Answer: Although hibiscus are evergreen plants, they do lose some of their oldest leaves at this time of year. The yellowing leaves are usually replaced right away with healthy new growth. So if just the inner and oldest leaves are yellowing, it is normal and natural. If the newer leaves are yellowing, it can indicate over watering or even transplant stress. Water your plant thoroughly and then allow the top of the soil to dry out before watering again. This should improve things. Best wishes with your hibiscus.
