Fig Tree

Ficus carica

1. Identification and origin

The fig tree (Ficus carica L.), belonging to the Moraceae family, is a tree species native to the Mediterranean region and Southwest Asia, where it has been cultivated for millennia. It is one of the oldest fruit trees domesticated by humans, with archaeological records dating back more than 6,000 years. The species belongs to the genus Ficus, which includes more than 800 tropical and subtropical species, but F. carica stands out as the only one widely cultivated in temperate climates. Its adaptation to dry environments and poor soils favoured its expansion throughout the Mediterranean basin, the Middle East, North Africa and, later, America and Australia.

2. Economic importance

The fig tree is valued for the production of fresh and dried figs, with strong importance in traditional and gourmet markets. Countries such as Turkey, Egypt, Morocco, Iran, Spain and Italy are major producers. The fruit is appreciated for its sweet flavour, nutritional value and culinary versatility. The crop offers good profitability in rainfed systems, being relevant in Mediterranean-climate regions.

3. Botanical characterisation

A deciduous tree of medium size (3–10 m), with a broad canopy and fragile branches. The leaves are large, palmate, deeply lobed and rough in texture. The “fruit” is actually a syconium — a fleshy infructescence containing numerous internal flowers. There are uniferous varieties (one annual harvest) and biferous ones (two harvests: breba figs and main-crop figs). The roots are vigorous and exploit dry soils well.

4. Soil and climate requirements

It adapts well to Mediterranean climates, tolerating hot, dry summers and moderate winters. It withstands light frosts, but very low temperatures can damage young branches. It prefers well-drained soils, of medium to light texture, with a pH between 6.0 and 7.5. It tolerates poor and stony soils but is sensitive to waterlogging. Production benefits from good sun exposure and supplementary irrigation in critical phases.

5. Main pests

• Fruit fly (Ceratitis capitata): internal damage and premature fruit drop.
• Scale insects (Coccoidea): sap sucking and honeydew production.
• Mites (Tetranychus spp.): chlorosis and reduced vigour.
• Fig fly (Silba adipata): perforations and deterioration of the fruits.
• Occasional lepidopterans and coleopterans: foliar damage and perforations.

6. Main diseases

• Anthracnose (Colletotrichum spp.): dark spots on leaves and fruits.
• Root rots (Phytophthora spp.): associated with poorly drained soils.
• Sooty mould (saprophytic fungi): development over scale-insect honeydew.
• Woody cankers (opportunistic fungi): associated with wounds and water stress.
• Occasional viruses: mosaics and leaf deformations.

7. General crop management

This includes choosing varieties adapted to the local climate, planting in well-drained soils, formative and fruiting pruning for canopy aeration, moderate but regular irrigation in dry periods, balanced fertilisation, monitoring of pests and diseases, and harvesting at the ideal ripeness point. The fig tree is suited to rainfed systems but benefits from controlled irrigation to maximise fruit size and quality.
