Ortho no longer makes this for some reason so I bought 3 bottles. Regular Ortho Weed B Gon hardly does anything. This stuff seems to work but take several applications over a long period. My weed problem mostly consists of Hairy Bittercress and Chick Weed.
This product works on some weeds, not on others. At least it did not harm my St Augustine grass. I will have to spray again to see if a second application works better
