Answer: It sounds like filaree, sometimes called wild geranium, but I can't tell without looking at it. Why not dig one out, roots and all, and take it to your local cooperative extension office, Master Gardener Clinic, or well staffed nursery for positive identification? Once you know what you're dealing with, helpful folks at one of the above locations can suggest control measures. You'll want to feed your lawn next month (September) when the weather is a little cooler.
