Yes you should either spray them with a weed killer or simply use a shovel and dig up the sod layer, that is what I do each time I expand my flower beds. No more weeks. You can also use a recycled rubber mulch which lasts for 10 years, cuts way down on the mulch work.

How do you kill grass growing with your phlox?

there are weedkillers that can selectivly kill grass, ask in a gardening store. Weed killers are toxic to you and the environment. Get as much grass out by the roots as you can and mulch like crazy under the phlox. Weed cloth can be purchased in the same store as the weed killer, so can the mulch. Lay down the cloth in early morning or evening and cut slits for the phlox. Gently pull the phlox through the slits, and flatten the cloth as if you were making a bed full of flowers. Mulch over the top of the cloth. Try not to get too much cloth or mulch around the stems of the phlox, that can create several negative situations. The benefit of this over weed killing chemicals is that it's more effective, retains moisture, it isn't toxic to you or any other critters. If you ever decide to grow more phlox or mingle other flowers, push aside some mulch and punch a hole in the cloth.
