Milorganite Fertilizer Review [2023]

Milorganite Fertilizer is one of the most popular fertilizers available on the market. Having good soil is absolutely ESSENTIAL for having a beautiful lawn. You can spend thousands of dollars on a state of the art lawn mower to do everything for you including your taxes and brew a cup of coffee but if you have unhealthy soil, sorry buddy! IT AIN’T GONNA HAPPEN!

How do you get good soil you ask? One of the best ways is to fertilize! Let’s check out one of the best products:

Why we review lawn tools

The reason we started this website in the first place was because we had so much trouble trying to find reasonable, understandable, honest reviews for lawn equipment. And it’s not cheap! After hours and hours of research, trying products and returning them, and messing up our yards – we started this site.

We go to extreme measures.

As people who had to learn the hard way, we want you to know exactly what you are signing up for before you purchase a piece of equipment. That’s why we are committed to providing honest, easy-to-understand reviews that mean something.

Its reputation is great for a reason

Milorganite is an OG of the fertilizer world. This stuff has been around almost 100 years and there’s a reason! It works.

Essentially Milorganite is a bunch of dead microscopic bug things that ate a bunch of crap out to the water in Lake Michigan. The company takes these little bug things and kills them, then dries them out and packages them in pellet form. (Super dumbed down version but that’s basically it.)

These dead bugs are PACKED with nutrients that are like Wheaties for your lawn, flowers, shrubs, trees, vegetables, etc. Like the Frank’s Red Hot commercial says, “I put this S** on everything!” Just don’t eat it. Well actually you kind of can eat it because you can use it in your vegetable garden. But don’t eat the actual pellets, silly. 

It’s also great for use during the summer fertilizing season.

Is Milorganite fertilizer safe?

This stuff is safe to use! Not only has it been around longer than the dinosaurs, it’s also subject to strict environmental control regulations. It complies with all the state, local and federal regulations. There is essentially nothing fake in this product, no synthetics, salt or other mined resources. It’s basically just dead microbes. Because it has nothing added to it (LIKE SALT) it won’t burn up your yard or harm newly planted landscaping.

It’s also pet friendly! I can’t tell you how many times my wife has worried about our dog, Bella, eating up the fertilizer I apply to the yard. (And honestly she does). I can sleep easy at night knowing this stuff won’t poison our family pup. It might make your dogs stomach hurt or ruin a carpet if ingested but it shouldn’t kill them.

How does it work?

Milorganite is a slow releasing fertilizer, so in addition to not burning up due to salt additives, it also won’t damage plants because it doesn’t decompose into your lawn all at once. It continues feeding for 2 to 3 months after application.

This slow release system also is good for mother nature. Unlike some fertilizers, the slow release does a pretty good job at preventing it from being released into the groundwater. Like I said earlier, the key to a healthy lawn is healthy dirt! 

Milorganite Fertilizer: Application

To apply Milorganite Fertilizer on your lawn, I highly recommend using the Scotts® Turf Builder® Edgeguard® DLX Broadcast Spreader. Depending on your lawn size, dump a bag of this stuff into the hopper of your spreader and adjust the disbursement setting on the edge of the hopper to whatever the bag recommends. It’s a big orange knob. You can’t miss it.

Then pull the handle on the broadcast spreader and walk around your yard just like if you were mowing. Maybe a little more spread out than you would if you were mowing but in a similar pattern. Just make sure you’re getting some overlap of pellets on every pass.

Similar process as Scotts turf builder

A 32 lb bag should cover a 2,500 sq ft lawn. My yard is about 10,000 sq ft so I need about 4 bags per application. 

You really should fertilize four times a year if you want that deep rich green lawn. Think a meadow in Ireland or something. This stuff will make your lawn look GOOD. You really can’t use too much unless you go crazy with it. Remember it’s slow releasing so I tend to use a little bit more than they recommend. I apply on the holiday schedule, Easter, Memorial Day, Labor Day and Halloween. But it depends on where you live. Check out the calendars below to help you out.

Milorganite Fertilizer: Recommendation

Before I’d tell you to go buy a new mower, I’d tell you to buy this stuff. It truly is the foundation you’ll build your lawn kingdom on. You simply cannot have a lush, beautiful lawn that makes your neighbors do a double take without healthy soil. Trust me. You’ve got to be religious about fertilizing. Four times a year. Every year. FOREVER.

The certainties in life should be death, taxes and fertilization. A bag of it will run you about $30 on Amazon or at Home Depot. So for you Dave Ramsey budgeters, plan on spending about $240 a year on it. So yes, I would absolutely recommend this stuff to anyone wanting a show stopper lawn.
