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

Brother-in-law recommended to me, added it to my lawn and all, unfortunately, I have three different types of grass, however, they all exaggerated, nice green coloring.

Works great

Easy to mix in my 30 gallon sprayer. Lawn greened up quickly. Will use it again.

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.

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.

Did not see very much difference.

Great price and good product

Exactly what I wanted to help green up my lawn and very easy to apply, with a great value as well

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.

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.

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.
