Start growing your thyme indoors. Starting thyme outdoors is perfectly acceptable, but to speed the process up, start 15 to 20 seeds in a small pot indoors.
Choose your location. If you're going to plant your thyme outdoors, choose a spot with full sun exposure. If you're planting indoors, make sure you choose a location in front of a window with a southern exposure, to give the plants the most light possible.
Prepare your soil. Thyme thrives in light, relatively dry soils; so mix sand or another soil amendment in with your regular soil to maximize the growing conditions.
Plant your thyme seedlings. Leave 8 to 12 inches between the seedlings, since thyme can grow to be fairly large when growing conditions are maximized.
Water your seedlings, but don't overwater them. Thyme does not require a lot of water and will thrive in arid conditions. Water once per week in drought conditions.
