Why Hibiscus leaves turning yellow and falling off
I have 2 Hibiscus plants on my porch. The leaves are turning yellow and falling off. The new ones that grow out remain small. I am careful about overwatering. In the past I have kept other Hibiscus plants in the same location and they have always thrived there. I have checked the leaves for and bugs and have not found any. The surrounding plants are healthy.
