Just bought this home in July of 2017 and it was filled with clovers and weeds. Sprayed roundup [CORRECTION Weed B Gon] in August. And sprayed prodamine in September, thanks to the genius men in the forum . I also sprayed prodamine again a few weeks ago because I thought we were warming up (should have known better). Here's where I'm at now:









I have no need for a green lawn year round so I want to get rid of what I assume is POA/Winter Rye and Purple deadnettle.

Any ideas on my next course of action?

Sprayed roundup in August.

Did you spray round up's white and green bottles, like this? https://www.roundup.com/en-us/products/lawn-weeds
or did you spray glyphosate?

I also sprayed prodamine again a few weeks ago because I thought we were warming up (should have known better).

You applied prodiamine at an okay time so don't sweat that.

Looking at your photos from top to bottom
1. You've got a solid amount of Bermuda that will fill in once the weeds are gone.
2. I can't tell what exactly it is on my phone but it doesn't look like poa annua; I think it's annual rye grass.
3. Purple deadnettle - smoke it with a standard three way like ortho weed-b-gon, Trimec, etc.
4. The bottom looks like wild garlic or wild onion. You can do multiple applications of a three way, but it will likely take a year or so to get rid of it. You can use imazaquin (Image) or metsulfuron (MSM Turf or Manor)

Off the top of my head, I'm not sure if there's one product that would control everything.
Metsulfuron, which would take care of the wild onion/garlic (if that's what it is).
Celsius will get wild onion/wild garlic (probably multiple apps), maybe the poa annua, and unsure on purple deadnettle or rye grass since neither are on the list of controlled weeds but it might do damage to those weeds.
Three way would get the purple deadnettle for sure
Monument would get the poa for sure, wild garlic, and unsure on the rest.

The cheapest option in my mind would be spray with a three way and hand brush everything left with glyphosate, and you'd probably be left with wild garlic/wild onion, which you could treat over time.

You could also do a broadcast spray of Celsius and hand brush whatever is left with glyphosate.

I'm curious to see the other recommendations. Anyone know if a blanket app of MSM would get rid of everything but the poa?

Here's my thoughts.

I don't think that's annual ryegrass. Look more like volunteer fescue. Not that it really matters but that isn't purple deadnettle it's Henbit. To help increase the effectiveness of herbicides on wild onion/ garlic it's advised to mow them or cut them before apply the product of your choice.

I have since replacing my normal three-way products to Battleship III or something similar that contains Triclopyr. I get faster and more complete control of winter broadleaf weeds with this type of product. It also works great on Wild onion and garlic.

To summarize

Winter broadleaf post-emergent control:

Cheap three-way products work but may take multiple applications. What I call "spiked" three-way products that contain Triclopyr work very well. MSM is another good option. In a lot of new lawns with heavy winter weed infestations get hit with a tank mix of either a cheap three-way and MSM or a "spiked" three-way containing Triclopyr.

Winter grassy weed post-emergent control:
If heavily infested I blanket spray Revolver otherwise I spot treat with Katana.

Sorry, I've got my toddler with me today so I'm going bonkers. I meant to say Weed B Gon like this https://www.ortho.com/en-us/products/weed-control/ortho-weed-b-gon-weed-killer-lawns-concentrate2

Thanks! Would you do this now before green up or hold off? I'm following an Alabama Extension document I found but it mentions nothing about winter grass post-emergent control.

There's lots of information out there.

My goodness Movingshrub! I went through UT, Alabama, Arkansas and they just aren't like the NC and Clemson sites. At least not to me. Thanks man, this is solid. Felt kinda bad for asking such a basic question but thanks!!! Literally the answers I'm looking for :thumbup:

It's easy for their to be information overload. This is just the tip of the iceburg depending on what you're wanting to learn.

I went to UT and Clemson, and I live in Alabama. Auburn has some nice maintenance calendar and starter info.

UT has the mobile weed manual which is pretty useful but I'd suggest double checking the label to confirm.
http://www.mobileweedmanual.com/search-weed.aspx

Clemson has the Pest Control Guidelines for Professional Turfgrass Managers which was kind of my starting read for what herbicides do what.

Clemson also have a bunch on their extension site
https://www.clemson.edu/extension/hgic/

UT has an extension listing of publications too but I am being lazy and don't want to find the URL.

UGA has a lot of information out there as well.

Thanks for the wealth of info again Movingshrub. This is enough to set me up for a season or two without questions. Hopefully, :lol: But seriously good stuff!
