Q: Two years ago, I replaced my fescue lawn with dwarf mondo grass. I planted sprigs about four inches apart. So far, so good, except for one problem: in the bare spaces between the sprigs, there are lots of weeds growing. Can you recommend a weed killer?

A: Sethoxydim (Vantage) would be your best bet for grassy weed control. Imazaquin (Image for Nutsedge) is labeled for use on most groundcovers. Vantage is difficult to find at garden centers but Cooper Seeds (www.cooperseeds.com) in Auburn has it.
