Applying Lawn Iron in Spring

By Allyn Paul, filed under Lawn Tips.

Spring, as you know, is a great time to work on your lawn. I think I have blown that idea up with excitement pretty well this season thus far. But one of the coolest things you can do to your grass in spring is give it a little micro-nutrient iron.

Iron is essentially what makes Kentucky Bluegrass “blue” in appearance, but it also deepens the green of most other grass types. In fact, if you want the deepest green color in your lawn, some iron may be in order.

What Kind Of Lawn Iron To Buy

Iron for lawns comes in a couple different forms, but you will probably want to purchase “chelated iron.” That basically means the lawn iron is packaged in such a way as it is readily available for grass roots to absorb. In many cases, iron gets bound or caught up in high pH soils, and, if that happens, it’s useless.

You can get chelated iron for lawns in prepackaged bags from manufacturers such as Scott’s Miracle Grow. Just make sure you get products that do, indeed, contain iron additives. These are usually the safest kinds to buy as the iron is bound in a non-staining encapsulation.

You can also buy straight up iron products like Ironite, which comes in granular and liquid forms. These work well but can stain your driveway, sidewalks, decking, and siding if not properly applied. Even a slight bit of iron on thses surfaces may cause browning or rusting immediately. You must also be careful not to over apply these products because they can turn the lawn a gray color!

Overall, iron is a great way to set your lawn apart from your neighbor’s lawn.

    I applied 30-3-4 a week ago. We just got a nice snow out here in Colorado so I am excited about the moisture. When can I safely apply an iron supplement to my blue grass? Is it too soon since I just applied the 30-3-4?

    Hi frank, if you are using an exclusive iron product, now is fine and it will not interfere, but if your product is also mixed with nitro (like the Scott’s product) then you will need to was another 3-4 weeks.
