Answer: The safest approach is to dig the plants out, then eradicate the grassy weeds, roots and all. When the planting bed is clean, replant the plants. If that isn't an option, hand dig the weeds and then, to keep grass and other weed seeds from germinating, cover the bare soil with several inches of organic mulch or use a weed barrier (or several thicknesses of newspaper) and cover it with a decorative mulch of bark chips or rocks. While this approach is labor intensive, you'll be rewarded with healthy plants and a weed free garden bed. Enjoy your garden!
