Gardenia leaves turning yellow

Earlier this spring I planted three large gardenia bushes and recently noticed the leaves turning yellow on one of them. I asked someone at Pike nursery and they said the soil lacked a nutrient but not to do anything and they would be ok. Now the other two are doing the same thing. Is there something else I should do?

    Yellowing leaves on plants are generally caused by water--likely too much of it--or a nutritional deficiency. It sounds like Pike's is suggesting it is the latter. Take a close look at the leaves on your gardenias. If the yellowing seems to be between the veins on the leaves, that is a sign of chlorosis, and you should apply Ironite or another fertilizer with iron chelate.
