Soil changing bloom color

Question

Last year my hibiscus were yellow – this year they seem to have changed to a red pink color. I assume that this is probably due to a change in the soil, but not sure what could have changed to make the color different. Any ideas? I liked the yellow better!

Answer 1

Color change in hibiscus is a complicated and interesting phenomenon. This article has a great explanation:

As the article explains, the colors are more likely to be influenced by the weather than the soil, and there's unfortuately no consistent way for us to control which ones show up. The yellow will probably be back, but it's hard to predict when!
