I could tell a difference the next day easily. My Tall fescue looked healthy. I bought Turf Grass Pro Micros because I wanted to help my grass fight off fungus. I took soil samples from my yard and noticed it lacking the micro nutrients that TurfGrassPro Micros will add. I sprayed the front yard only and noticed the back yard still developed fungus. This does not get rid of fungus it helps your grass fight it off! I will still use fungicides. I used 3 ounces in 4 gallons of water in a battery powered Chapin sprayer. I will try to spray my front and backyard every week when weather permits. and retest my soil in the spring.
My tall fescue obviously loved this. I applied this out of a hose end sprayer with fulvic and humic acid at a rate of about 8oz. per 1,000. The richness of color and shine just might make a neighbor or two jealous.
I used this last year and could really tell a difference. My soil test from early on in the year said I was lacking micros. Just sent off my soil test from this year and looking forward to seeing how much things have changed. Great product!
