It's not hard to grow herbs inside during the winter, as long as you have a sunny window you can place them by. They need six to eight hours of sunlight every day, along with water and just a little bit of attention. Many herbs thrive inside, including rosemary, thyme, sage, basil, caraway, chives, cilantro, cumin, winter savory, lavender and dill.
Choose which herbs you want to grow. Consider what types of herbs you currently use and what types you would like to experiment with. Don't limit yourself to herbs you can use in recipes, because there are other uses for herbs. Lavender and rosemary, for example, are used in home spa treatments.
Wash your pots in hot, soapy water and rinse well. Fill the pots with potting soil or a mixture of equal parts potting soil, perlite, peat moss and sand. Read the seed packets for directions on how deep to plant the seeds, as this will vary from one herb to another. Water them thoroughly. Put the plants in a sunny window.
Water regularly but only when the soil is dry. Fertilize about every two weeks. With herbs, it's better to underfertilize than overfertilize. Turn the plants every few days so each side gets some sun. The temperature of your house should be kept at 70 degrees or lower. Run a humidifier and group the herbs together to help them retain moisture. Also, put rocks on a tray with your herbs and dribble some water on the tray, just to the bottom of the pots, to keep the humidity up.
Cut a sprig of each herb regularly to encourage new growth.
