It is a genus that includes some species of small evergreen, semi-climbing shrubs, originating from Central and South America. The rigid semi-woody stems, which develop up to 150-200 cm, bear large, heart-shaped, pointed, shiny and waxy leaves; the leaves of syngonium podophyllum are light green, mottled or variegated with white, yellow, dark green; there are numerous hybrids, even with pink or orange leaves. Container grown Singonium plants generally do not produce flowers. Widely used as houseplants, i syngonium podophyllum are often grown in hanging baskets or by twisting the longer stems on special stakes, in order to leave the plants the right space to develop at their best.
The Singonio specimens are grown in a very bright position, but sheltered from direct sunlight; in spring and summer it is possible to place the plants outdoors, in a shady place, during the cold months, however, they shelter at home, as they prefer minimum temperatures above 10-15 ° C. The ideal temperature for the cultivation of Singonio is around 20 ° C. It is a plant that likes a good air exchange but cannot stand cold drafts, so it should be placed in a sheltered place.
As for the water supply, it is essential to water regularly, avoiding water stagnation which are harmful, but keeping the soil constantly moist. During the winter the waterings must be reduced, taking care however to check that the soil does not dry out excessively. When the temperatures are very high it is good to intervene by nebulizing water at room temperature on the foliage.
From March to October, mix fertilizer for green plants with the watering water every 15-20 days. Syngonium podophyllum do not tolerate drought, some varieties are in fact used as vegetation for aquariums.
To plant the singonio specimens use a soft, light and balanced soil, which is possibly able to slightly retain humidity. These plants develop quite quickly, it is therefore advisable to repot them even annually if you notice that the pot is small for the size of the root system. Repotting should be done in early spring.
The reproduction of specimens of this genus occurs by stem cuttings, preferably in spring. It often happens that the stems root spontaneously by touching the ground, or that they produce aerial roots. The cuttings must be placed in a mixture of peat and sand and kept in a sheltered place with a temperature around 20 ° C until they take root.
Singonio - Syngonium podophyllum: Parasites and diseases
This plant fears root rot and cochineal; the presence of this parasite is immediately evident because what looks like cotton flakes form on the leaf surface. It is possible to eliminate them manually with a cloth and alcohol if they are limited, otherwise it is good to resort to the use of a special insecticide product.
In some cases it can also be affected by aphids that can be eliminated by increasing the amount of humidity, a factor that allows the removal of the parasites.
