from 438 reviewsI had just planted Scott’s Fescue Grass Seeds (new lawn) last summer 2021 and in just 35 days ago, some areas of the lawn were turning a little yellow in color (lacking iron). I purchased Covington’s Liquid Iron Solution and applied to the lawn. It worked so fast in keeping the grass its green color. Amazed!! The combination between the Liquid Iron and Fertilizer was superb!!!
We are hooked in purchasing our lawn care products from Covington Naturals. I had gone outside just now to take photos of our lawn and a passer by had complimented on how good the grass looked! Thanks Covington!!
Oh my goodness, I am so happy with the results from using the Covington Naturals Green Grass Paint for Lawn. I was not emotionally ready for a brown lawn because of the drought. Thanks to Covington Naturals super easy application, clear directions and labeling, vibrant color, and the great price our backyard looks beautiful and alive! Thanks for a great product!
I love my new painted lawn. I painted my grass a week ago and it still looks fabulous.
Here in Central Texas, due to the intense heat during the months of June, July and August, the months of June, July and August is sometimes referred to as the “Three Sisters”. I applied Covington's Enzyme Max® - Liquid Lawn Aerator in April. I am very encouraged by the results I am experiencing thus far. Areas of my lawn that was damaged due to last year's intense summer heat is showing new growth. Additionally, currently my irrigation system is using 25% less water than it did last summer. I will give Covington's Enzyme Max® - Liquid Lawn Aerator a 2 thumbs up!

I have placed my second order round of 256 oz. of the ENZYME MAX to spread across some bare, hard red Georgia clay soil that I will soon be planting Bermuda grass. This soil is ULTRA compacted and lacking of good nutrients. IT’s a process, it will take time, and sadly it will take a few more rounds….but this stuff is working!
The aerator works great. The soil is less dense. Grass growing nice and thick.
Trying to solve my thatch problem I turned to Liquid Aerator. Early results are promising here in the Northeast. Best grass ever. True test will be in July and August. Customer service is outstanding.
Applied this product after 2 years of struggling to grow my lawn (new home). I overseeded last fall but still wasn’t happy with my spotty thin lawn. After a few waterings/rains I’ve already noticed the Kentucky blue finally starting to fill in. Read the label and understand the product will take time to work. I’m still planning on core aeration this fall with another overseeding, but I can say confidently that I can already see the difference. I’m planning on another application of liquid aeration in a few weeks.
We have a dry creek bed for downspout drainage that has steep slopes comprised of a lot of clay. After one accidentally heavy application of liquid aerator (because I had the sprayer settings wrong), we had several more downpours that usually wash away soil and mulch. It was wonderful to see that the mulch remained intact, which I hope is due to breakdown of the clay soil allowing the rain to penetrate rather than run off the surface. I am ordering more for a second application, and for our lawn.
We have mostly clay soil. It was completely compacted from years of flooded rainwater. When it rained, the entire back yard flooded and it would take days for the water to absorb. The ground was so compacted that we couldn’t even get grass to grow. We tried manual lawn aeration which did not work at all. We’ve only used the enzyme max twice, and going to use it for the third time soon. It is amazing how this simple product has improved our soil and allows the water to penetrate into the ground. Neighbors, family, and friends have all commented on our yard and they say that it “has never looked so good”. I think this product is what has made all the difference and has saved our backyard from becoming a pond. This company is also very helpful - I contacted them for help with application and how to use this product with grass seed and they personally called and emailed with all the information I could need! And the best part about all of this is - it worked!! Great company and great product.
Loved this product! Overall seen a huge difference in my tomato yield! Thank you!
Easy to apply. Great results on northern climate yard.
The lawn is healthy and lush... the best it has looked in years.. very easy to apply with the hose end sprayer
Had trouble getting grass to grow, not any more. Just remember it's only one piece of the puzzle when getting grass to grow. If you got poor soil grass will not grow.
Flowers seemed stagnant applied the growth nutrient noticed change within day or two.
