It is a shrub or small evergreen tree, native to central-southern Asia; in nature the adult specimens remain close to 2 m in height. They have thin and ramified branches in a disorderly way, woody or semi-woody, with light brown bark, smooth; the leaves are light green, slightly gray or yellowish on the lower side, they have a rounded shape, a spoon, and a short petiole, they are thick and leathery, opaque. In spring and autumn it produces small fruits, of 1-2 cm of diameter, similar to small figs, of green color, which remain on the plant for months, becoming first yellow, then red, before falling, they contain numerous small seeds, of usually not fertile in the specimens grown far from the place of origin. The ficus deltoidea is much less widespread as an ornamental plant than other species of ficus, it still has a very decorative and particular appearance and is easy to cultivate; in nature it often develops as an epiphytic plant, growing on the trunk of large trees. The sap of the ficus deltoidea is used to produce gum.
For a healthy and luxuriant growth, place the plants of this variety in semi-shaded positions, with abundant brightness. In summer, place in shady places, away from direct sunlight; choose well-ventilated locations, but away from windows or doors, so that the plant does not suffer abrupt temperature changes, which may not benefit the balanced development of the plant. If the plant is placed in a place with little brightness, the promo symptom is given by the fall of the leaves. Take action in a timely manner to prevent the phenomenon from worsening, marrying the plant in a suitable place.
Water regularly, but without exceeding, letting the soil dry well between one watering and another; in summer water more often, especially in very hot periods; in winter water sporadically, without forgetting to vaporize the leaves with distilled water, to increase the environmental humidity, and to avoid that the air is excessively dried by domestic heating. From March to October, provide fertilizer rich in nitrogen every 15-20 days, mixed with the water used for watering.
For the planting of the plants belonging to this variety, use a soft, loose, very rich soil, mixed with pumice stone or perlite, to increase drainage; to obtain a well-developed plant it is good to repot the ficus deltoidea every two years, in autumn so as to allow the roots to have sufficient space.
The multiplication of these plants occurs by cuttings, using semi-woody portions of the apex of the branches, which must be immersed in the rooting hormone and then buried in a mixture of sand and peat in equal parts, which must be kept moist until rooting has occurred; the new plants are therefore placed in a single container.
Ficus deltoidea: Pests and diseases
Pay attention to cochineal and aphids, which often nest on the underside of the leaves. To eliminate the problem it is good to proceed with greater vaporization of the leaves, since the water is an element not liked by these parasites. It is also possible to clean the leaves directly with soap and water, then rinsing carefully. Otherwise, special insecticide products are available on the market that can be useful if the presence of parasites is massive.
