Watering and soil

This type of plants should be watered regularly in the hot period, taking care to keep the soil moist, but not soaked. In the winter season, watering must be reduced. M. Leuconeura loves humid places, so it is good to spray water on the leaves, in order to guarantee the correct degree of humidity.

The ideal soil for its cultivation is rich and fertile, with a good degree of drainage, consisting of loam, peat and sand.

This plant has a rapid growth, so it is good to plan to repot it at least every two years when you have young specimens. In the case of adult plants, the plant may no longer require repotting, but it is good to intervene to eliminate a layer of old soil, to be replaced with other rich and fertile soil.


Multiplication

The multiplication takes place by division of the plants or by cutting in the summer, leaving 3-4 leaves per branch. The cuttings should be placed in a mixture of peat and sand and in a constant temperature environment, around 25 ° C.

Some varieties of Maranta are used for food purposes: in particular, a type of edible starch is obtained from the roots.

The name Maranta derives from the scholar Bartolomeo Maranti, who first studied it in the 16th century.

Maranta - Maranta leuconeura: Parasites and diseases

These plants can present problems caused by parasites which, if not countered in time, can cause serious problems. The most common parasites are aphids, spider mites and lice and mealybugs.
