Plants only need a small amount of iron, but the iron is crucial. Iron is needed to produce clorophyll which gives the plant its green colour and aids in photosynthesis. If the plant is lacking iron then the leaves will go yellow – showing the deficiency.

Iron (Fe) is a vital micro-nutrient required by plants in order to form chlorophyll. And chlorophyll is what gives plants/lawn their green colour. Iron deficiency (chlorosis) occurs when there is either not enough iron in the soil, or the iron is tied up and unavailable due to high pH (alkaline soil), or poor aeration. It can also be induced by an over-abundance of calcium in the soil or an over-application of lime.

Iron chlorosis is the name of the condition found in plants that are iron deficient. It is one of the most common micro-nutrient problems of ornamentals, shrubs, vines, small fruits, and trees. Appearing first on the young/new leaves, Leaves of affected plants are yellow, light green, or white with distinct green veins.
