The "secret" to how to grow basil is to give it full sun and moist, but well-drained soil. Growing basil in the winter can be challenging because of its preference for hot, humid, sunny days. It is much easier to meet its needs in the summer.
Sweet basil plant is a tender annual. The species is a vigorous, fast-growing herb. Its oval, bright-green leaves are 1-2 inches long with deeply indented veins.
Tall spikes of small, white flowers appear at the stem tips in late summer. Pinch them off as soon as you see them to prolong the plant's life and to preserve its flavor.
More than 150 varieties are available, but the basics for how to grow basil are the same for all. Sweet basil plant, shown here, is the most widely grown for use in fresh tomato sauces and in pesto. Purple basil makes wonderful flavored vinegar. Many scented basil plants, such as cinnamon, lemon and licorice are used in fruit salads and for garnish.
Pinch growing tips to encourage branching. If you eat basil regularly, you're automatically doing a big part of basil maintenance -- pruning. You'll keep your herb well-groomed and producing tasty, tender new leaves.
Harvest leaves from mature plants every week. Don't worry about wasting a bountiful supply -- freezing basil is a great way of preserving basil for cooking. Gently wash leaves, then pat dry.
Chop fresh leaves by hand or in the food processor. By chopping them finely, they'll be the right size for adding to soups, sauces or other recipes. Store them in freezer bags.
Drying basil is a convenient way for storing it. Don't know how to dry basil? It's easy. Cut off stems and tie in 1 inch bunches with string, leaving a loop for hanging. Hang them upside down and allow them to dry naturally in a cool, dry, dark place.
Origin: India, southern Asia
Height: 1-2 ft (30-60 cm)
Light: Full sun. At least 6 hours of direct sun per day. Turn plant for even growth because it will tend to grow toward the light source. Want to know how to grow basil with an indoor grow light? Just keep the light 6 in (15 cm) above the plant and leave it on for 14 hours a day. This is the equivalent of 6 hours of sun.
Water: Water thoroughly then allow top 1 in (2.5 cm) of the soil to dry out between waterings.
Humidity: Moderate room humidity. Mist the leaves with room-temperature water or put the plant on a tray of wet pebbles.
Temperature: Average room temperatures 60-75°F/16-24°C.
Soil: Well-drained potting mix, such as cactus mix. Or, use 2 parts all-purpose potting mix with 1 part sharp sand or perlite.
Fertilizer: Feed every 2 weeks with a high-nitrogen liquid fertilizer diluted by half.
Propagation: Seed. Basil seeds can be collected from the flowers in autumn. These tiny, black seeds are nestled in the flowers. Shake them loose and save them to plant in spring.
