Growing herbs in your house is easy. You do need a window that faces east or south so your herbs will get the six to eight hours of sunlight they require in order to thrive. Their care and upkeep, however, is not difficult or time-consuming, and a number of herbs do well inside, including anise, basil, caraway, chives, cilantro, cumin, dill, lavender, mint, oregano, rosemary, sage, thyme and winter savory.
Wash your pots in hot, soapy water and rinse well. Plant your young plants or seeds according to the directions on the package. Use a commercial potting soil, or mix equal parts of potting soil with perlite, peat moss and sand. Water well and place the plants in a sunny window.
Fertilize your herbs about every two weeks. Don't fertilize any more frequently than that, or you can impair the herbs' taste and aroma. Water when the potting mix starts to get dry; test with your finger, because looks can be deceiving. People are more apt to overwater plants than underwater, so be careful. Turn the pots about every four days so the plants will get even amounts of sun on all sides.
Keep the heat in the house at 70 degrees or lower. If your house is dry, help the herbs retain their humidity by grouping them together. You can also put rocks on a tray, put the herbs on the tray and pour water on the bottom of the tray up to the bottom of the pots to create a more humid environment.
Use your herbs regularly to keep the plants growing. When you cut off a sprig, you encourage new growth. Use herbs in cooking, for beauty treatments and in home remedies for illness, such as mint tea for a stomach ache.
