Today I am going to expose one of the secrets to have a deep green lawn. You guys know you have to fertilize your lawn in order for it to be green, but you should also know there are certain types of fertilizers that do different things. Enter: Iron for lawns.
Iron is considered a micro-nutrient in the lawn. It is not necessarily essential, but a lack of it can make the lawn look pale or even yellow. (chlorosis) But for our purposes here, we want to use iron to give the lawn that deep blue/green coloring.
Yep, that’s right guys: iron is what makes Kentucky Bluegrass and other lawn grasses blue. THAT will surely help you stand out from your neighbor won’t it? Of course it will!
Now you need to make sure you get chelated iron for your lawn. Chelated means the iron is in a suspended state where it can be readily absorbed and use by grass plants. I say this because iron can bind up in soil where it can’t be utilized. If you get chelated, you will be just fine. The best source of chelated iron is milorganite. It’s organic and contains chelated iron! Awesome!
Be Careful With Iron – Ironite
If you decide to go with another type of iron for your lawn like Ironite, you need to be careful. Now, don’t get me wrong, Ironite works VERY well. The issue is, however, that Ironite have a few drawbacks. They are:
1) ironite can stain driveways, sidewalks, siding, decks, etc
2) you can over-apply iron and cause the lawn to turn grey or even completely “blow out” where the blades thin out completely
3) ironite is not slow-releasing and in my opinion won’t last as long in the lawn
Seriously guys, if you want iron in your lawn, use Milorganite. There are so many more advantages to it (like a boost of nitrogen as well) and it is error-proof… always important I think!
