Basil is native to tropical regions of Central Africa and Southeast Asia. It has been cultivated for thousands of years and is a staple herb in many global cuisines, particularly in Italian and Southeast Asian cooking.
Prune basil regularly to encourage bushier growth and prevent the plant from flowering too early (which can reduce leaf production). Pinch off the top few inches of the plant, including the growing tips, to promote branching. Remove any flower spikes as they appear to extend the plant’s productive life.
Harvest basil leaves by cutting them just above a pair of leaves on the stem, which encourages the plant to branch out and produce more leaves. It's best to harvest basil in the morning when the essential oils are most concentrated for the best flavor.
General Prevention: To prevent pest problems, maintain good garden hygiene, avoid overcrowding plants, and water at the base of the plant to keep the leaves dry. Mulching around the plants can help retain soil moisture and reduce weed competition.
