I had a soil test
"I had a soil test done. Put down lime, and a medium rate of both the humic dg and the bio char. Lawn doesn’t look any different than the neighbors yard who doesn’t do anything but mow his grass. It definitely does not look like the one month change in the YouTube video of the yard makeover. I have no proof that it works but I do not see any negative effects in the yard. I will be using the Surge weed and feed as soon as the temperatures are right."
