Low temperature in winter, high humidity, less water, strong summer plant growth, high temperatures should be poured; but avoid shower showers in summer, must use the film to prevent rain. Watering is appropriate in the early morning. Autumn rain, prone to black spot. It is better to water at sunny noon in winter.

Slow growth in autumn and winter, should be less fertilized, fertilized once every half-month. Spray a small amount of water after fertilization to prevent the fertilizer from contaminating the leaves.
