Keep in mind some herbs don't germinate as well indoors as they do outside. Seedlings need a few weeks to get established, but then start cutting them back. Even if you want to leave flowers on the plants for the bees, cut most back for bushier, shapelier, plants. Check out books and references about herbs and their uses. Start with a basic reference that gives scientific names and general information.
Some herbs can be harmful if used incorrectly.
Always check with your doctor before trying herbs for medicinal use. Plant for all seasons, and if you're in a colder area, try hardier herbs such as lavender, rosemary, thyme and sage. Make a record of new spring plantings and their care. Paste seed packets and instructions into your journal. Choose plants for texture, leaf and flower color, scent and taste.
