1、 How to trim

When it is found that the leaves of green pineapple turn yellow, they should be trimmed in time, but they cannot be cut off directly. Cut them from the middle of the petiole. This method can avoid water loss. After cutting off, it will grow new leaves. If the leaves turn yellow due to rotten roots, cut off the rotten roots while cutting off the yellow leaves

2、 How to prevent yellow leaves

1. Light: Although lvluo prefers sunshine, it cannot be directly exposed to strong light. Strong sunlight will burn the leaves. Usually, it's best to put it in a place with light in the house. If it's cultured outdoors, it should be shaded at noon when there is a hot sun

2. Moisture: the amount of water should be controlled to keep the soil moist and its leaves will not turn yellow when there is no excess moisture. In summer, we need to spray more water on it and wash its leaves with clean water, which is conducive to plant photosynthesis. It should be watered less when it is dormant in winter. Once there is ponding, the root system is easy to rot and the leaves will gradually turn yellow

3. Temperature: it's best to control the temperature at 20-28 ℃ at ordinary times. If the temperature is lower than 5 ℃ in winter, it will lose its leaves. When the temperature is relatively high in summer, the cooling work should be done well, and windows should be opened properly for ventilation. Yellow leaves are easy to appear in the high-temperature and muggy environment
