sown, cover the soil with potting mix and water carefully.
