Lawn Maintenance: How to Get a Dark and Green Lawn - Home - Landscaping

Want to know the secret to getting a lawn that's dark and green? Of course, you do! Well here it is in two words: Iron Supplements. This is a common technique used by lawn care professionals. They not only use iron supplements to help give grass that nice deep, bluish-green color, but also use the supplements to help control the growth of moss. If you have the fescue or bluegrass species, you will find iron supplements to be particularly helpful.

Synthetic vs. Organic Iron Supplements

Iron lawn supplements falls under two categories: synthetic or organic. Just as in food and supplements for humans, anything organic will cost you more. Synthetic iron fertilizers usually come in the form of granules and spread over the lawn just like other fertilizers. It's less expensive than an organic iron fertilizer and is fast acting so you should see results fairly quickly (within days). Because it is synthetic, if you use too much of this type of iron supplement, your lawn will turn gray. Also, it has been known to stain concrete driveways. You know that color on rusty iron fences? Well, the same thing can happen to your concrete walkways and driveways if you're not careful when applying synthetic iron fertilizers. These are the downsides to the synthetic iron supplements.

Organic iron fertilizers, on the other hand, take longer to break down. But because they're chelated, the grass can absorb the organic fertilizers more easily. They also contain other nutrients that are good for your lawn. And unlike its synthetic counterpart, you don't have to worry about organic iron fertilizers staining your outdoor concrete areas.

Applying the Iron Lawn Fertilizers

As mentioned before, you need to be careful not to over-apply the supplements, especially the synthetic ones. Follow closely the directions on the package. Overdoing it is just as bad as having an iron-deficient lawn. Also, you should apply the fertilizer during spring time when the weather is mild, around 60 to 70 degrees.

Keep in mind that an iron deficiency may not be the real cause of yellowish-looking grass. So, before you jump to the conclusion that your lawn needs iron supplements, look for more likely sources first, like: Is your lawn getting enough water? Is the lawn lacking in some of the regular nutrients?
