Hi Carl,

It will be very difficult to kill crabgrass now. When the plants are full grown they're resistant to herbicides, and using something like glyphosate (commonly sold as Roundup) will kill other desirable plants around the crabgrass. If you choose to try this read the label and apply it very carefully.

At this time of summer the best thing to do is to dig the plants out. Next year, use a pre-emergent in May that will prevent crabgrass seeds from germinating. The plant is an annual so what you see now won't come back, but will spread many seeds this summer.

Creeping charlie is another very tough weed. Fall is a good time to kill it. This page has information:

Good luck.
