How to Spot Iron Deficiency in Your Plants
If there is not enough iron available to your plants then it will undergo chlorosis. Chlorosis is the yellowing of the leaves of a plant. In iron deficiency, the youngest leaves are effected. This is occurs in the younger leaves first because iron is not a mobile element in the plant. The young leaves cannot draw iron from older leaves.
What Causes Iron Deficiency
As I said earlier, certain low desert areas are more prone to plants with iron deficiency. This is because calcium carbonate deposits occur in these desert soils. This results in a high pH soil that is not conducive to iron uptake by the plant.
Other Macro and Micronutrients
As you may know, there are many other macronutrients and micronutrients that are important to proper plant growth. The macronutrients is split up into primary macronutrients and secondary macronutrients.
What plants have iron deficiency?
Common plants that frequently show iron deficiency include azaleas, gardenias, waxleaf ligustrums, cleyeras, wisterias and dogwoods. Left photo: Northern pin oak mistakenly planted for a Shumard red oak. Side by side placement with a true Shumard red oak allows you to see how pin oaks fare in Texas’ alkaline clay soils.
Where does iron deficiency appear on a tree?
1. Iron deficiency (chlorosis) will always appear on the newest growth (leaves at the growing tips of the branches) first.
Why does iron deficiency happen?
Why iron deficiency happens…. Plants take iron into their systems from the soil through their roots. However, it must be soluble in water for that to happen. Under alkaline conditions iron converts to an insoluble form. That’s why iron deficiency is far more common in the western 75 percent of Texas (from I35 westward) than it is in East Texas.

But it’s most prominent on the older leaves farthest from the growing tips. Drought symptoms on shade trees in summer. Older leaves’ veins may turn yellow (mulberries), or entire leaves (many species) may turn yellow overall, and leaves will fall prematurely.
What is the role of iron in plants?
Iron is a soil-borne nutrient element that plants use in the creation of chlorophyll. Since almost all life depends on chlorophyll, iron is rather critical to us all. Here are ways first to identify iron deficiency, then to deal with it.
Can you use iron to acidify soil?
You simply will not be able to apply enough iron to keep them going. • Use combination iron/sulfur materials to supply soluble iron and to help acidify the soil via the sulfur. Note that your plants don’t necessarily need the sulfur. They just need the effects the sulfur has in lowering the soil pH.
Do you need iron to grow a shade tree?
Do not attempt to grow medium-sized and large shade trees that need a great deal of iron if you are in an area with alkaline soils and irrigation water. That list includes slash and loblolly pines, water oaks, willow oaks, pin oaks, cherry laurels, Savannah and American hollies and its hybrids such as East Palatka.
How to treat iron deficiency in plants?
Iron chelate sprays provide a short-term remedy for iron deficiency. Mixing and application depend on the product and type of plant. For example, you should dilute 1 teaspoon of 10 percent iron chelate in 1 gallon of water for rhododendrons and other ornamental plants, recommends Miller Chemical and Fertilizer Corporation. If your plant tolerates a test spray on a small area, thoroughly spray the plant's surfaces. You can lightly mix 6 to 12 tablespoons of iron chelate in every 100 square feet of garden soil at planting time or apply as side dressing after plants emerge. Do not use iron chelate with horticultural oils or lime sulfur fungicide.

Why do plants need iron?
Iron is one of many soil micronutrients that plants need in small quantities for growth and development. Plants need iron to produce the green pigment chlorophyll, which is essential for growth and for producing food and energy for the plant. Soil pH, poor drainage and other factors may cause iron deficiency in plants.
How to lower pH of soil?
Compost can also improve drainage and iron availability in waterlogged soil. Nitrogen fertilizers that contain ammonium sulfate or urea can slightly lower soil pH. For example, 10 pounds of 21-0-0 ammonium sulfate fertilizer will lower a 7.3 soil pH to 7.2. Do not add more nitrogen to the soil than the amount recommended for your specific plants.
What are the symptoms of iron deficiency in plants?
Symptoms for Iron Deficiency in Plants. The most obvious symptom of iron deficiency in plants is commonly called leaf chlorosis. This is where the leaves of the plant turn yellow, but the veins of the leaves stay green.
What Does Iron Do for Plants?
Iron is a nutrient that all plants need to function. Many of the vital functions of the plant, like enzyme and chlorophyll production, nitrogen fixing, and development and metabolism are all dependent on iron. Without iron, the plant simply cannot function as well as it should.
Why are my plants yellow?

So it is important to correct iron chlorosis in plants. Let’s look at what does iron do for plants and how to fix systemic chlorosis in plants.
How does leaf chlorosis start?
Typically, leaf chlorosis will start at the tips of new growth in the plant and will eventually work its way to older leaves on the plant as the deficiency gets worse. Other signs can include poor growth and leaf loss, but these symptoms will always be coupled with the leaf chlorosis.
Why can't plants get iron from clay?
The lack of organic material is actually the reason that a plant cannot get iron from clay soil. There are trace nutrients in organic material that the plant needs in order to take the iron into its roots. If clay soil is causing iron chlorosis, correcting an iron deficiency in plants means working in organic material like peat moss ...
What does it mean when the pH of soil is over 7?
Have your soil tested at your local extension service. If the soil pH is over 7, the soil pH is restricting the ability of the plant to get iron from the soil. You can learn more about lowering soil pH in this article.

What does the middle number on fertilizer mean?
The middle number represents phosphorus – for more information, check out my article explaining the numbers on a fertilizer package. If you think phosphorus is too high, find a fertilizer with lower (or zero) phosphorus content. Likewise, excess calcium can prevent iron uptake in a plant.
What can block a plant from absorbing another nutrient?
Too much of one nutrient can block a plant from absorbing another. For example, excessive amounts of phosphorus can prevent iron uptake in a plant. This can occur if you use a garden fertilizer with high phosphorus content.
How to fix iron deficiency in plants?
The solution for iron deficiency in plants is to make more soluble iron available to the plants, which is best done by treating the soil. In particular, by altering the pH to make soil more acidic so that more nutrients are available in soluble form for the plant to absorb. Chelated irons mixed into the soil are a good solution to enrich available ...
Why is iron insoluble in soil?
The higher the pH, the more likely it is the iron molecules can latch onto other minerals, mainly calcium and phosphorous, therefore, making them insoluble, so while so ils can be rich in iron, because they’re insoluble, plants can’t absorb them . It’s for this reason soils need ...
What type of iron is used in soil?
The type to use (and the cost) will be determined by your soil acidity. The three types of chelated irons available include: Fe-EDTA. Fe-DTPA. Fe-EDDHA. The most stable and most expensive type is Fe-EDDHA, which is stable in alkaline soils with a pH 9 and above.
Why do plants die prematurely?
Without chlorophyll, plants lack oxygen and since photosynthesis is hindered, the plant won’t be able to get its energy from sunlight. Without knowing how to fix iron deficiency in plants, the lack of iron will eventually cause affected plants do die prematurely.
What is the yellowing on the leaves of a new plant?
However, the earliest sign to look for is the yellowing on the veins of new leaves as those will lose their green first. This is called interveinal chlorosis and is the first indication of a nutritional imbalance.
Why are my leaves yellowing?
An iron deficiency in plants is recognized by yellowing leaves (there are other common causes, which I cover here ). This happens when iron is lacking as plants can’t produce chlorophyll, which is what gives the plants the green color on their leaves and is also used to carry oxygen throughout the plant. Without chlorophyll, plants lack oxygen and ...
Can fertilizer help with iron deficiency?
While it is possible to try to fix iron deficiency in plants by using a fertilizer rich in iron, it’s not guaranteed to rectify a mineral imbalance. For plants to absorb iron from the soil, the iron needs to be in soluble form.
