|Planted 3 gardenias along our front fence line. All 3 have grown beautifully and produced abundant flowers. Recently, the rightmost plant has yellow leaves from the base up. There are a few at the base of the middle plant now. What would be causing that?

|Gardenias like moist soil but if it's too wet, it can cause the leaves to yellow and if it remains too wet it can cause root rot. About the only other cause might be a need for iron, especially if the leaves are yellow but the veins in the leaves are a bright green. Wish I could be more helpful but it's difficult to diagnose a problem without being able to see it!
