We all treat our lawns and pets like our kids so we want them to grow and look healthy. Don’t we?
And it is healthy when it is glowing in rich green color.
Sometimes you are fulfilling all the basic requirements still the lawn doesn’t seem happy. This is the sign that your lawn needs fertilizer as your plants do not just require water and sunlight but nutrients as well to grow and flourish well.
Milorganite and ironite are two reliable fertilizer we all have heard of. We all know what they are for and how they are used but newbies get confused as they both are 100% effective in doing their jobs.
Milorganite and ironite are two different lawn care fertilizers that are made to serve different purposes.
This brief guide is going to answer all the raising questions in your mind. But let’s get to know milorganite and ironite first.
Milorganite is among the few branded fertilizers that are composed of heat-dried microbes. It is a product of the Milwaukee Metropolitan Sewerage District. The oldest chemical-organic blend that has been around for so many years is known for improving soil quality. Being 85% organic and 15% synthetic, it is safe and easy to use with fewer chances of burning down the lawn.
How is it made?
The company gathers the wastewater from the district and microbes are left in that water when they are done collecting the nutrients that water is sent back to the lake and the microbes are dried and then packed to bring a smile on gardeners’ faces.
How does it work?
It’s a slow-release fertilizer so there would be no immediate results. It releases its content when microbial activity takes place. Microbial activity occurs when soil adequately moisten and its temperature is somewhere between 55 to 85F. When the soil reaches this point the fertilizer starts delivering the nutrients to the deserving parts. It works only when the ideal soil condition is achieved otherwise the nutrients won’t move.
Once applied nutrients will be available for 10 weeks.
What does it do?
It promotes better growth, a healthy root system, and a dark green color.
How many bags of milorganite is enough for you?
You will be needing:
1 bag- 2500 square feet.
5 bags- ¼ acres
6 bags- ⅓ acres
9 bags- ½ acres
12 bags- ⅔ acres
13 bags- ¾ acres
18 bags- 1 acre
Milorganite has a strong bad odor
Milorganite is an organic fertilizer so it does have a noticeable bad odor. But goes away as soon as it is applied to the soil.
Milorganite does not stain
Synthetic fertilizers are disliked for their staining the concrete and pathways part. Since it does not contain salts like ironite, so it does not stain the roadways.
For each below-mentioned case, it needs to be applied at least four times a year to see visible results. But if you are going to ignore the “four applications” advice as your lawn is healthy it is then recommended to fertilize the lawn in the fall season.

Ironite is a popular iron supplement that is used to bring life into the burnt plants. As its name suggests ironite is an iron-rich product that shows its effects by bringing the rich green color out. Manganese, nitrogen, and potassium have been added to give plants a healthy boost. Ironite fertilizer comes into two forms.
- Liquid ironite
- Granular ironite
Both of them are equally beneficial. They are just made to suit your requirements. It works by balancing the PH level which in turn produces noticeable blooms.
Liquid ironite is made for alkaline and sandy soils. The liquid version is ideal for this type of soil as it is easier to absorb liquid fertilizer than the granular one.
Like most of the granular fertilizers, this product starts working as soon as it is spread and watered. It is suitable for both normal to clayey soils.
Can be used on grasses, flowers, trees, shrubs, and vegetables, etc.
At least once a year. Twice or thrice a year will bring fruitful results.
Application Rate: 1 pound per one hundred square feet.
Ironite, not a fertilizer
You may think you are reading a comparison between an organic and inorganic fertilizer but in fact, ironite is not a fertilizer but rather an iron supplement made to fulfill the iron deficiency of both large and small-scale lawns.
Why ironite label was changed, is safe for crops- the truth about this action
The Ironite label was changed a few years back and the company discontinued the original product because the mine that used to supply tailing, an active ingredient, was closed. The “now owners”( Central Garden& pet co.) have changed the product and called ” safe for food crops” in the label.
What you need to know about the “Say no to ironite” slogan?
Several public health and environmental advocates suggest you say “no to ironite” as it contains lead and arsenic. Lead and arsenic are not only harmful to kids but for adults and environments too. So they claim, using such fertilizers in places that are usually crowded with kids, pets, and adults are the biggest and deadliest threat to health. However, the truth about this allegation is yet not discovered but it’s a synthetic product it’s good for the said purpose but needs some interrogation for the concerns.
