Customer Questions & Answers

I have heard that deer will not bother a garden when milorganite fertilizer is used, Any feedback on that?

Asked by: Eddie
it is not 100% but I notice the deer are not as interested and the rabbits are gone!

What does this do to weeds?

We have a lot of patchy grass/weeds in the back yard because the previous owner had dogs that made bare spots in the grass - perfect places for weeds! Will this product make the weeds grow stronger as well as grass?
Asked by: 2sweet4most
Cut your grass low (2.5 inch) 1 week to 10 days before using this product and use a backpack Spayer and spray your weeds with Ortho Weed be gone or Spectracide Weed killer. Then after that 10 days use the Milorganite. Have done this many years and love what it does to my lawn. No more Scotts Hi priced stuff for me.. Occasionally I will use the Lesco 0-0-7 Pre emergent in Late Feb early March for the wild grass but other then that I stick with the Milorganite

I think I may have over applied as my grass appears to have burnt, is there a way to undo this?

Asked by: shoeless
The label states that this product will not burn, and I have not had any problems with it.

Can I throw down seed any time after Milorganite is down?

Asked by: JerseyBoy
Sure, why not? It doesn't contain a preemergent or other weed killer and plays well with all kinds of plants.

Customer Reviews

36 lb. Organic Nitrogen Fertilizer is rated 4.6 out of 5 by 361.
Rated 3 out of 5 by from Be Careful to Watch Spreader Settings. I think that I am going to like this product but I find the instructions listed on the bag to be incorrect to what I read. I have a Scotts Pro broadcast spreader with edge guard, and the way I read the chart the setting should be 11-1/2. This setting is not correct for this spreader. It allows about 2 times more product to be dispensed. I am not complete with my project yet and have about 1/2 of my yard left to complete so I will try a different setting. Everyone needs to really check out their spreader and be prepared to adjust it according for the use if indeed the bag is correct for the square footage it should cover. I certainly do not think that I have harmed my lawn by putting out the first bag to only cover about 1200 square feet (should have covered about 2600 square feet), but it did take me a bag to realize that too much was being consumed. Just be aware that the instruction may need some tweaking.

Rated 2 out of 5 by from Might work but it smells bad Applied a whole bag of Milorganite to my shrubs, trees, and plants last week as the reviews I read were all good. Have watered several times, but the smell continues to be very bad. Both my next door neighbors asked what died in my yard, and they aren't the only ones to inquire. Neighbors dogs and cats have taken a real liking to my yard and continue to come over to roll in the fertilizer. You can only guess what happens when they go home. Guess time will tell if this will green up and grow my landscaping materials. I'm going back to using something more expensive and much less offensive to the nose. Whew from Annapolis, MD.

Rated 4 out of 5 by from Easy greening I like this product because it greens your lawn without causing rapid growth, who likes mowing more than you have to! I will tell you you don't have to water it in, but when it rains there is a slight temporary odor.

Rated 5 out of 5 by from Milorganite....Not just for Grass Anymore! I purchased this specifically for the new raised garden beds that I built over the winter. I panted them with Corn, carrots, radishes, lettuces, snap peas, bush beans, tomato varieties, broccoli, cauliflower, cabbage, green peppers, atris peppers and marigolds (for bug and pest control) I have never had a garden that has produced as well or as much as this one is going to produce before the end of the season....The Milorganite made my new beds EXPLODE. I am attaching photos that were taken on May 26th, 2016......WOW!

I just switched over to Milorganite this year and I am happy with the results. No more worries about watering in synthetic fertilizer. I like the slow and steady results from Milorganite. The lawn seems healthier and the iron in the Milorganite helps with a nice dark green color. I would highly reccomend this product.

Rated 1 out of 5 by from Sorry, does not work. I live in north Texas. I bought this item twice at Home Depot. Sorry to say I got zero results and ended up buying regular fertilizer due to lack of greening and growth. Yes, I just had to try it again after no results the first time. I guess the hotter summers here just are not right for this product.

I have tried to grow grass behind my house several times for the past two years only to end up disappointed with only a few patchy stubs.  This year I decided to give Milorganite a try after reading numerous reviews. It worked! Milorganite is now my fertilizer of choice for my entire lawn.
