Using Iron on my lawn

Iron is an essential micronutrient for lawn and grass growth. It plays a vital role in the process of photosynthesis, which is the process by which plants convert light energy into chemical energy. Without enough of it, lawn and grass can become stunted and yellow, leading to a patchy, unappealing lawn. Here are a few benefits of using iron for your lawn and grass.

First, iron helps to improve the overall health and colour of lawns and grass. Iron is responsible for the production of chlorophyll, which is the pigment that gives plants their green colour. Iron deficiency can result in the yellowing of the leaves, which can make your lawn look unhealthy. By providing your lawn with enough iron, you can help to keep it looking lush and green.

Second, it helps to improve the root growth of lawns and grass. Iron is an important component of the cell walls of plants, and it helps to strengthen them. Stronger cell walls mean that the roots of your lawn and grass will be able to absorb more water and nutrients, which can lead to better overall growth.

Third, iron can help to improve the tolerance of lawn and grass to stress. Iron is involved in many of the processes that plants use to cope with stress, such as drought and high temperatures. By providing your lawn and grass with enough iron, you can help to improve their ability to survive and thrive in stressful conditions.


To ensure that your lawn and grass have enough iron, you can apply iron fertilizers to the soil. It is typically recommended to apply iron fertilizers twice a year, once in the spring and once in the autumn. You can also add iron to your soil by using chelated iron, which is a type of iron that is easily absorbed by plants.

In conclusion

Iron is a vital micronutrient for healthy grass growth. It plays a crucial role in the process of photosynthesis and helps to improve the overall health, colour, root growth and tolerance of lawn and grass to stress. Incorporating iron through fertilizers or chelated iron can help to maintain a lush and healthy lawn. Keep in mind that a healthy lawn not only looks good but also benefits the environment as it helps to prevent soil erosion, improve air quality and also cool down the temperature of the surrounding area. It is important to test the soil regularly to check the iron levels and adjust the fertilization accordingly to avoid over or under fertilization.
