Answer: Rosemary can be very difficult as a houseplant. The soil needs to be kept evenly and lightly moist but not sopping wet. The frequency will depend on how warm and humid the room is, and how much air circulation there is, the type of potting soil used and whether or not the pot is porous so you will need to check the soil with your finger and see. Indoors, the plant does best in a cool, bright location with both ample humidity and good air ciculation. During the winter when the plants slow down they should not need much fertilizer, if any. During spring and summer however, fertilize lightly with a water soluble fertilizer for foliage plants according to the label instructions. They will also need more water during the times they are in active growth.
