I have to put in a bid for a commercial lot that has monkey grass surrounding the landscaping. The job is fairly simple in terms of getting the job done. But, my stepfather has monkey grass and I find it hard to trim. I tried weedeating it but it seems to just blow with the weedeater. In this commercial lot, the monkey grass is thick and looks fairly good right now, except it has some tall single weeds sticking up within it. My question is, is there a proper way of trimming or cutting the monkey grass so it don't get outta control? Do I have to hand pick the tall weeds outts the middle of it?
