Vinegar weed is trichostema lanceolatum and you can look that up in wikipedia. It has blue flowers. I've never heard of fatweed, though there is a weed called fat hen, which is different from vinegar weed. I should have thought that raking your lawn regularly would pull out seedlings and that using a product like Weed and Feed would help a lot. You probably know this already and I'm wondering what it is about the weed that makes it a particular problem?
