Tiger eye Rohdea japonica likes sunshine and is afraid of strong light. In the late autumn, winter and early spring, because the temperature is not very high, it should be given direct sunlight to facilitate its photosynthesis, flower bud formation, flowering and fruiting. In case of high temperature or in summer, it needs to be covered with about 50% of the sun.
After flowering, those placed indoors for maintenance and appreciation should be placed near the southeast door and window to extend the flowering period and increase the flowering quantity as much as possible.
Tiger eye Rohdea japonica likes cold and dry air environment. It is difficult to spend summer for fear of extreme heat; it is not resistant to frost and cold. When the temperature drops below 10 ℃, it will enter into dormancy. The most suitable growth temperature is 15-28 ℃. Rainy days are too long, susceptible to infection. Keep the leaves dry at night. The optimum relative humidity is 40-65%.
Spring and autumn are the peak seasons for its growth. The management of fertilizer and water should follow the sequence of "light fertilizer" -- "light fertilizer" -- "clear water" -- "light fertilizer" -- "light fertilizer" -- "clear water" (at least twice a week "light fertilizer" should be guaranteed). The interval period is about: 1-4 days for outdoor maintenance, shorter interval period in sunny or high temperature period, longer interval period in rainy or low temperature period or no watering; 2-6 days for indoor maintenance, shorter interval period in sunny or high temperature period, longer interval period in rainy or low temperature period or no watering.
Summer is a slow growing season, so we should control fertilizer and water properly. The management of fertilizer and water shall be carried out in the order of "light fertilizer" - clear water - "light fertilizer" - clear water, with the interval of about 1-4 days for outdoor maintenance, shorter interval between sunny days or high temperature, longer interval between rainy days or low temperature or not; 2-6 days for indoor maintenance, shorter interval between sunny days or high temperature, rainy days or low temperature. Longer intervals or no watering. Irrigate in the morning or evening when the temperature is low, and spray the plants regularly. The watering time should be arranged in the morning when the temperature is low.
Winter is the dormancy period of Rohdea japonica tiger's eye, which is mainly to control fertilizer and water. The fertilizer and water management cycle is based on the sequence of "light fertilizer" - clear water - "light fertilizer" - clear water - clear water, with an interval of about 7-10 days. The interval is shorter in sunny or hot days, longer or no watering in rainy or cold days. The watering time should be arranged in sunny days with high temperature at noon.
The virus is transmitted by aphids, and can be controlled by spraying 2.5% rotenone 800 times liquid.
