Sunniland vs Milorganite: Which is the Best Fertilizer

Milorganite and Sunniland are two popular fertilizer brands that homeowners and gardeners often compare when looking for the best lawn care solution. 

What is Milorganite?

Milorganite is an organic fertilizer made from heat-dried microbes that have digested organic matter in wastewater. 

It is a slow-release fertilizer that provides essential nutrients to your lawn, including nitrogen, phosphorus, and potassium. 

Milorganite has been trusted by homeowners and professionals for over 90 years and is known for its ability to improve soil structure and promote healthy root growth.

What is Sunniland?

Sunniland is a family-owned company based in Florida, offering a range of lawn and garden products, including fertilizers, insecticides, and herbicides. Sunniland’s fertilizers come in both organic and synthetic options, providing a variety of choices for homeowners and gardeners. 

Their products are specifically formulated for the unique soil and climate conditions of the southeastern United States.

Comparing Milorganite and Sunniland: Key Differences

Nutrient Content

One of the main differences between Milorganite and Sunniland fertilizers is their nutrient content. Milorganite is primarily composed of nitrogen, phosphorus, and potassium, with a typical N-P-K ratio of 6-4-0. This means that it contains 6% nitrogen, 4% phosphorus, and 0% potassium. 

On the other hand, Sunniland offers a variety of N-P-K ratios depending on the specific product, allowing you to choose the best option for your lawn’s needs.

Organic vs Synthetic

Another key difference between Milorganite and Sunniland is the nature of their ingredients. Milorganite is an organic fertilizer, made from the byproducts of wastewater treatment. 

This means that it is environmentally friendly and safe to use around children and pets. Sunniland, however, offers both organic and synthetic fertilizer options, giving you the choice between natural or chemically-derived nutrients.

Application and Release Rate

Milorganite is a slow-release fertilizer, meaning that it releases nutrients gradually over time. This helps to prevent nutrient runoff and promotes steady, healthy growth in your lawn. 

Sunniland fertilizers, on the other hand, come in both slow-release and quick-release options, allowing you to choose the best option for your lawn’s needs.


In general, Milorganite tends to be more expensive than Sunniland fertilizers. 

The price difference may be offset by the long-lasting effects of Milorganite’s slow-release formula, which can reduce the need for frequent reapplication.

Comparing Milorganite and Sunniland: Similarities


Both Milorganite and Sunniland fertilizers are effective at promoting healthy lawn growth and improving soil structure. 

By providing essential nutrients like nitrogen, phosphorus, and potassium, these fertilizers help to support strong root systems and vibrant, green grass.

Ease of Use

Both Milorganite and Sunniland fertilizers are easy to apply, with clear instructions provided on the packaging. 

They can be applied using a broadcast spreader, drop spreader, or by hand, depending on the size of your lawn and your personal preference.


Milorganite and Sunniland products are widely available at home improvement stores, garden centers, and online retailers. 

This makes it easy for homeowners and gardeners to find and purchase the right fertilizer for their needs.

The choice between the two largely depends on your personal preferences and needs. If you are looking for an organic, slow-release fertilizer with a proven track record, Milorganite may be the best option for you.
