Most herbs need a warmth in order to grow. Keep them in rooms that are at least 65-75°F during the day, and no less than 55-60°F at night. Even though many herbs can survive at lower temperatures, they are unlikely to produce much growth under those conditions.
Are herbs still good after flowering?
Harvest flowering herbs like basil, sage and thyme before their flowers bloom. Once they bloom, the leaves lose their flavor. I prefer to snip off all the flower buds so that the plant lasts longer. Once the plant flowers it will start to make seeds and stop producing leaves.

Generally, its growth cycle doesn’t include overwintering; rather it dies down and the hard seeds wait in the ground over winter and then germinate during the spring thaw. When temperatures dip, basil suffers cold damage almost immediately in the form of blackened leaves. Therefore, basil and cold weather do not gibe.
Do I cut back thyme in winter?
