Figs should be planted in well drained soils and can grow well in either coarse sandy soils to relatively heavy clay soils. Figs are one of the most problem-free fruits that can be grown in mild winter areas. In sandy soils however, fig trees can suffer extensive damage from root knot nematodes There are four distinct horticultural types of figs, but climatic factors preclude the cultivation of all but the common fig in Texas and other states along the Gulf coast.

    Close Encounters With the Environment Botanical Briefs: The Fig—Ficus carica L. Thomas W. McGovern, MD Clinical Importance Figs can cause irritant reactions with erythema, ulceration, or bullae; phototoxic reactions with bullae and hyperpigmentation sometimes followed by depigmentation and keloids; and chronic eczema with paronychia.1 These dermatoses occur in those who cultivate, gather, pack, or consume figs. The ability of fig plant extracts to stimulate pigmentation in vitiligo patients has been known for almost 2000 years,1 and in India fig extracts are used to treat eczema and psoriasis.2 In addition, the latex has been used as a treatment for warts.3 Family The family Moraceae (the mulberry family) contains 53 genera with about 1400 species, approximately 800 of which are in the genus Ficus. Family members include trees, shrubs, lianes, and herbs that usually have lacticifers with a milky latex.3 Distribution of Plant Ficus carica is probably a native of southwest Asia that rapidly spread to the Mediterranean region, where it was cultivated in Egypt at least 6000 years ago. Today the fig is cultivated mainly in temperate climates throughout the world but also thrives in tropical and subtropical regions. Ficus carica can grow among rocks, in woods, and in hot, dry soils. The first figs in the New World were planted in Figure 1. A young tree of Ficus carica L. about 3-feet Mexico in 1560. In 1669, Europeans sent figs to tall.

  • Figs in Merced County Compared to the 92,000 Acres of Almonds in Merced County, the Modest 2,000 Acres of Figs Seems Insignificant
    Merced County Figs In Merced County Compared to the 92,000 acres of almonds in Merced County, the modest 2,000 acres of figs seems insignificant. But that acreage makes Merced County the second most important fig county in North America – second only to Madera. The mild Mediterranean climate of the San Joaquin Valley and the availability of water during summer make this the perfect area to grow figs. Figs have a history in Merced County reaching back probably 100 years. At one time, one of the unofficial slogans for Merced County was “Home of the Fig”. Most common fig variety in the County is the Calimyrna, which is used for drying and for paste. The best fruits are sold whole and the rest are processed into paste for a variety of products – the most famous of which is the fig “New- ton”. The (black) Mission fig is harvested mostly for dried and paste, but some fruit is hand picked from the tree and marketed fresh – some to far away places. The light green Kadota fruit is dried, shipped fresh and sometimes canned. The only fig cannery in the country is here in Planada – Oasis Foods. Figs are interesting botanically. With very soft wood, morphologically, figs are somewhat similar to grapes. They can be damaged by very cold winter temperatures. The Ka- dota trees are trained very close to the ground and some- times can be confused as very large head-trained grape- vines. The Kadota orchards around Planada are a favorite subject for photographers, especially when the mustard is in bloom.

How, where, and when the domestication of crops plants occurred is slowly becoming revealed although not completely understood (Camp et al. 1957; Smartt and Simmonds 1995; Gepts 2003). In some cases, the genetic distance between wild and domestic plants is so great, maize and crucifers, for example, that their origins are obscure. The origins of the ancient grains (wheat, maize, rice, and sorghum) and pulses (sesame and lentil) domesticated in Neolithic times have been the subject of intense interest and the puzzle is being solved with the new evidence based on molecular biology (Gepts 2003).
