Q.is there a selective herbicide that will protect Herniaria Glabra from yellow oxalis and other weeds?
We have spent a year replacing our grass lawn with Herniaria Glabra (Dwarf Rupturewort – Green Carpet) in our backyard. Yellow oxalis is taking it over. There are other weeds, but the oxalis is the worst. Is there a selective herbicide that we can spray on the Herniaria Glabra lawn to remove yellow oxalis and other weeds? It’s almost impossible to pull out yellow oxalis without also removing the Herniaria Glabra
Thank You

Oh boy... This is an aggressive one. You will have to choose any herbicide that is selective for oxalis. They will all be labeled as such, and can be found with a google search. Now, you may want to treat very light at first to make sure that it only affects the target plant, but these herbicides are pretty spot on with correct treatment use.
