2. Watering: Ivy likes to be wet, so it is necessary to keep the soil in a wet state at all times. Water can be sprayed on the leaves or around in spring and summer to increase the air humidity. The amount of watering should be reduced in autumn and winter, and it is best to keep the soil dry in winter.
3, lighting: the cultivated ivy must have sufficient light. If it is cultivated indoors, it is best to put it in the south window position, which can better receive sunlight, so that it can grow faster and the leaf color will be more vivid, but it cannot be exposed to strong light.
4. Temperature: The suitable temperature for its growth is 18-20℃, and its cold tolerance is very good, even if it is 0-5℃, it will not be harmed. Generally, 10℃ is the best. If the temperature is higher than 35℃, it will stop growing and its leaves will turn yellow.
Second, the propagation method 1, cutting propagation: cutting can be carried out in an environment with a suitable temperature. Cut the stems and vines about 10 cm, insert them into the soil 1/3, then water them, cover them with a film and put them in a cool place. After rooting, plant them in pots and water them.
2, layering propagation: smooth it and cover it with some wet sand. Soon, you can observe the emergence of new roots, and then cut them off one by one, and you can plant them into plants.
3. Common pests and diseases 1, leaf spot disease: it will cause the leaves to dry up or even fall off. When the diseased leaves are found, they should be removed and burned in time to avoid increasing the source of infection. Ventilation and light transmission should be strengthened, and 800 times of 40% wettable powder should be sprayed at the same time.
2, scale insects: will cause the leaves to yellow or dry, if the area is small, it can be manually clear, if the area is large, it can be sprayed with chemicals.
