Tania from San Mateo, Ca writes

New sod dwarf fescue +kentucky blue grass approx 4 weeks ago, will W4 treat poa bluegrass+oxalis?

I place new sod (dwarf fescue and kentucky blue grass) about 4 weeks ago. Now there is oxalis weed and poa bluegrass weed. Does Q4 treat it as spot treatment during the winter? How soon can I treat my sod with weed killer?

Answer:

Q4 Plus Turf Herbicide can be applied 3 to 4 weeks after sodding new grasses so it should be safe for you to apply it now to treat/control oxalis. Q4 Plus is not labeled to kill poa annua, since it's also a cool season grass, you can only spot treat with a non-selective like Roundup to get rid of it.
