I planted Greenview Kentucky Blue grass mix (3 kinds of KBG in the bag) at a client's yard where she had a tree and two flowerbeds with WHITE STONES (marble chips over fabric). She calls me and tells me that she has crab grass all over the patch where the marble chips were. I told her, "no, that's just grass starting to grow". well, i went there and sure enough.....there is the actual thin shoots of grass, but there is this TALL, LIGHT green, weird looking grass, that's not really grass. can anyone tell me what this is? I have never seen this. The other area where the tree was seems to be ok. but where the marble chips were, there is this thing overtaking the grass. i have included a few pics to help identify it. please help. there seem to be a few more patches close to the ex-landscape beds that i did not even touch. could it be something in the fabric? the marble chips?
