QUESTION: Wilmington, DE
Many of my rhododendrons' leaves are turning slightly then increasingly yellowish. Is there a specific fertilizer that's useful in preventing that?

ANSWER: It is natural for your rhodo to have some leaves yellow and drop. Even evergreens will shed leaves. If the leaf drop is severe, check the underside of the leaves for insects. In addition, rhododendrons need good drainage with plenty of moisture, but their roots will rot if the soil stays too wet, which can cause the whole shrub to turn yellow. Rhododendrons do need acid soil, so use an acid fertilizer formulated for them if your soil is on the alkaline side. Feed them after they bloom in the spring.
