I have quite a few anthuriums. They are different colors. It may just be my imagination but it seems that a lot of them are blooming white. I do have some pink ones that are blooming pink, but puzzled about all the ones that are white. I do know that I had some red ones that are not blooming red now. Any ideas or suggestions would be greatly appreciated!
High temperatures can cause the bloom color to fade or wash out. Although it doesn’t occur often, if the pH is high, bloom color can become lighter too. Anthuriums perform best in soil with a pH around 5.5. For additional possibilities, this article may help: https://www.gardeningknowhow.com/plant-problems/environmental/fixing-color-faded-flowers.htm
