The double-line arrowroot likes sufficient scattered light, but is afraid of strong light irradiation, so do not put it in the sun, too much sun will burn its leaves, causing irreversible damage, but bright scattered light is more suitable for its growth.
The most suitable growth temperature of Maranta arundinacea is 20-30 , which is afraid of heat and cold. In summer, when the temperature exceeds 35 , it needs to be shaded and cooled. In winter, the temperature should be kept above 15 to prevent frostbite of leaves.
The double-line arrowroot should not be short of water during the growth period, but the soil should not be in a wet state for a long time, otherwise it is easy to accumulate water, resulting in the rot of the double-line arrowroot root system. Usually, it is necessary to wait for the soil surface to dry before watering. In winter, when the temperature is low, it is necessary to reduce watering and open the watering interval.
The newly bought double-line arrowroot should be kept indoors, and a higher air humidity should be given to it. For example, a humidifier should be placed next to the potted plant, or on the premise of good ventilation, water should be sprayed frequently on the surface of the plant to humidify it, so as to prevent the occurrence of scorched rolls and dry leaves of the double-line arrowroot.
Spring and autumn are the growing seasons of Maranta arundinacea, and the balanced fertilizer water of nitrogen, phosphorus and potassium can be applied once every half month. Before the low temperature in late autumn, the application of nitrogen fertilizer should be stopped, and more phosphorus and potassium fertilizer should be applied, which can improve the freezing resistance of Maranta arundinacea, which is conducive to the safe overwintering of plants, and the fertilization should be stopped after winter.
