In general, good fortune only blooms in winter and spring. If the flower period is over, the color in the middle of the flower will gradually become lighter and lighter, and then it will gradually wither, which is a normal phenomenon.
If it's for this reason, we can cut off the flower center in the plant, and start to maintain some side buds near the old seedling. When the side buds grow to about a bunch, we can break them off by hand and put them into the flowerpot again. After that, when watering, you should pour water into the leaf center until the water in the leaf center is full.
Another possibility is that there is a problem in lighting, ventilation or watering. We need to know that pineapple plants like a humid and warm environment. The recommended temperature is between 21 and 28 degrees in the daytime and 15 to 21 degrees in the evening. The maximum temperature can not exceed 35 degrees. If it's because of the light, it's OK to put it under the full light in winter. Other time can be put in the environment with more bright and sufficient astigmatism
