Petramax Liquid Nitrogen Fertilizer 28-0-0 NPK - 32 Oz Spring & Summer Liquid Grass Fertilizer for Lawn, Spray on Easy to Apply for Deep Green Lawn Care - Slow Release High Nitrogen Turf Builder

Product does work. I have bought this multiple times and it does make the lawn greener. I use a Petramax battery operated sprayer https://a.co/d/052UAaCL to spray the fertilizer on the lawn.

This stuff is the bomb. I used in a pump up sprayer.

Surprised at the small quantity. It is also expensive. But don't be fooled by either. This works really well. A single application made my lawn looking from dismal to good. A second application made it very good. What's the point in buying large quantity of something that's cheap but works mediocre at best? I would buy this again next season.

This stuff works great and my lawn has never been so green. I am proud of the way my lawn looks compared to my neighbors. Thank you Christina for your help in suggesting I try this product. I am now a repeat customer!!

I have read the reviews and noticed a lot of the reviews worked at the manufacturer of this product, but I was willing to give it a shot. Yes, $50 isn’t cheap but it was cheaper than refilling this specific area with mulch after every rain. I put about 2/3 of the gallon into an area that was a triangle, approximate dimensions are 20x12x13. The mulch was about 4-6” deep throughout this area. The problem with this area is when we get heavy rains, our gutters overflow into this area and washes the mulch out. We just had a tropic storm yesterday here in North Carolina and got about 7” of rain. No mulch washed out from this area. The huge issue with this area besides the overflow from the gutter is that the grade goes down about 1 1/2 feet in from the highest point to the lowest. After the rain from yesterday, there was some packing of the mulch just under the gutter but none of the mulch shifted or washed out. I will purchase a second gallon to reinforce what is there because of the amount of rain probably weakened it a little. Very happy with the product. Just an FYI, the mulch used was that cheap mulch you get from the gas station, 10/$10 with inconsistent sized pieces.

Did not see very much difference.

Look if you're using iron but you're not using nitrogen you're kinda wasting your time. It's gotta be both. This stuff worked great for me. A noticable difference just with the first 24 hours (which means I definitely had a nitrogen deficiency). If you apply it but don't water the daylights out of the lawn for the first week you're not going to see growth or color improvement. Water grows grass better than anything. You can't just spray nitrogen on the lawn then water for 15 minutes every other day and expect growth. You can't just put down nitrogen and never put iron and expect a huge improvement. In the high desert of Colorado if you're watering for less than 30 minutes daily you're really just wasting water because the water you are applying never makes it to the roots and just cooks off. Big drinks less often are better than tiny drinks more frequently. If you're going to water every other day or every two days it's gotta be 30-60 minutes, or more specifically 3/4"-1" of rainfall per week. Anything less and you're just "keeping it alive", you're not gaining ground. If you use this product as directed and a healthy water regimen you will absolutely notice a difference. Grass is very difficult to grow here and this product will absolutely become a regular application for me.

It has no smell at all. It was very easy to use following the directions and on the back. I used a tank sprayer to apply mine. I would definitely buy it again. It greened my lawn within one week’s timeframe. Just FYI.. I’m a first time homeowner and single woman who’s still learning how to take care and manage my lawn. I mow, weed eat and garden on my own. Everyone that passes my house has given me so many compliments. Please buy this product and follow the directions as required. If needed, you can test your soil to make sure you need more nitrogen.. I needed nitrogen and iron.. so I purchased this one for nitrogen and ironite for the iron deficiency. I’ve added some before and after photos as well.

The bottle is smaller than I imagined and I was skeptical that it would be enough for my lawn. I probably diluted it more than recommended but it was very effective at darkening my lawn. In fact, there were a couple of strips of grass where I missed and the contrast in color is very noticeable. Not cheap but it is effective.

Great stuff results start to show at least after 6-7 days

It worked out well for my purposes. The only issue I have is that it doesn't provide clear mixing instructions or a dilution rate. So, I went with a 4.5-to-1 mixing ratio that Google suggested.

It made my Lawn really green!! Pretty pricy for a medium bottle but it sure does its job!

It helped the grass to grow much better.
