The suitable growth temperature is 20 ℃ - 30 ℃, the best growth temperature is 18 ℃ - 21 ℃ in the daytime, 16 ℃ - 18 ℃ in the night, and it can survive the winter safely above 10 ℃.
Therefore, in summer, it is necessary to prevent high temperature exposure, and put the double line taro in a cool place, pay attention to cold prevention in winter, and transfer the plant indoors.
The growth period of arrowroot is vigorous from 3 to October. The air humidity should be kept at 75%-85%. High air humidity is conducive to the expansion of leaves. Therefore, it should be watered more frequently during the growth period and spray to the foliage.
The suitable watering method is to spray the leaves in the morning, water the basin in the afternoon, and irrigate the whole plant in the evening.
Double line taro is not resistant to direct sunlight, so shade should be done in summer. Let the two line taro absorb the scattered light.
It likes fertile and loose soil, but does not like soil hardening and ponding.
Generally, fertile humus soil and porous coarse medium are used as matrix.
The principle of "a small amount and many times" should be followed in the fertilizer application of double line bamboo taro. In the peak growing season, peanut bran and compound fertilizer or compost should be applied every two weeks.
Plants need a lot of water in summer, so they should be watered 3-4 times a day.
In autumn and winter, the temperature decreases, and the growth speed of the double line taro slows down. Therefore, the amount of water should be reduced, which can be once a day or 2-3 days a day, so as to keep the soil dry as much as possible.
In summer, the sun is strong, and the leaves of the double line taro are easy to be burned under the direct sunlight, so the plant should be placed in the place without direct sunlight. If the leaves are found to be burned, the leaves should be cut off immediately to avoid the invasion of pathogenic bacteria.
Fertilization was stopped in dormancy period in winter and hot period in summer.
The concentration of fertilization should not be too high, otherwise it will cause leaf burn, and the plant will die in serious cases.
