Apply lime to bring pH between 5.0 and 6.5 and add chelated iron. This will often bring good results in chlorotic plants. Heavy metals found in many of these nutrients can last indefinitely in soils and contaminate wells. Apply small amounts to root areas and watch for slow results in the plant before applying more.

For example, a 12-6-4 fertilizer contains 12% nitrogen (N), 6% phosphorus (P), and 4% potassium (K). It's important to note that this does NOT mean that there are only these three elements present in the fertilizer; there may be other trace elements or additives present as well.
