Iron is an essential micro-element for plants to synthesise Chlorophyll and make use of nitrates.
Iron deficiency is common in alkaline soils having higher pH values in plants such as roses, camellias and some native plants when they are grown in soils not acidic enough for them.
Lawns in tropical areas can be more deficient in iron.
Iron deficiency is commonly seen during the wet season as the availability is reduced at high pH levels.
