Basil does well under grow lights indoors during the winter. Set the lights to be on 16 hours a day. Take cuttings now, that have at least 6 leaves. Pull off the bottom three and put the cutting in water. In two weeks, the basil roots adequately to plant it in a pot. Set it under the light, close to the light. As the basil grows, raise the light so it doesn’t touch the top leaves. Take cuttings from these potted basils during the winter, and root these in water and plant them also. The basil actually blooms under grow lights.
It’s refreshing to snip fresh basil leaves in January and February and enjoy them in pasta dishes or salads.
