1、 Normal curing
1. Specific reasons: if it is a newly bought green pineapple or just inserted into a bottle for water cultivation, it will generally have an adaptation stage, about a month. During this stage, if the leaves turn yellow, this is normal p>
2. Solution: do not directly remove these yellow leaves, but cut the middle part of their petioles with scissors. We should also pay attention to ensuring that the surrounding environment is appropriate and make it adapt slowly p>
2、 Provide a warm environment
1. Specific reasons: if it is in winter, it may be that the leaves turn yellow due to freezing injury, because it is more sensitive to temperature p>
2. Solution: special attention must be paid to the temperature during overwintering. Safety can only be guaranteed if it is not lower than 10 degrees p>
3、 Provide appropriate scattered light
1. Specific reasons: Green pineapple itself likes light, and the formation of chlorophyll also needs light. If the light condition is not good and the environment is too dark, the leaves may turn yellow in a large area p>
2. Solution: provide appropriate scattered light, but the light should not be too strong. The illumination time in winter can be extended appropriately p>
