| The clover-like leaves and yellow flowers would match both Oxalis and Black Medic. The maroon/purple color is a match for Black Medic. Products containing 8% Triclopyr are a solution for both Oxalis and Black Medic. A typical product for that herbicide is Weed-B-Gone Clover, Chickweed and Oxalis Killer. It works very well, but is a slower kill - typically two applications 14 days apart. Do not expect to see a quick kill like with regular WBG. WBG Max contains a small amount of Triclopyr, but it is not enough for those weeds. Get the right stuff. |

| Hi dmoore66, I'll second what Andy said. I actually started writing this before I saw his post, and just before I posted I saw he had already helped you. But anyway, this is what I had for you: Without a picture it's hard to say, but you mentioned tiny yellow flowers, and the tiniest yellow flowers I've seen on a clover-like plant are for a warm-season annual called Black Medic. If it's in my sideyard, backyard, or median strip, I usually don't pull Black Medic out because it's a nitrogen-making plant that will benefit your nearby grass. It also goes away since it's an annual. It should be disappearing really soon here this fall. It's easy to pull out without spraying. But since you mentioned you've sprayed Weed-b-Gon and the plant is still around, it's possible you have Yellow Woodsorrel and not Black Medic. It's harder to eliminate Yellow Woodsorrel (also known as oxalis). You may have to spot spray it several times, according to the Scotts Lawns book, but it's an easy weed to pull out too. I don't like yellow wood sorrel so I pull it out whenever I see it. But yellow woodsorrel isn't easy to get rid of because this particular weed has seeds that are capable of germinating throughout the growing season, according to Scotts. And I keep seeing lots of sorrel this year. After the last good rainfall we had, I saw yet another round of yellow woodsorrel sprouting. It's yellow flowers are larger than Black Medic's, which are rather inconspicuous. Scotts: "In the South, yellow wood sorrel can be perennial; in the North it does not survive harsh winters." By the way, Canadian rock legends Rush were fantastic last night in St. Louis. |

| Hi again. I see some triple heart leaves in your photo which is indicative of yellow wood sorrel, but without a more close-up photo, I won't say for sure. It looks like you have some prostrate spurge in the upper left underneath the rock. Without a closeup, it appears you might also have some kind of third plant or weed in there with a reddish tint, but viewing from afar with slight bluriness is always problematic. |
