What does Iron do for Your Plants

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 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. Leaves of affected plants are yellow, light green, or white with distinct green veins.

Why Add Iron to Plants in Perth

WA coastal sands have high limestone content that blocks the plant being able to take up and use iron. The added sulphur will also help to correct the alkalinity the limestone adds to the soil so balancing the PH. Adding iron based fertilisers in a liquid form in winter will also help lawns to stay green even if the roots have gone dormant.
