Growing culinary herbs indoors is an easy and inexpensive way to enjoy their fresh taste year-round. 6 hours of direct, bright light or 12-14 hours of artificial light is the first requirement. Watering will vary by herb, so check the plant tag and be sure to use plant containers with drainage holes. A liquid houseplant food at half the recommended rate can help keep indoors herbs vigorous. Regular pruning of tips, for seasoning meals or just to keep things tidy, will also encourage dense, healthy growth.
