How Long Does Basil Last?

Description

• Basil is an herb characterized by a light licorice, clove or spicy flavor and fresh grassy smell. It is an herb commonly used by many nationalities -- and there are more than 50 species recorded. There are sweet, lemon, purple-leaved and cinnamon basil, among others. Basil is usually a large-leaved plant, which is also used for its oil. Generally, basil is an herbaceous compact herb, but may grow up to 2 feet tall and become slightly woody. When young, all parts of the herb are edible, but the leaves are considered the most flavorful.

Time Line for Plants

• Basil will become woody as it gets older, and the production of nice big leaves will slow towards the end of its life. The plant will also flower much more, and pinched ends will yield smaller growth but thicker stems. Most basil is annual and will succumb in the home garden unless brought indoors to a sunny, warm location. Even then, it will slowly begin to die back until there are no new leaves. Without leaves, the plant cannot perform photosynthesis and it will die.

Cultivation

• Basil starts easily from seed which should be sown indoors four to six weeks before the last frost. When all threat of cold weather is passed, plant the seedlings in a full-sun location in the garden. Ideal temperatures for basil are at least 75 degrees F. Pinch or prune back basil every month for the best leafing and compact growth. Pinch off flowers as they occur or the plant will go to seed. In warm climates, the plants can be grown from about April or May into the late fall. In temperate climates, the growing season is limited to the period of late spring or early summer until late summer.

Preserving Basil

• Pesto, the classic garlic herb sauce, is an excellent way to preserve basis. It freezes well and can last in the refrigerator for several weeks. Freshly cut basil should be treated as cut flowers. Place the stems in just enough water to cover them and change the water daily. Basil leaves will blacken if stored for too long in the refrigerator, but will last up to two weeks on the counter in water. Basil leaves can also be layered and frozen or pureed and put in ice cube trays.
