re: Can I get advice/tips for my lawn after the winter? ::Updated with pics:::

The grass remaining in the spot where it’s somewhat brown

Here's a picture of some of the grass that's in that big brown dead area.

There is some other very small circles throughout the yard, but they are hardly noticeable. The picture of the entire area is up a few post.

Is this just burn from the MSM? If yes, does that mean I sprayed too much chemical? How long before my yard goes back to being green?

This stuff is getting annoying. It seems like as soon as I fix one problem, two more pop up.

Yup. That is what it is. Propiconizole or Azoxystrobin will knock it out. I would propiconizole though and save Azoxystrobin for Take all patch.

Your story is my story exactly. Did all the same things and had the best lawn ever for abt 2-3 wks. Now gray leaf spot too. I’ve become exhausted dealing with the constant problems and I’ve had them ALL. Having trouble deciding whether to keep at it or bail and look forward to hunting season.

I think I'm ready to tackle my Dallis grass issue. My squares I laid have come in nicely, I fixed that fungus patch that was there. Now it's mainly just the few spots of Dallis grass that are annoying me.

It was previously discussed a little before, but just wanted to check in to make sure how to handle it.

I have a little round up left, so should I spray those spots?

After spraying, should I dig up those areas? If yes, how long after spraying should I dig it? If no, after the Dallis grass patches die, should I cover with sand?

That sounds like a reasonable plan. Since Dallisgrass largely spreads by underground rhizomes I’d want spray and kill it before digging it up and filling the void with sand. Technically you don’t have to remove the dead weeds but I think St Augustine from the surrounding area would fill in the void spots more quickly if you did so. I would think in this heat, you would see dead Dallisgrass in 2-3 weeks post spraying.

I’ve been lucky enough to personally not have to deal with dallisgrass, but other posters have, so hopefully they will chime with their opinions/experience/recommendations.

Once it browns, I should be good to dig it up?

---

Yes.

Also, while I'm thinking about it. On my mapped out schedule a few pages back I have around Oct for preemerg, then nothing until the clegs spray in Feb. If there are some winter weeds that get through, I can spray the clegs at any point during the winter months right? Or will it be too cold for anything to be useful during those months?

I’m sure one or more us will post a reminder on timing of fall application of pre-emergent herbicide, for southern LA, mid-Sept/mid-Oct. I usually contact Dr. Ron Strahan, the weed specialist with the LSU AgCenter in early Sept, to confirm his recommendation on when to apply, and pass that on.

You can spray weeds that escape pre-emergent herbicide during the winter. The Cleggs winter weed cocktail (weed free zone + atrazine), MSM Turf or Celsius, Atrazine or Simazine, will most likely be your herbicides of choice. Remember, the sooner you can spot them, and younger they are, the easier they are to kill. For southern Louisiana, not to many days it’s too cold in winter not to spray weeds, but certainly “winter” days when afternoon temperatures are are the warm side, say in the 60s/70s are more conducive to spraying and herbicide translocation by the weeds.

Is Dallis grass indestructible?

some people would say so.

I sprayed round up a few days ago. The little st Aug I hit has turned brown. The Dallis grass is standing tall, strong, and green as hell. Just standing out brighter and taller than the rest of the lawn.

It’s going to take more than a few days. Give it two weeks - maybe a little longer. It’s ok to spray it again after after 2 or 3 weeks if necessary. Dallisgrass is tough. Might very well take a couple of applications.

Without rereading the whole thread is it bermuda or zoysia?

No other way around it. Msma will do the same as glyphosate. Unfortunately you have a tough road to hoe. The only other option is to use Celsius (at the high rate) and sedgehammer every two weeks. Your lawn or the dallisgrass cannot be under any additional stress. Correct mow height, correct amount of water, no heat stress. There is a chance that your St Aug will overcome the dallisgrass.
