I agree with this. Haven't been thru the whole thread but I will say this about MSM

MSM is a great product as far as being very affordable and killing a broad spectrum of weeds. That being said I dont use it often as it can be very harsh on centipede and St Augustine, especially when it's hot.

IMO avoid MSM when it's very hot and during green up on those 2 grass types. It can really stunt growth.

I thought MSM was used when it got hot, and wouldn't work when it's cooler? Also thought it didn't harm St. Aug grass.


Also thought that the weed cocktail I was using WOULD damage the St. Aug grass, if used when it was too hot.

I don't treat St. Augustine much, but I use a lot of MSM on Centipede. When I use it in the heat of summer trying to kill bahia/highway grass it can definitely stunt/yellow the grass. It almost seems to make the grass just sit there. Not bad enough where I won't use it, but I feel more comfortable using a few other products if I don't need the MSM.

Not many herbicides work great in the cool. They will still usually get the job done, but will take longer and possibly need a repeat application.

carfentrazone (quicksilver) Is a broad leaf herbicide that temperature doesn't have an effect on.

Not trying to scare anyone off of MSM, I just think it is kind of harsh on the grass, especially centipede, in extreme heat and mainly during the spring green up transition.

Knock yourself out on Bermuda. Careful on Zoysia.

Just to expound a bit more the good answers you've already received on this, its not likely you be hitting max temps in in the mid- to high 80s in Lafayette until late April/May so using the Atrazine+Weed Free Zone cocktail will be fine until then, at which point you can move to MSM Turf if required.

It's not that you can't use MSM Turf at cooler temperature, you can, but "winter weed cocktail" is pretty effective, cheap per application and you are using some different herbicide chemistry to kill weeds which is a good thing, to mitigate herbicide weed resistance, which is a real thing can potentially occur using the same herbicide 12 months per year.

As gamescocks22 mentioned, that hasn't been previously addressed, during the period your lawn grass, St. Augustine in your case, begins greening up, this is a particularly sensitive time for the lawn grass and really no post-emergent herbicide should be applied at that time. That is only about a 2 week window for us in southern LA. That should be in mid-March or so for you. I think after you have cut your lawn grass twice, you should be through the "greening up" phase.

It’s important to note lawn grasses are not "immune" to the effects these herbicides, they are "tolerant", but if a herbicide is applied when the lawn grass is in stress, developing a new root system, drought, etc. some of these herbicides recommended can cause some lawn/turf damage to the desirable grasses - this will be stated on the herbicide label. Very common to see some slight yellowing of desirable lawn grass following post-emergent herbicide treatment, particularly in the hotter weather of summer, but the lawn will quickly recover if in good health (that is where mowing/lawn fertilization, etc. are important).

Ok. So going off my updated calendar on page 3, you are saying I should:

- keep my post emerg winter cocktail spray next weekend (which would be right at the end of Feb/ beginning of March).

- hold off on the MSM in March, unless it gets really hot towards the end.

- Fertilize in April.

- use MSM as a post emerg to try to kill some weeds at the end of April/May when it's really warmed up and my grass has been cut twice?

Then continue on with the rest of the schedule.

Am I following this correctly? Sorry if I'm a pain. I'm just really interested in, and enjoying, trying to get my yard right.

Yes to all, but feel to jump jump back in this thread you started at any point if you have additional questions or see some weeds not being controlled by these herbicides. I may have mentioned earlier you may some weeds that show up in the lawn in the heat of summer, nutsedge comes to mind, that might require a different herbicide all together to kill.

Oh don't worry. This thread will be bookmarked to use as my crutch. I'll keep it updated with pics as I go, so all those that have helped can see the progress.

Read many threads and not sure about when to mow during Cleggs treatment.
Weeds are getting tall rafter application or before what are suggestions for mowing this time of year.

After talking with my local nursery, they recommend mowing first before applying pre emergents. For post emergents, they said it’s ok to mow first. But to wait a few days after mowing before applying. And another few days after applying before mowing again.

ETA: autocorrect really butchered that.

Judging from the picture you posted and unless your yard rebounds nicely you are likely to have some bald spots come fall. If you don't mind cutting grass 12 months out of the year you may want to consider over seeding come fall with an annual ryegrass. It sure makes for a pretty yard.

I've been where you are and I just about have mine under control, it takes years. Because of the kids and the dogs I started over seeding in the fall with rye grass to keep them from tracking mud in during the winter. I make it a yearly practice now but my turf grass has gotten thick enough that the rye doesn't come up so thick.

You have to time you rye planting to the application of your pre emergent or it will not come up at all.

This was supposed to be my weekend to put the Cleggs cocktail down again, but I was locked up with a crappy virus. What is the strategy when dealing with rain with the spray? I know it's supposed to rain some this week, so I didn't want to put it down at a bad time.

This is from the Weed Free Zone label “ Do not apply this product immediately before rainfall or irrigation. Rain or watering within 4 hours after treatment may reduce effectiveness“.

From the Atrazine label “Rain or water within 2 or 3 days of application may decrease the effectiveness on emerged weeds. However, for the control of weeds from seeds, rainfall or watering is necessary within 7 to 10 days after treatment.”

Bottom line, if you can wait to apply where you won’t have rain for a couple days that would be ideal.

Is the weather too cool now to spray the Cleggs post emerg spray? I was supposed to do it last weekend, but rain screwed that up. I was planning on knocking it out tomorrow, but I think I remember reading somewhere that it needs slightly warmer temperatures.

If I can't do it tomorrow, it seems unlikely I'll ever get a time to do it between rain and temperatures.

Sure - try to do it after lunch if you can when the temp hits 60°F +.

Should I wait to do it tomorrow till the grass dries some after yesterday's rain? I could do it this afternoon, if it won't hurt anything, but wasn't sure if I should let it dry up some or not.

Here is a pic, nearly 4 weeks after first round of post emerg spray. Also got the pre emerg down in between as well. It certainly didn't clear out all of the weeds, but it did seem to stunt the growth of a lot of them. Hoping to see even better results after round 2.

If the blades of the grass have dried it will be fine to spray. Don’t worry about moist ground.

Your updated photo seems to be a big improvement from your earlier photos. Much of those remaining weeds are annual bluegrass (Poa annua) and as been mentioned in some other threads that is a bit of difficult cool season weed to kill with post-emergent herbicide, but atrazine is the most effective, and you’ll be spraying that with your second application.

The good thing is the Poa will die on it’s own when the temps hit the 90s, and application of pre-emergent herbicide this fall will do great job of controlling the Poa going forward so you won’t have as much to deal with next spring.

Crawdude, if I already made the mistake of putting down weed and feed can I still redo the lawn with the recommended winter weed mix?

Did the Weed & Feed contain Atrazine as the weed component? That the most common herbicide used in weed & feeds but there are other herbicides used in other weed & feed formulations. So check the bag you used and if you threw it away check on-line.

If the weed and feed you used contained atrazine, then don’t use the weed cocktail mix, but rather you can use the weed free zone alone, with surfactant, so in essence you’ll kind of be using that winter weed cocktail.

Again, just to point out, weed & feeds aren’t inherently bad, it’s just still a little early to be fertilizing lawns now, but certainly not too early to be controlling weeds. So it really it’s a “best timing” issue.
