The Fig (Ficus Carica), although a native of the Mediterranean region and south-western Asia, is fairly hardy in most parts of England and Ireland, and quite hardy in the mildest parts. As a market or commercial crop it does not figure largely. It is, however, grown in almost every large garden of repute, either on walls with a southern aspect or in pots in greenhouses. It has large deeply lobed leaves, and is remarkable for its thick milky juice and the pear-shaped "fruits " which are borne on the young branches.

The fruits are interesting from a structural point of view. If turned inside out they would resemble the Strawberry "fruit" somewhat in character. What is eaten as the fruit is really the fleshy receptacle on the inner surface of which the flowers are borne. In one form of the Fig, known as "Ficus", female flowers only are borne; in another form, called " Caprificus ", male flowers are borne near the opening, and what are known as " gall" flowers lower down. The gall flowers do not produce seeds, but are used by a small wasp (Blastophaga grossorum) in which to deposit its eggs. The larvae from these occupy the ovary and form a gall. In crawling in and out of the flowers these little wasps carry the pollen from the male to the female flowers, and thus ensure fertilization. The illustration (fig. 377), from Kerner and Oliver's Natural History of Plants, shows the fruits, with male and female flowers, and the insects which visit them. The visits of the insects from one kind of flower to the other result in the process known as " caprification ". It is thought that this is essential to secure the best fruits. In the British Islands, however, excellent Figs are produced without the caprification process.

Open-Air Culture

Fig trees flourish in warm, sheltered, and sunny spots in any good garden soil that has been deeply dug or trenched and well manured. The best time to plant is about March or April, in mild weather and when the soil is friable and easily worked. Autumn planting is not to be recommended, as the plants are likely to suffer in the event of severe frosts overtaking them. The soil should be made firm about the roots, and to prevent grossness of growth a slight dressing of basic slag (2 oz. to the square yard) or some lime should be sprinkled over the border early in spring - more particularly if an annual top-dressing of well-rotted manure is given the preceding autumn. The fruits appear on the young shoots, and those that are first to ripen are already to be seen on the plants in autumn and winter when the leaves have fallen. In the sketch (fig. 378) the large fruits shown at a are not likely to pass safely through the winter in the open air; while the smaller ones, shown at b, will. Beneath the smaller fruits there is a bud from which a new shoot will develop in spring. As the large fruits that are on the shoots in early winter never have a chance of ripening outside, they should be removed. This will induce the trees to throw out a better supply of fruiting shoots in spring.
