Purchase a variety of garlic chive seeds from any home improvement store or a local nursery. Garlic chives are grown from seeds and not from cuttings.
Prepare a pot with a mixture of good quality potting soil. The pot should be at least 18 inches in diameter and over 12 inches deep.
Germinate garlic chive seeds by planting each seed about ½-inch deep in flats or right into the potting soil. Keep soil temperature to a warm 60 to 70 degree F level for the first 4 to 6 weeks.
Move the garlic chive plants from the flat, and plant as usual outdoors or into the waiting pot, if needed. Water two or three times a week. Garlic chives are very forgiving when it comes to watering, but be diligent to prevent them from completely drying out.
Harvest the leaves once they reach a height of 6 inches. Cut the leaves with a sharp implement to prevent tearing of the leaf.
