I planted a few Turner's flirt oleanders a few weeks ago and notice that their leaves are going yellow. Can you tell me why this might be and what I can do? Thanks, Marigold

This time of year it is normal for some of the oldest leaves to turn yellow and fall off. New leaves will take their places. However, if all the leaves are turning yellow it indicates a water stress problem - either too much or too little. Oleander can be watered deeply once a week and it should be happy. Water as usual and then check the soil moisture by digging down. If the soil is still moist one inch beneath the surface you won't need to water for a few more days; if it's dry, it's time to water. Hope this information helps!
