Slake has pretty well touched all the bases.
You can, btw, grow basil very successfully indoors. Rather than depending on window sunlight, however, you'd do better by growing it under lights. Don't drop big bucks on those fancy grow-lights, though. Regular, cold-bulb floruescents will do just fine.
About once a month, add a fish emulsion or other high-nitrogen fertilizer. That will promote leaf growth. Other than that, make sure the plant has plenty of root room, and water when the soil surface turns dry.
Basil, grown outdoors, is an annual. Grown indoors it produces for two days longer than forever. Just make sure to clip any blossom growth, because when it flowers two things happen: leaf growth is curtailed, and the leaves can turn bitter, as the plant puts all its energy into producing seeds. |
