Well, drove past the school today. Again, hardly no rain (<1/4") in the last week, even 2 weeks since I sprayed the Primo. The grass where it was trimmed down to 1/4-1/2", has all grown back to regular height. It doesn't NEED to be trimmed, but I believe that's mostly due to the fact that the whole entire property doesn't NEED to be mowed. In fact, I'm still trying to deicde if we're just going to skip it this week, since we're going to mow it tomorrow (Thursday) and then no one's around until Tuesday anyways for the 4th. Anyways, even the tree rows from the previous pics, where I went down one side, then back up the other and overlapped, that grass has grown just as tall as the other. It IS kinda spotty though, which would make me believe that the low volume of water is what causes the problems, not the Primo itself. I think the next time I test this out, I'll either use my Lesco skid sprayer, or maybe take a backpack sprayer and spray as I'm mowing / trimming?????
