Patch Perfect

It is a pian in the ass to get grass to grown in our yard. Whenever we are able to get the grass seed to sprout we rejoice. But the celebrating doesn’t last long cause with in a few weeks the dark green grass dies off. No matter what we try. We have put mulch and miracle grow on it. We have bought those grass food bottles that you hook up to your water hose and water the lawn with it, we have even borrowed a rototiller and used it all over our front yard and still nothing. So when I seen the commercial for the Patch Perfect I got excited. This grass seed is suppose to be able to grow anywhere even on concrete with out any dirt! But I do not want to pay $20 plus shipping for something that might just be shit. Have any of you tried Patch Perfect? Is so did it work for you?
