Rosemary prefers to live outside but can last the winter indoors. Bright light and good drainage are musts. Allow plants to dry out slightly between waterings, and don't let them stand in saucers of water. Good air circulation and cool nights lessen pest problems. Move them outside as soon as all chance of frost has passed. Feed once in late spring with a controlled-released fertilizer such as Osmocote.
