Common Lespedeza in yard

I second the MSM

Thanks for the tip.
Took an additional walk around and noticed some stiltgrass too.

Just bought some Celsius. How does it take to show results? I'm trying to control buttonweed, Netsedge, and carpet grass mostly.

You’ll see results pretty quickly on V Buttonweed and carpetgrass with Celsius, particularly in this heat, within a few days to a week. Make sure you use surfactant (spreader sticker) in the spray solution.

You’ll need a different herbicide to control nutsedge, I use Sedgehammer (halsulfuron) but I have also used “Image Kills Nutsedge” in the past and i was pleased with the results.

Surprising, the Celsius is turning the nutsedge yellow first.

I know yellow and purple nutsedge are not listed on the Celsius label for control, but that doesn’t mean it might not cause some damage. Now, Celsius does effectively control Green Kyllinga which is a sedge, like “miniature” nutsedge. Control of green kyillinga, carpetweed and doveweed is the main reason I use Celsius, those weeds aren’t effectively controlled by MSM Turf. Otherwise I usually use MSM Turf, to control most other broadleaf weeds b/c i find it equally effective and it’s considerably cheaper.

I know I do see quicker results when using Celsius, usually within days, compared to MSM Turf but they are both very effective herbicides.

Make sure you are using the right concentration of Celsius as stated on the label for the weeds you are trying to control and mix a surfactant (spreader/sticker) in the solution - the surfactant is important.

buttonweed starting to wilt hard. have not seen much results out of the carpet grass, which is what I need it more for.

Thanks.

funny thing. It absolutely merkin' the crabgrass

I'm not sure.. This is my first time using it.

Ive spot sprayed in the past and frequently throughout the summer with Ortho Weed Be Gone Would Celsius be more effective and prevent the need to spray throughout the summer?

---

Celsius is a post-emergent herbicide so it’s not going to prevent weeds. Depending on what types of weeds you are trying to control, consider using a pre-emergent herbicide in late winter/early spring and fall, it won’t eliminate weeds but certainly helps control annual weeds and reduces, not eliminates, the need for spraying.

I use dimension every spring and fall with atrazine before the spring run

That’s what I use, both late winter and fall, plus some simazine in the fall. I’m thinking of trying a late spring application of Barricade pre-emergent to help control doveweed, which is becoming an increasing problem in my yard, and which Dimension does not control. Not used Tenacity but does seem to have both good pre-emergent and post-emergent control of a number weeds, but not the 2 I’m having the biggest issue with - doveweed and to a lesser extent nutsedge.
