I bought this product in the spring (May). I was trying to revitalize my lawn after letting my yard go by not fertilizing for a year. Weeds and crabgrass were starting to take over. Anyway, I discovered this product on the Medina website. I was eager and excited about using it. So I discovered it being sold on Amazon website and started to read the reviews (only 2 at that time). One of the reviews gave it one star (P. Burnside) saying that the product was "worthless". However, knowing that many a people swear that Medina makes great products (ex.: Hasta Gro), I dismissed that review.
Upon receiving the product, it came well packed and I was expecting some great results. However, after applying (May 15) and waiting about a week, I was concerned because I hadn't seen any noticeable results yet in color or growth. And considering it was a liquid fertilizer I felt it more ample enough time to have seen some progress.
So it is now fall and I was actually going to try the Medina product again thinking that maybe I had let the lawn go for too long and that it was going to take more than one application before I would notice any real results. However, I had procrastinated ordering the product and I wanted to immediately put down an application. So I went to Walmart and instead of buying a liquid fertilizer I decided to go with Scott's Winterguard granules. I applied the fertilizer (September 26) and within a week I started noticing that the grass was growing and looked as if it was standing at attention. Within 10 days the grass actually looked "fuller and greener" and my neighbor even asked me "did you fertilize?".
What I am saying is that the great results the Scott's Winterguard yielded inspired me to leave this post about just how little (if any) results the Medina Hasta Gro Lawn Fertilizer produced. There was absolutely no color change and it did not accelerate the growth. I was highly disappointed with the product and I would discourage anyone from buying and using it. I agree with the aforementioned review that this product is worthless, at least it was for me. I said it did nothing for my lawn, well, it actually made it worse since it did nothing. I won't be buying Medina again.
