Buying Guide

Lawn Star Liquid Iron

When you notice discoloration of your lawn, it means your turf is iron deficient, and this is the right time to feed your lawn with essential nutrients. However, selecting appropriate liquid iron for the lawn is not an easy task. It takes time and energy to find a perfect iron supplement that improves your lawn health and gives it a vibrant look. Here is a guide that will help you find a liquid iron supplement for regaining the natural look of your lawn.

Testing The Soil

The condition of your lawn will tell you about the deficiency of the nutrient. The most common problem one can notice is the decoloration of grass. When the grass turns yellowish or brownish, it gives you an indication that your soil is iron deficient. Depending on the low nutrient, you will decide which supplement to choose. It will also tell you in what amount you need the liquid iron to fulfill its deficiency. It is essential because if you spray too much liquid iron, it may damage your soil, whereas too little iron will not work efficiently.

First of all, you need to test the soil. This step is crucial because it will let you know about the pH level of the soil. For example, liquid iron does not work correctly if the soil is alkaline and has a high pH level. With the soil test, you will be able to know which nutrient is deficient. For soil tests, you will need a testing kit. Take a small amount of soil and check with the equipment.

Once you are done with this test, you can better decide which supplement you need to purchase according to your soil needs. If you do not have a testing kit, you can also visit the testing laboratory. They will analyze the condition of the soil and will tell you the results. They will also give you recommendations regarding purchasing a liquid supplement.

Area of the lawn


Depending upon the size of the lawn, you can buy liquid iron. If the lawn’s area is small, you can have a small size liquid iron. However, if the surface area of the grounds is large, try getting a large gallon of the liquid iron. It will spread in the lawn evenly and will give you effective results after application.

Granular Vs. Liquid Iron

It is better to purchase liquid iron than granular iron because liquid iron absorbs in the ground quickly and reaches the roots for better root development. It also gives you faster results, and you will notice the rapid greening and better health of the grass within 24 hours. Furthermore, it distributes in the soil evenly and has a versatile application. It is a bit expensive as compared to granular iron but has universal applications.

It is compatible with other pesticides and herbicides and is safe to use for pets and the surrounding area. It causes very minimal irritation depending on person to person. You have to apply several times for the best results. The liquid iron results are for a shorter period than granular iron. However, the liquid iron absorbs instantly in the ground but does not have long-lasting effects on the lawn.

Spraying Method


You can use two methods that can give you better results. Many brands offer liquid fertilizers with a spray bottle that makes it easy for you to sprinkle the liquid iron all over your lawn. It will help you to distribute the liquid iron evenly. The liquid iron will saturate in the ground, and it will help to promote root development. You can also use the irrigation method by mixing the liquid iron with excessive water in the tank and then spraying it evenly on the ground. This irrigation method is easy and time-saving.


Liquid iron protects your lawn from discoloration, chlorosis, and lackluster. This condition of your lawn depends upon the soil’s pH level, higher amount of zinc, or deficiency of iron. For combating iron deficiency, I have reviewed some best products that will help you find a perfect iron supplement depending upon the garden’s need. The top three recommendations are:
