How Often To Apply Liquid Iron On Grass

Fastest Lawn Green Up | Iron Application

The results of a good soil test will not only measure your soils iron content but can also guide you as to the quantity to be applied and how often. Of course, youll always want to follow label instructions to avoid overdosing. Typically, 30 days in between each application is recommended. But, here are some solid rules-of-thumb to follow:

  • If your lawn is more green than yellow, 3-4 applications per growing season should be sufficient.
  • If its more yellow than green, either a higher dose per application or higher number of applications may be required to achieve a uniform greening effect.

What Does Chelated Iron Mean

Iron, in its pure form, isnt of much benefit to plants because it naturally rusts when exposed to water and oxygen. In small qualities, this wouldnt harm your lawn. But, if rust content is allowed to build up over time, it may lead to iron toxicity in the soil. Iron in chelated form is far more beneficial as it is processed using the addition of non-metallic ions that create a protective barrier between the iron in your soil and oxygen. This prevents it from rusting and becoming a nuisance.

The chelating process also keeps iron from separating and leaching out. Allowing it to remain where it is most accessible to the roots of your lawn. When choosing which brand of chelated iron to use, youll see listings like Fe-DTPA, Fe-EDDHA, Fe-EDTA, Fe-EDDHMA, and Fe-HEDTA. All of which are common formulas in some of the best types of liquid iron for lawns.

When To Apply Iron To Lawns

Determining when to use iron supplements on your lawn can be a challenge. The best times will vary based on the type of supplement you choose to use, as well as your integration method.

On average, its safe to use both synthetic and organic supplements up to four times a year. When you use organic supplements, its best to seed your lawn with iron just as the weather starts to warm up in spring. Youll want to use synthetic supplements shortly after the final frost of the season, as it tends to work its magic quickly.

If youre not sure which supplement to use on your lawn or how to best integrate it into your lawn, a professional lawn care team, like MetroGreenscape in Charlotte, can give you guidance.

Liquid Iron For Lawns

Plants, including grass, use iron to support the chlorophyll production process, and low iron levels in the soil means the grass may not have enough of this mineral nutrient to produce its green color. Grass that is deficient in iron will green right up with an application of a liquid or granular supplement.

If you think your grass may not be getting enough iron, inspect the blades to be sure pests, disease arent stressing them, or over watering, then do a soil test to be sure the lawn isnt nitrogen deficient.

How To Lower Your Lawns Iron Levels

When your lawn has been given too much iron, it can be difficult to lower these iron levels directly. What you can do is add one or two substances that can support the health of your grass and soil while the iron is dealt with naturally. Below are the best 3 options for soil amendments while your grass is recovering from an overdose of iron.

What Do You Use Iron Sulfate For

Iron sulphate has several uses and can be applied to your lawn throughout the growing season to bring energy and vitality to your lawn.

Lawn-bound products are usually supplied in powder or granulated form and are often included in general fertiliser mixes. The principal reasons for adding iron sulphate to your lawn are:

  • Boosting the nutrient levels of your lawn after the winter
  • Providing your lawn with a fresh, deep green glow
  • Improving resilience before scarifying

TIP: An accurate measure of iron sulfate kills moss in as little as four days.

Why Add Liquid Iron To Lawns

If that yellowish haze is spreading across your lawn, a good soil test will determine how much iron is naturally present. It may turn out that theres plenty of iron in the soil but the pH level is too high. This would actually block your lawns ability to absorb that iron, as well as water and other nutrients. Lowering the pH will allow for better access.

If testing shows an iron deficiency though, this may be due to soil nutrients leaching out over time. This is particularly common in areas with heavy rainfall. Resulting in a substrate not fertile enough to support healthy growth. Replacing it with the right product will not only improve the health of your lawn and soil but will also lead to an increased vibrancy in turf color without all the excessive growth that often follows high doses of nitrogen.

Types Of Iron Fertiliser

How To Mix & Apply Iron Sulphate To Your Lawn

There is more than one type of iron fertiliser for lawns so before you start applying, it is a good idea to understand the difference between these. This will help you to make a more informed decision on the best supplement for your lawn.

  • Ferrous sulphate is a common type of iron fertiliser that is also one of the most affordable. However, this is typically only suitable for lawns with a pH lower than 7, otherwise, it wont have much of an effect. It contains around 20% iron.
  • Chelated iron for lawns is a compound that stabilises metal ions and protects the lawn against rain and oxidisation. These compounds contain various things including Fe+3, sodium, ammonia and amino acids or citrate.
  • FeEDTA is a type of iron fertiliser that does not work in alkaline lawns owing to its ineffectiveness in pH below 6.5.

Apply Lime To The Soil To Treat Iron Toxicity

Apply lime to your lawn to adjust the soil pH. Lime not only makes the soil more alkaline but also adds other micronutrients like calcium and magnesium. Remember, lime comes in different varieties, which is why its important to know which one suits your application. Also, dont apply too much lime on your lawn as it can kill the grass. Prevent this by adding elemental sulfur or sulfate-containing chemicals to the lime.

