Chives should be grown in a sunny location in well drained soil, however these herbs also make an excellent pot herb. They can be grown from seed (planted early in the spring, after the frost is finished), from starts (purchased from a nursery and put into the ground after the danger of frost is done), or from roots taken from an established plant (planted like starts). Chives grown in pots can be started at any point in the year if you intend to keep them inside.
