Frequently Asked Questions

Where can I buy Milorganite?

Home users can Find Milorganite at most leading lawn and garden centers across the country (it is America's #1 organic nitrogen fertilizer). Professional users can get Milorganite from our extensive distributor network, often the same supplier for your other soft goods or turf equipment.

How should I set my fertilizer spreader to correctly apply Milorganite?

While settings for the most widely used spreaders on the market are printed on the Milorganite bag, it is not possible to test the setting for every available spreader. We have included Spreader Settings for the spreaders which have been tested and step-by-step Spreader Calibration Instructions to determine the proper setting for spreaders that are not listed on the Milorganite bag.

Is Milorganite safe for children and pets?

Yes. Children and pets can safely go onto areas that have been fertilized with Milorganite. Milorganite meets the most stringent criteria imposed on any fertilizer product for health, safety and environmental concerns. However, use cautionary measures around open bags of Milorganite and store unused portions away from children and pets.

What if my dog eats Milorganite?

Milorganite is not toxic if eaten. Your dog is not facing a “life threatening” crisis that requires medical care or emergency stomach pumping.

How much discomfort your dog has will depend on how much Milorganite was consumed. Dogs that eat a small amount of Milorganite do not show signs of discomfort.

More than a normal food bowl will typically cause gastroenteritis because the Milorganite pellets are coarse, hard and highly abrasive. The abrasion causes inflammation of the stomach and intestinal lining.

Eating too much Milorganite can induce vomiting, which can lead to dehydration, incontinence (stiffness in the hind legs), atrophy, depression and black stools.

To alleviate discomfort, provide liquids, a bland diet, and contact your local veterinarian for instructions on how to manage gastrointestinal irritation. If a veterinarian suggests that the high iron in Milorganite is life threatening, the vet is incorrect about the chemistry. The iron in Milorganite is not soluble and is not available for absorption in the mucosal cells of the small intestine. Milorganite pellets pass through a dog’s digestive system causing discomfort, but without absorption.

If you have further questions, please call (800) 304-6204.

I heard that Milorganite contains heavy metals. Is that true?

Yes, that is true. All fertilizers, both organic and synthetic, contain some heavy metals. In fact, plants need some heavy metals, such as zinc and copper and molybdenum, for normal, healthy growth. Milorganite meets the U.S. Environmental Protection Agency (EPA) "Exceptional Quality", which establishes the strictest concentration limits in the fertilizer industry for heavy metals. Many other common fertilizer products exceed the limits for metal concentrations established by the EPA "Exceptional Quality" standards. Milorganite, though, can be used with confidence for all your fertilizing needs, including use on all types of grass, trees, shrubs, flowers and vegetable gardens.

Can I use Milorganite for my vegetable garden?

Yes. Milorganite is an excellent and safe fertilizer for all plants that grow outdoors, including vegetables and other edible crops. Milorganite is practically goof-proof since it won't burn plants-even if it is over applied.

What does the 5-2-0 on the bag mean?

The 5-2-0 guarantees that Milorganite contains at least 5% Nitrogen, 2% Phosphorous and 0% Potassium by weight.

What is the difference between Organic and ‘Regular’ fertilizers?

Organic nutrients are "stored" in complex organic molecules until soil microorganisms break them down and "release" the nutrients for plant use. Regular synthetic fertilizers are chemical-based and need to be watered in.

Does Milorganite need to be watered in to work?

No. It is not necessary to water in Milorganite for it to work. Milorganite will stay on the soil until it rains or irrigation activates soil microbes that break it down into its nutrients. Watering in Milorganite will ensure that the fertilizer achieves soil contact earlier and speed up the fertilizing process, but it is not necessary.

Can Milorganite be applied in the summer or during drought?

Yes. Milorganite does not contain any salts so it will not burn plant leaves during dry or hot periods.

Can Milorganite be applied to my wet lawn?

Yes. Milorganite does not contain any salts so it can be used on a wet lawn.

Is it true that Milorganite will keep deer away?

Research done at Berry College and other sources suggest Milorganite has efficacy as a deer deterrent. The makers of Milorganite do not register its product as a repellent nor actively market it as such.
back to top

Can Milorganite be used in combination with other fertilizers (and pesticides)?

Yes. Milorganite can be used as a complete lawn fertility program or with other products as part of your program. When you use Milorganite as part of an overall program, do not over-apply nitrogen fertilizer.

Does Milorganite kill weeds?

No. Milorganite is strictly a fertilizer. However, a thick lawn will choke out existing weeds and help prevent weeds from germinating seedlings.

Does Milorganite contain grass seed?

No. You can mix grass seed with Milorganite to ‘bulk up’ seed to make it easier to spread.

When can Milorganite be applied?

Milorganite can be applied any time during the growing season and it is suitable for your climate and growing conditions. It can be applied at any time of day.

What about Milorganite's phosphorus?

The slow moving phosphorus in Milorganite stays in the soil for the plants to use. University tests in the soil of Florida show that Miloganite's phosphorus is available to the plants but does not move into the groundwater.
