Chelated Iron

Iron is one of the most important micronutrients you can provide to your lawn. It will help you achieve that deep, dark green color we all hope for.

It is an important part of any lawn care program.

Ferti-Lome Chelated Liquid Iron + Other Micronutrients

A compliment to any lawn fertilization program, I highly recommend Ferti-Lome chelated liquid iron with micronutrients. 

If your soil test revealed deficiencies in Iron, Zinc, Copper, and/or Manganese, this is an excellent product to help you correct those deficits while greening up your lawn.

You’ll want to dillute with water and apply 16 ounces per 500 square feet, so it’s easy to figure out how much you need if you know your lawn’s square footage.

Southern Ag Chelated Liquid Iron

I’m a huge fan of pretty much everything Southern Ag produces. Their surfactant is the only one I use, and this chelated liquid iron is no exception to their high-quality product line.

For lawns, I recommend mixing 1 fluid ounce per gallon of water, per 100 square feet. When making your purchase, you can estimate that one 16 ounce bottle will cover up to 1,600 square feet of your lawn.

This one goes a little farther than the Ferti-Lome product, but does not contain micronutrients.

LawnStar Chelated Liquid Iron

The LawnStar product line is specifically formulated for turfgrass lawn applications, and their products are excellent.

When applying their liquid Iron you will want to apply 8-16 ounces per 1,000 square feet if your lawn is iron deficient, and 1.5-3 ounces per 1,000 square feet to maintain and green up a lawn that already has sufficient iron in the soil. 

Always mix with plenty of water to get good, even coverage across your yard.

Simple Lawn Solutions Liquid Iron Fertilizer

Simple Lawn Solutions is another great company that makes excellent products that are specifically designed for turfgrass lawns. This product combines high quality chelated iron with liquid nitrogen and manganese. It’s an ideal mix to provide the quick green-up you’re hoping for.

This product has a recommended application rate of 10 ounces per 1,000 square feet of lawns (so each 32 ounce bottle will cover 3,200 sq feet). As always, dilute in plenty of water when you apply.

Monterey Dr. Iron Granules

Not everyone likes to mix and apply liquid products to their grass, and if you’re looking for a granular alternative, this one is my favorite.

While your green-up won’t be quite as quick as a liquid chelated iron, Dr. Iron is my go-to product to provide my lawn with a sustained, slow-release iron boost, or to reduce my soil pH slightly.

I also love that this one is organic! Highly recommended. Apply at 3.5 pounds per 1,000 sq feet.

Key Points to Remember

Iron Application Tips

There are a few important points to remember when applying iron to your lawn. These are:

  1. Be mindful of concrete paths, driveways, and hardscaping. Iron can stain these surfaces, so try to avoid overspray and be ready to hose down these areas immediately after application.
  2. If your soil is not iron deficient, the impact of applying these products may be negligible. It may make sense to do a small test to see what your results will be.
  3. For most lawns, I would recommend no more than 3 applications of iron annually. I personally do one application each year, just before the 4th of July.
