Grow them in the sunniest location you have or under fluorescent lights. Avoid overwatering which will cause the roots to rot. Check the plants frequently for aphids, spider mites, and whiteflies which are common pests on herbs grown indoors. The seeds of the more common herbs, such as dill, basil, and parsley are usually available from local seed dealers, while the less common ones should be purchaed from companies specializing in herbs. For a listing of some recommended sources of herb seeds and plants, see Fact Sheet VC-32, Sources of Herbs.
Biennial herbs grow for two seasons, flowering the second year only.
Perennial herbs, once established, overwinter and flower each season. Your herb garden will need attention throughout the growing season. Weed control and provision for adequate moisture are two important cultural necessities. When rainfall is less than 1 inch per week, provide additional moisture. The use of a mulch is an attractive and effective means of controlling weeks and maintaining constant soil moisture and temperature for the root systems of your herbs.
