I have a yellow blooming hibiscus and had it located on the front porch of my home. At first it continued to bloom then started drooping, so we watered it. That seemed to help temporarily, then the leaves began to turn yellow. I have always thought that when leaves turn yellow it is over watering. Even though the leaves are turning yellow, it appears to still need water with droopier leaves. I have since brought the plant indoors, thinking it was too hot outside. I live in Texas, so it gets quite warm outside. Please help, this is the second braided hibiscus I have had and don't want to kill another one.
