The Q&A Archives: Reasons for Yellowing Leaves on Gardenias

Question: We recently planted some dwarf gardenias that seem to be putting on new growth and are now budding for flowers, but the larger closer-in leaves are turning yellow. The plants are getting plenty of sun (south and west exposure) and plenty of water. Infact, we think we may be watering too much. Could this be the cause of our yellow leaves? Thanks for your help.

Answer: It sounds like you're doing everything fine to your gardenias. The older leaves usually are the first to show stress symptoms and yellow. It may be too much water (especially if the soil is heavy and poorly drained) or poor fertility. Try fertilizing with a food recommeded for gardenias (acid food with iron). Check the fertilizer package to be sure gardenias are one of the plants mentioned. Cut back on watering if it's wet and mulch the base of the plant with pine straw to help conserve moisture when it does dry out.
