Here is what John said in an email sent back to us at SumaGreen.
......our results are undeniable. We had bought a house that had an inground pool. The pool had been removed and the fill had sunk in around the center of the yard. We contracted a company to drop 18 truckloads of clean topsoil and level the back yard. It turns out that that finely sifted topsoil was crushed clay! The following spring we could not get grass started well in the yard even with meticulous care. We had gotten some grass to grow but it was really fighting to drop roots through the soil that you couldn't hammer a nail into. It was very patchy to say the least. We met reps from BioSoil (SumaGrow) at a PSE&G GreenFest (exact name of event escapes me). I have been following SumaGreen for years and now that I could purchase your product, I gave it a try. Within 3 weeks the results with SumaGreen Turf were noticeable by everyone. Now it is 5 weeks and the lawn is very green and healthy looking. The best part is that there are no longer any patches. We did plant seed again, but we did that last year in the spring and fall with barely any results. The fact that we have a lawn that looks above average is quite amazing considering that the alternative would have cost over $10k for new topsoil and sod (or topsoil and a lot of work trying to get seed to cover). I tell everyone about your product. It is less expensive than using standard fertilizer. You don't have to worry about burning your lawn. No special tools required. And the fact that there is no fertilizer to wash off and kill fish in our river, bay, and oceans. All positives and no negatives. Thanks for developing this product. We can do something good for the environment without compromising on performance nor paying through the nose!
Look at the Tall Fescue Grass. You can not even see where the pool was taken out!
Here is nice Bermuda grass from Texas taken by Bob Short's Lawn America, Texas where they have been making the switch from Fertilizers to SumaGreen Turf. The difference is hard to see until you get to the cost savings and what kind of money his business will save by making this change.
