Best Liquid Iron for Lawn

Do you ever wonder why your neighbour’s lawn is so luscious and verdant?

Well, chances are it’s because they are using an iron fertilizer.

Iron is an important nutrient for plants since it plays a huge role in the synthesis of chlorophyll (the green pigment responsible for photosynthesis in plants) which is vital for the survival of a plant.

Turf that has a low amount of iron is very likely to experience mottled yellow areas as well as a condition known as iron chlorosis. In this condition, the plant starts to turn yellow and brown and if left untreated can die.

Iron Deficiency

Iron deficiency can occur for a few different reasons such as high pH level of the soil, or because of high amounts of other nutrients available in the soil such as zinc, nitrogen etc. 

If your lawn seems like it is starting to lose its will and experiencing conditions such as iron chlorosis, lacklustre symptoms or even dormancy then it’s the time for you to consider using an iron supplement for your lawn.

Iron will not only make your lawn look more appealing but will also enhance your turf’s ability to tolerate heat and droughts, as well as resist diseases etc. Iron can be used for moss control as well.
