Why Organic Fertilizers?

Milorganite is a popular organic fertilizer for many reasons. First off, it is a slow-release nitrogen fertilizer. This allows you to apply nitrogen fertilizers less frequently, and the slow steady release provides nutrients for up to 10 weeks.

Organic fertilizers like Milorganite are also non-burning. This means it is safer to use during summer months than synthetic fertilizers. The slow-release nitrogen also aids in the non-burning benefits.

These also provide a good source of iron. Iron, of course, is important to provide that deep dark green, picturesque grass that all lawn care addicts yearn for. And unlike liquid iron sulfate products, Milorganite will not stain concrete driveways, patios or walkways.

Lastly, and perhaps most importantly, Milorganite (and some of these alternatives fertilizers) contain a lot of organic matter which helps feed the soil. When the soil is nourished, it feeds and activates soil microbes.

Frequently Asked Milorganite Questions

What is Milorganite?

When to use and apply Milorganite?

Depending on where you live and what your lawn care program consists of, but for cool season lawns, you can use Milorganite as frequently as 4-6 times per year. For Massachusetts Zone 6 for example, Lawn Phix suggests five applications between May-September.

Can you use Milorganite with other Fertilizers?

Depending on how much Nitrogen you are looking to put down per application and per year, Milorganite is safe to use with other N-P-K fertilizers and supplements. For example, Lawn Phix suggests using Milorganite in conjunction with a starter fertilizer, lime and Kelp4Less when overseeding in the fall. Use our Nitrogen Calculator to help calculate the amount of Nitrogen you’re applying.

Where can I buy Milorganite?


Milorganite can be found at some select Home Depot, Lowe’s, and Ace Hardware locations. You can also check your local nurseries, lawn and garden centers, and hardware stores. Milorganite can also be found on Amazon.com and other e-commerce websites. Sometimes Milorganite can be in short supply. You will want to look for some alternatives just in case you can’t find it, or need something cheaper within your budget.

  1. Since this list does not show Michigan, you can get Ideal EQ Natural Fertilizer 4-3-0. at Menards. It is sold as Menards Natural. When I checked the SDS, it was for Ideal EQ Natural Fertilizer.
