Green leaf Jasper likes a warm and humid semi-shady environment. The suitable temperature for growth is about 25 ℃, and the lowest is not less than 10 ℃. It is not resistant to high temperature, requires high air humidity, avoid direct sunlight, and likes moist soil with loose, fertile and good drainage. Potted plants to keep the potted soil moist without stagnant water, watering less rather than more, the principle is dry and then watered. There is bright scattered light in the room, especially in summer to avoid direct sunlight, lack of light will make the leaves lighter and lose their luster.

During the growing period, topdressing should be applied once a month, and watering should be controlled in winter with the water that has been released into the pool for 2 days. The change of temperature directly affects the color of leaves, the optimum temperature in winter is 18-20 ℃ for colored leaves and about 15 ℃ for green leaves. If you are afraid of heat in hot summer, you can spray water under the shade to cool down, but it should be noted that overheating and humidity will cause stems and leaves to blacken and rot. Place plenty of light in winter and avoid direct sunlight in summer. Change the basin every 2-3 years.
