You can also use cuttings for growing your herbs and spices. This is a slow method that produces smaller plants than seeds. You can easily divide cuttings using tools such as the pruner or a knife; before planting them in soil, place cuttings in water for a few days.

Finally, you can plant seeds directly in the soil and then cover them with soil until germination. Seeds are the best way to start plants from seeds. The seeds are cheap and easy to find, and they grow into healthy plants in only a few days.
