Ocimum basilicum, commonly known as sweet basil, is a fragrant annual herb belonging to the mint family. It originates from tropical regions in Central Africa and Southeast Asia but has become widely popular worldwide for its aromatic leaves, which are used in a variety of cuisines, particularly Italian and Southeast Asian dishes. Growing up to 30 to 60 cm tall, sweet basil boasts glossy, oval leaves and small, white flowers that bloom on a terminal spike. Its leaves are the main culinary source, although the flowering tips can also be used for flavoring. Sweet basil is also noted for its medicinal properties, which include digestive and anti-inflammatory benefits.

How to care for Sweet Basil
Water
Water basil plants evenly to keep the soil moist but not soggy. Water at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases. During hot weather, basil may need watering daily, especially if grown in containers. Reduce watering in cooler weather to prevent root rot.
Light
Sweet Basil requires full sun exposure to thrive, ideally receiving at least 6 to 8 hours of direct sunlight per day. In hotter climates, some afternoon shade can prevent wilting and burning of the leaves.
Nutrients
Sweet basil benefits from consistent fertilization, particularly during active growth phases. A balanced, water-soluble fertilizer applied every 4 to 6 weeks is recommended. Ensure not to over-fertilize, as this can lead to less flavorful leaves. A low-nitrogen, high-potassium fertilizer can help promote stronger aromatic qualities in the leaves.
Temperature
Basil thrives in warm conditions and is sensitive to cold. The ideal temperature range for growing basil is between 70°F and 90°F (21°C to 32°C). Protect basil from temperatures that drop below 50°F (10°C) as frost can severely damage the plants.
