temperature
The suitable growth temperature is 20-30℃, the optimum growth temperature is 18-2 1℃ during the day, 16- 18℃ at night, and the safe wintering temperature is 10℃. Therefore, it is necessary to prevent high temperature exposure in summer and put it in a cool place; Attention should be paid to cold protection in winter, and plants can be moved to windless and warmer indoor for wintering.
water requirement
During the growth period of taro, the air humidity should be high and the humidity should be above 80%. Spray it several times in the morning and evening, but the pot soil should not be too wet, otherwise it will easily damage the root system. Lack of water can easily lead to withered leaves and poor growth. Don't water the new leaves too much when they begin to sprout. With the increase of new leaves, the amount of water should be increased gradually, which is beneficial to the healthy growth of plants.
intensity of illumination
The light should not be too strong, and it should be slightly shaded in summer. It is best to be in a semi-cloudy environment with fresh leaves. Avoid exposure to hot sun and dry and hot wind.
Nutrient fertilizer
Fertilize 1 time every half month during the growth period, and add phosphate fertilizer appropriately. In winter, the soil can be slightly dry and the number of fertilization can be reduced.
