The tiny flowers are completely enclosed in the developing fruits which are borne in the leaf axils and are produced each year. You may find that as a bonsai, however, fruiting is not very common. Figs prefer full sun to part-shade and humus-rich, moist, but well drained soil and shelter from cold winds.

Most rainforest figs produce aerial roots from the branches and trunk. Whether to leave these on or not and incorporate them into the design is a controversial issue for bonsai enthusiasts, although it does matter on the overall design of the tree. The roots are brittle at first, but strengthen and turn into a very strong part of the tree once they reach nutrients.

Other Comments : As bonsai the leaves vary in size on mature trees from 10-12mm (1/2in) up to 90-100mm (3-4in) - depending on the species.

While ficus are voracious feeders, they are very forgiving and can go a couple of days without watering, so water them sparingly to make sure you do not cause the root system to rot.

To reduce the leaf size, defoliating, especially towards the end of summer, is the way to go. You must be sure to remove the growing tip or sheath when you do this however. Prune throughout the whole year by cutting back to about two or three leaves. Thin out larger leaves. It is possible to defoliate in spring.

Propagate from seed or cuttings, or by aerial layering.

General Care : For people living in other-than-tropical climates, the tree should be kept indoors during the winter under fluorescent lights.

Tolerates low light - but likes light. Protect from frost and draughts. Keep inside from minimum 15°C (59°F) to 22°C (71°F).

Place close to a window letting in plenty of light. This plant does not like sudden changes in temperature, nor the sort of draughts which can arise inside living quarters.

Watering must be plentiful during the spring and summer period while the plant is outside. In winter, allow the soil to dry out before watering. Spray the plant often to maintain humidity.
