Basil
Ocimum basilicum
Also known as: Sweet basil
Basil is a warm-season annual herb grown for its aromatic leaves, used fresh and dried as a culinary herb and as a source of essential oil for the food and fragrance industries.
Basil is one of the most widely grown culinary herbs, cultivated in field, protected-cropping, and hydroponic systems across a broad range of climates. Numerous cultivars differ in leaf size, color, and aroma profile.
As a warm-season annual with essentially no frost tolerance, basil is typically transplanted or direct-sown after the danger of frost has passed and grown through a single warm season, or year-round under protected cultivation.
Overview
Basil is grown for its leaves, which are used fresh, dried, or processed into oils and extracts. Production spans open-field horticulture, greenhouse and tunnel systems, and soilless hydroponic operations supplying fresh-cut and potted herb markets.
Because leaf quality and aroma are central to its value, harvest timing, handling, and post-harvest cooling are managed carefully to limit wilting and discoloration.
Botanical classification
- Family
- Lamiaceae (mint family)
- Genus
- Ocimum
- Principal species
- Ocimum basilicum
- Growth habit
- Upright, branching annual herb with opposite leaves and terminal flower spikes
Origin and distribution
Basil is believed to have originated in tropical Asia and has been cultivated for millennia across South and Southeast Asia, the Mediterranean, and beyond, becoming a defining herb in numerous regional cuisines.
Today, basil is grown commercially in many countries for fresh, dried, and processed markets, with production and trade data compiled at national and regional levels rather than through a single global dataset.
Climate and soil requirements
Basil requires warm growing conditions and is highly sensitive to chilling injury and frost, which quickly damage or kill foliage. Growth is fastest under warm days and nights with adequate light.
Fertile, well-drained loams and sandy loams support healthy root growth; waterlogged or poorly aerated soils increase the risk of root and stem diseases.
Cultivation and management
- Transplants or direct seeding after risk of frost and chilling has passed
- Adequate plant spacing and airflow to reduce humidity around foliage and limit foliar disease
- Repeated cutting or pinching to encourage branching and extend the harvest period
- Crop rotation and sanitation to manage soil-borne pathogens where basil is grown in the same beds repeatedly
Nutrient considerations
Nitrogen supports leafy growth central to basil’s value as a fresh herb, while potassium contributes to overall plant vigor across repeated harvests.
Water and irrigation
Basil requires consistent moisture for tender, high-quality leaf growth but is sensitive to prolonged leaf wetness, which favors foliar disease. Drip irrigation is widely used in field production to keep foliage dry.
In greenhouse and hydroponic systems, irrigation and nutrient delivery are managed together according to the specific production method used.
Common diseases and pests
Basil downy mildew is one of the most economically significant diseases of the crop worldwide, spreading rapidly under humid conditions and causing characteristic yellowing and leaf drop. Fusarium wilt can also affect basil, causing vascular disease and plant collapse. Aphids, thrips, and spider mites are common pests affecting foliage.
| Problem | Type | Notes |
|---|---|---|
| Downy mildew | Disease | Major foliar disease under humid conditions |
| Fusarium wilt | Disease | Vascular disease causing wilting and collapse |
| Aphids | Pest | Sap-feeding insects on young growth |
| Thrips | Pest | Cause leaf scarring and can spread viruses |
| Spider mites | Pest | Favored by hot, dry conditions |
Harvest
Leaves and shoot tips are harvested by hand or machine before flowering, when aroma and leaf quality are typically highest, with repeated cuttings possible over the growing period as new growth develops.
Uses
- Fresh and dried culinary herb used widely in cooking
- Essential oil extracted for the flavor and fragrance industries
- Potted and fresh-cut herb products for retail markets

How to read figures on this page
Production, area and trade figures for any crop change from season to season and are compiled by FAO and by national agricultural statistics agencies. Take current numbers from those primary sources, dated to the period you mean, rather than from a secondary summary — including this one.
Crop water requirements are estimated from reference evapotranspiration and local climate data, following methods published by FAO and national agricultural agencies. A requirement quoted without the reference method and the local climate behind it is not a number that can be applied to a field.
