It is a genus which includes some species of small evergreen shrubs, semi-climbing, originating in Central and South America. The rigid semi-woody stems, which develop up to 150-200 cm, carry big heart-shaped leaves, pointed, glossy and waxy; the leaves of syngonium podophyllum are of a pale green colour, mottled or variegated of white, yellow, dark green; there are several hybrids, even with pink or orange leaves. Usually, the plants of Singonium cultivated in container do not produce flowers.
Very much used as apartment plants, the syngonium podophyllum are often grown in hanging baskets or by twisting the longer stems on special braces, so as to leave the plants the right space to develop at their best.
The >>Singonio should be grown in a very bright position, but sheltered from direct sunlight; in the spring and summer it is possible to place the plants outside, in a shady place, but during the cold months they should be sheltered in the house, because they prefer minimum temperatures above 10-15°C. The ideal temperature for the cultivation of the Singonio is around 20 °C.
It is a plant which likes a good exchange of air but which does not bear the cold air currents, therefore it is to be placed in a sheltered place.
As far as the water supply is concerned, it is essential to water regularly, avoiding water stagnations that are harmful, but keeping the soil constantly moist. During the winter, watering should be reduced, but make sure that the soil does not dry too much. When the temperatures are very high, it is better to intervene by spraying water at room temperature on the foliage.
From March to October, mix green plant fertiliser with water from watering every 15-20 days. The Syngonium podophyllum does not tolerate drought, some varieties are used as vegetation for aquariums.
To plant the specimens of Singonio use a soft, light and balanced soil, which possibly is able to slightly retain moisture. These plants develop quite quickly, so it is advisable to repot them even annually if you notice that the pot is small for the size of the root system. The repotting should be done in early spring.
The reproduction of the specimens of this genus takes place by stem cutting, preferably in spring. It often happens that the stems root spontaneously touching the ground, or that they produce aerial roots. The cuttings are to be placed in a mixture of peat and sand and kept in a sheltered place with a temperature around the 20 °C until they take root.
Singonium – Syngonium podophyllum: Parasites and diseases
This plant fears root rot and cochineal; the presence of this parasite is immediately evident because on the leaf surface are formed what appear to be cotton flakes. It is possible to remove them manually with a cloth and alcohol if they are limited, otherwise it is advisable to use a special insecticide product.
In some cases it can also be affected by aphids that can be eliminated by increasing the amount of moisture, a factor that allows the removal of parasites.