When treating your grass for iron toxicity, its vital to remember that iron is an immobile nutrient. It might take more than three weeks for the symptomatic leaves to revive their green color.

Here are other treatments for iron toxicity you can try:

What Does Iron Do To Your Lawn

Applying iron to your turfgrass can make your lawn healthier. Additionally, it will deepen its green, which always has an appealing aesthetic effect. Indeed, if your turf looks discolored or yellow, iron deficiency might be the cause.

Contrary to fertilizers, iron supplements do not boost growth or require the application of extra moisture. Instead, they will improve the overall health of your turf.

Iron should be essential to your turfs maintenance when growing fescue or bluegrass. Indeed, it will help these cold-season grasses to stay green even during the summer months.

Additionally, iron can contribute to removing moss from your lawn. While it isnt necessarily negative to have it around your garden, moss might lead to root rotting and other diseases. Preventing it from spreading on your lawn is always a good idea.

You can find two iron supplement types on the market: synthetic and organic. The first is usually less expensive and is effective faster. However, they come with the side effect of burning your lawn .

Also, such chemicals might stain your grass , which might not be ideal. Orange stains might harm the aesthetics of your lawn if you are not careful when using iron fertilizers. So, keep that in mind before deciding to apply a synthetic product.

On the other hand, organic iron fertilizers might take more time to have an effect. However, they wont harm your turf. Additionally, they will gradually release their nutrients, which will result in better absorption.

Why Do Plants Need Iron

How To Control Iron Deficiency In Your Lawn

Plants and people both need iron. In humans, the mineral forms part of the haemoglobin in your red blood cells which transports oxygen to your brain, your muscles and your internal organs. In plants, iron is needed, amongst other things, to make chorophyll. Chlorophyll is what makes the leaves green but physiologically it is used to harness sunlight to make sugars. In short, its how plants feed themselves. Plants also use iron to make some of the enzymes and hormones that control everyday functions within their cells.

A person who lacks iron in their system is said to be anaemic. More often than not their skin will be pale and theyll feel tired, lethargic and sometimes even breathless. If your lawn is iron deficient, the condition is known as chlorosis. Leaves will be pale and take on a yellowish tint in between the veins. In extreme cases, the leaf blades might be a bit floppy and lacklustre. And as with any sort of malnutrition in lawns, the plants will be more susceptible to pests and diseases.

Chelated Iron Fertilizer For Lawn

The most common form of iron fertilizer for grass is water-soluble chelated iron. Chelated iron contains iron or iron and aluminum paired with sulfate. Examples are ferrous sulfate, ferric sulfate or ferrous ammonium sulfate.

Penn State University horticulturalists say applying 2 pounds of chelated iron per acre will typically cause the grass to turn greener. The green may last only a few weeks in cool, wet weather and for several months in cool, dry weather.

Next, Ill be sharing my top three picks for the best performing chelated liquid iron products out of the many that Ive tested. Some come in a concentrated form that needs to be diluted with water. While others come pre-mixed and ready to go. Both can be evenly applied across your lawn, as you walk back and forth, using your hose and a quart-sized sprayer attachment. You will want to wear protective clothing though, as chelated liquid iron can cause skin irritation.

Concentrates will typically advise mixing anywhere from ½ teaspoon to 2-3 ounces with a significant amount of water prior to use It would seem that the smaller the amount to be diluted, the longer the jug will last. Making it seem more economical. Yet, some that required diluting higher amounts actually performed better. Focusing on value-for-money is going to be your best bet.

Research Demonstrates Milorganites Ability To Green

We conducted independent research a few years ago to ensure that, despite any changes in the iron guarantee, Milorganite continues to provide homeowners the outcomes they expect lawns that are healthy, with a long-lasting, deep-green color.

We studied both northern and southern grasses to determine how various amounts of iron and nitrogen in Milorganite affected the greenness of lawns. The study of northern grasses was conducted through the University of Wisconsin Madison, Department of Soil Science.

Two measures were used to evaluate how green the lawn was for each fertilizer mix: one electronic and the other visual. Under the conditions of the study, both measures were found to be statistically similar to the Milorganite mix with 5.1% iron, as well as the mix with 2.3% iron . The different levels of iron “…did not significantly affect the color response of the grass.”

Average Color Index

4066.8

A 2015 study conducted in Florida by George H. Snyder, Ph.D. compared Bahiagrass grown with various fertilizer treatments, including three of Milorganite with varying amounts of iron2%, 2.7%, and 4%. The year-long study concluded that Throughout the study, no differences in leaf appearance or growth were observed among the three Milorganite sources.

Planting Warm Season Grass In Cool Regions And Vice Versa

If you plant warm-season grass in a cooler climate, chances are your iron application method might backfire, and vice versa. Therefore, its best to stick to grass that suits your geographical location and climate.

There are about a dozen varieties of grass species for lawns, many of which contain a mixture of two or more varieties. They fall into two categories:

  • Warm season grasses like Bermudagrass and St. Augustine grass thrive in warmer climates like the South and Southwestern states.
  • Cold season grasses like Tall fescue and Kentucky bluegrass prefer cooler climates such as the Pacific Northwest and Northeast.
