Cultivation techniques:

Water and fertilizer management: During the growing period, compound fertilizer can be applied 3-5 times as a top dressing, but the amount of nitrogen fertilizer should be controlled to avoid excessive vegetative growth affecting reproductive growth and reducing flowering. During maintenance, watering should be properly controlled to form a well-developed root system.

Temperature management: The optimum growth temperature is 20-30°C. At 10°C it enters a semi-dormant state, and below 5°C it will be frostbitten, so in winter attention should be paid to warmth and shelter from wind.

Light management: It likes a warm, humid and sunny environment, and can also be placed in a slightly shaded place, but insufficient light reduces flowering.
