In the world of advanced technology, every gardener can use chelated iron, a water-soluble plant supplement that is very easy to apply.
Without a doubt, iron is a significant nutrient for plants since they use it for most vital functions like nitrogen fixation, development, and chlorophyll as well as enzyme production.
As a result, plants will not be able to function properly when they are lacking iron or nutrient supplementation. In this view, chelated iron becomes an excellent solution for all.

What Is Chelated Iron for Plants?
Formulated to make iron soluble in water, this is a kind of supplement for use in agricultural purposes.
This soluble iron complex typically comes in the form of dark-colored powder and may cause a mild irritant to eyes, skin, and the respiratory membranes in some people.
Fertilizer consisting of this iron complex is among the most well-known and practical approaches to deal with chlorosis.
In horticulture, such fertilizer can be blended with other nutrients or plant food products. Users may refer to it as sequestered iron and use the good as a tonic.
Those who practice ornamental horticulture will appreciate this soluble iron as well as it makes an excellent feed for plants with calcareous soils.
Why Chelated Iron Is Worth to Consider for Plants?
The main reason is that some plants may suffer iron deficiency due to the lack of this compound in soil.
It may happen due to the soil consist of too much clay or seizes a very high pH. Overly damp or compacted earth can also result in a lack of iron.
You can practice a soil test to diagnose chlorosis. Consider contacting a nearby agricultural extension center to help with this issue.
Remember that they may take leaf samples as well to decide what mineral, nutrient, or micronutrient is missing in your case.
The Symptoms of Iron Deficiency
Yellow leaves between the deep green veins typically hint at iron deficiency in plants. They may have a spidery look due to this condition too.
Besides, plants and leaves with iron deficiency tend to lack that ‘healthy green’ appearance.
Without any treatment, the foliages are getting whitish and begin to die, causing stunted development of the whole plant. This condition is pretty wearisome to a gardener, particularly with the unpleasant whitish or yellow foliages.
The Treatments of Iron Deficiency
As mentioned above, the chelated iron powder can help with this issue. However, always keep in mind that the best solution to chlorosis is preclusion.
In this view, it is important to discover the fundamental cause and focus on treating the case to avoid the same matter from occurring later.
Generally, you can apply iron in chelated form or as ferrous sulfate. It is rather a cheap and easy solution as the application is mainly through spraying.
Iron chelates make a good choice since they have stabilized ions to prevent the solution from oxidizing. However, different iron chelators will result in dissimilar potency depending on their given pH levels.
How to Make Chelated Iron
You can make this supplement by incorporating agents to the iron and different elements used in the process will influence how effective the result is.
For instance, if the formulate includes EDTA, you will get a less strong product that is appropriate for fixing iron deficiencies in soils with a pH of lower than 6.5.
Meanwhile, DTPA is a more suitable chelator for alkaline soils. It can generate a medium-strength supplement as long as the pH is not higher than 8.0.
If you need the supplement for soils with a very high pH, EDDHA makes the best material to use as it can offer the strongest result.
Keep in mind that the stronger the chelated iron, the pricier it will cost you. The supplement itself is available in some different forms including powders, pellets, granules, and spikes.
Chelated Iron Powder
This is the most common form of this iron supplement. Along with granules, powders are soluble, so simply mix them into the water to make foliar sprays.
Then, spray the solution to the leaves of the affected plant. After a few applications, the foliage may show improvement and return to their healthy, green appearance.
Chelated Iron Liquid
In addition to the powder forms, you may also find the product in the form of liquid in the market. Despite the difference in forms, both liquid and powder supplement typically require you to mix them with water before each application.
If you use a quart hose-one sprayer, mix one pint of the product with equal water volume. This measurement should be enough to cover a 500 square-feet area.
FAQ Regarding the Use of Chelated Iron
You probably still have several things in mind after discovering the importance of this iron supplement for plants.
As a gardener, you typically start to need this supplement when recognizing iron deficiency in plants. However, it will be useful to deal with alkaline soils that are very high in pH levels.
How do You Apply Chelated Iron for a Lawn?
Depending on how wide your lawn is, the amount of the supplement needed will be different. Some horticulturalists believe that applying two pounds of this iron supplement per acre is sufficient to turn the grass greener.
Nevertheless, the green may last several weeks only in cool, damp weather and a few months in dry temperature. For this reason, other horticulturalists recommend applying the foliar spray to the lawn every twice a month to maintain the result.
Can You Find Chelated Iron on Home Depot?
Indeed, you can easily find this supplement on Home Depot especially under the section of Plant Food & Fertilizer. Generally, you should not feel the need to purchase the most costly product, especially if it will be used as a foliar spray.
In this case, the least expensive one is likely to perform equally well since the strength is not very significant in foliar spray.
Can You Use Chelated Iron for Trees?
Aside from plants, you can generally take advantage of this iron supplement to relieve chlorosis in trees.
Try to apply the supplement in the soil during spring before your tree starts to grow. For foliar application, do so on a cool, dry, cloudy day.
In short, chelated iron offers a practical, quick solution for any plant or tree that suffers from chlorosis although it does not provide a permanent result.
