John from Frontenac, Ks writes,
I have dallas grass, crab grass and water grass.
Is there anything that will kill these without killing my fescue?
Unfortunately there is nothing that is labeled to selectively kill dallas grass, and not your fescue. So for the Dallas grass you would spot treat it with a glyphosate product, which would kill the Dallas grass and also a little bit of the surrounding fescue grass.Then re-seed with fescue in those areas where the surrounding fescue was killed. For your crabgrass you can use Drive XLR8, which may also take care of the water grass.
