My yard has become somewhat infested with these weeds. Trimec Classic at 1.5oz/gal seems to damage them, but not kill them. Much of my yard is tiffway 419 bermuda, with some remaining fescue, so the kinds of chemicals I can use seems a bit limited. I'm in the north-central area of North Carolina.

If anyone can tell me what these are, and what chemical, or blend of chemicals, will kill them and not harm the bermuda, it would be greatly appreciated...

  • If it was my lawn, I would be doing some digging in the area with the most weeds. Depending on the size of the lawn, of course. Chop up the weeds, add some grass seed, water, mow, lather-rinse-repeat.

  • I didn't plant violets and they've sprouted up in a few places. Weed or not, shouldn't trimec classic kill them? And if not, any idea what would (and not the grass)? Thank you

  • @BobaFit It's almost an acre of grass with the weeds scattered all throughout. The weeds don't own the yard, but they have popped up all over so I'm trying to find the right chemical/mixture that can remove them. I thought trimec classic would be it, but apparently not.

  • Different herbicides work differently. Some only kill certain plants, and some only during certain growth phases. Read those labels carefully!

First weed is probably something endemic to your area, second weed is what we in Wisconsin call "burnweed" (a rayless composite with an ugly flower that sets air-borne seeds), and the third is, as noted in the comments, a violet. Let the burnweed get tall, then hand pull it. It's an annual so if you don't let it go to seed and have neighbors upwind who don't have it, then it'll be gone next yeear. You'll have to hand-dig the violets; I recommend a Japanese garden knife (AKA a hori-hori) because the point allows you to pierce the lawn without damaging it.
