It belongs to the plant with short sunshine. When it is cultivated in normal times, it is exposed to bright light and can not grow in the place without light for a long time. When it is cultivated in normal times, it should also avoid the hot sun. It is most suitable to cover 60% - 70% of the sun, and suitable light can promote growth.
Soil is the basis of growth. It is better to provide loose and well drained sandy soil. The size of pH value will affect the color of flowers. When the pH value is small, the color of flowers will be dark blue. When the pH value is slightly large, the color of flowers will be pink.
The most suitable temperature for growth is 18-28 ℃. Keep warm in winter. The temperature should not be lower than 5 ℃. When the temperature is kept above 20 ℃, the flowering will be promoted, and when the flower is open, it will be kept at 16 ℃, which can prolong the flowering period.
Basin soil must be kept moist, and sufficient water must be kept in the growing season, so as to ensure good growth. In rainy season, because it is very humid, it is necessary to discharge water in time to prevent root rot due to water logging. Keep it a little dry in winter. If it is too wet, the leaves will rot.
It likes fertilizer. In the growth stage, it needs to apply fertilizer and water for pancakes every 15 days. Before flowering and in the bud stage, it can spray leaf fertilizer properly.
