Hey steve,<p>sounds like you have used bio's before. Is what I am trying to do sound like a good idea or should I just think about something else. I figured it was worth the 50 bucks to at least try it. The grass is growing along the stretch I want to treat, but not very well. I want to get it up to par before I get a lot of weeds (and also I have people asking, "everything else grew nice, but why is that one spot........?" <p>The sales rep saw the spot and said it was a perfect situation for it. Now, I don't believe everything the sales rep says, but it sounds like a good idea in theory. <p>I just don't want to stimulate weed growth instead of grass growth, or worse, stimulate no growth.<p>I will have to investigate prices later on. I'm new to this, so I just wanted to test the waters. If I like it, I will have to try<br>the bolster, if it is that much cheaper.<p>Also, the sales rep did say that I should apply at about a half rate. He said the same thing you said, now that i remember. Just skipped my mind I guess. My memory isn't so good, thats why I write everything down. <p>Also, what kind of rates for new lawn installs. He said full for new, and about half for rennovations. (I'm getting my mind back now). Does this sound about right. Now its hard because its a diff't product, but just asking.<p>steveair<p>
