Also, the planting methods may vary depending on the instructions on the label of the seed packet.

Prepare your seedling tray and potting mix. Fill the tray with a potting soil. The tray does not need to be large. The soil should be fertile, light, and well-draining. Using a water spray, moisten the soil and sow the seeds. Plant it at a depth of about half an inch. Alternatively, you can also plant it in a larger pot and not a seedling tray, if you prefer. Within five to ten days, the seeds will begin to germinate. If you start from a small tray, you can now transfer it to a larger container.
