Other ingredients are also essential for […]

Chlorotic (a yellowing of the leaves) azaleas and rhododendron are a common sight in the Indiana landscape. The term chlorosis gets its name from the lack of chlorophyll, the pigment responsible for healthy plants’ green color. One major cause of chlorosis is a deficiency of either iron or manganese. Other landscape plants such as pin oak, river birch, holly and sweet gum are also susceptible to chlorosis. Iron deficiency leads to a pattern of yellowing […]
