Second, cultivation skills

Be sure to sterilize and kill insects before planting. Change the basin and change the soil every spring. Placed in an environment of 18-25 ℃. Spring, autumn and winter should be exposed to more sunlight, while summer should be shaded or put indoors for good ventilation. During the growing period, nitrogen, phosphorus and potassium compound fertilizer or dilute organic liquid fertilizer was applied every half a month. Variegated varieties should not use fertilizers with high nitrogen content. During cultivation, the striped color of the leaves becomes lighter. This is often caused by excessive shading or excessive application of nitrogen fertilizer. The growing season can be fully watered, and if the basin soil is too dry, the growth is poor, especially in the summer when the vigorous growth is more indispensable. The water quality should be clean to prevent the tree trunk from rotting. But it can not make the soil moisture too high for a long time. Watering and fertilizing should not be applied into the foliage.

Family potted plants should be dry and wet, and the amount of water should be reduced appropriately when the temperature is low. In the dry season, you should often spray water on the leaf surface to keep it moist to prevent the leaf tip from drying up and curling. Indoor maintenance should pay attention to ventilation and often sprinkle water to the surrounding environment to humidify, the humidity is too small leaves easy to lose luster, gray and lifeless. If the indoor scattered light is less, it should be moved to the place with sufficient light every 7-10 days and then transferred after 3-4 days. Variegated leaf varieties should pay more attention to sufficient light and avoid excessive proportion of nitrogen fertilizer when fertilizing, otherwise the variegated leaves are easy to fade.

In order to keep the leaves upright and energetic, 0.1% 0.5% solution of potassium dihydrogen phosphate can be sprayed on the leaves during the growing season. Control watering after the beginning of autumn. Keep the room sunny in winter and keep the temperature at 5-10 ℃.
