(Reposted from Watercooler) A couple months ago, my husband and I jumped on the PIE bandwagon. But I swear, our grass is looking spottier and weedier than ever. Sometimes the guys come while it's raining to spray. I know they are a popular choice around Central Park, and I've seen some good-looking lawns with the alien sign. For anyone who uses PIE, do you supplement with your own treatments?
