So is this something I should be planning to do, along with the spraying I just did?

Yes

If yes, when would I do it? And what would I need to spread?

ASAP this week if you can. Either granular Dimension, or granular or spray version of Prodiamine. The spray version should be cheaper per application. Your choice. And re-apply again in mid- to late September/early October. Wherever you bought the other herbicides should be able to fix you up.

Your schedule looks good, and remember these herbicides need time to work - expect 2 to 3 weeks to start seeing weeds turn yellow and dying.

Anything else I'm missing?

Lawn fertilizer, probably around mid-March/early.April.

So this isn't the same as MSM?

Seems like the list is growing and growing. Is there any particular fertilizer I should use?

MSM Turf (metsulfuron methyl) is a very effective post-emergent herbicide with no temperature restriction, meaning you can use it during the summer, if needed, (temperatures in high 80s/90s) without damaging the desirable lawn grass. The atrazine and weed free zone will damage lawn grass at those high temps. Based on the photos you posted I suspect you likely need to spray additional weeds in the summer. There is no magic bullet herbicide that controls all weeds.

Lawn fertilizer, any good extended release fertilizer formulated for lawns, something like this LINK

If your not using at least 1/2 dozen chemicals between herbicides, insecticides, fungicides and fertilizers on your lawn, you’re not doing it right.

Got the pre emergent down today before the rains came. Not sure if I should have waited till Thursday, after the rain passed, but the guy at the feed store said it was perfect right now to put it down. He's been super helpful, and pretty much echoing what Crawdude has said.

I noticed, when I was spreading it, that some of the clovers/weeds are starting to lay down and turn yellow. I'm assuming this is a good sign that what I did over the weekend is starting to work.


I'll try to remember to keep documenting this thread with pictures throughout the process.

Probably kind of hard to tell from that image. But that is 3 days after spraying the weed cooktail Craw suggested. You can kind of tell they are turning yellowish and starting to fall over.

I sprayed Saturday and that’s about what my yard is looking like.

I’ve been told it takes about a week before you really see the die off.

Any suggestions on a sprayer for a medium-large size lawn? Back yard is about 1/3 acre, so something with some capacity and coverage?

What I use this time of year for lawn weeds (St Aug, Centipede, Bermudagrass and Zoysia), and most of what you are seeing now are cool season annual weeds, is the winter weed cocktail of 8.6 ounces of Atrazine, 1 ounce of Weed-Free-Zone and 2 teaspoon of spreader sticker (surfactant) mixed in 1 or 2 gallons of water and sprayed over 1,000 sq ft. But I’ll spot spray it as well.



Are you saying you mix this up and spray your entire yard, just where you see weeds, or a mixture of both?

If your weed problem isn’t that bad, you could just spot spray. I did my entire yard cause it’s a mess.

4 gallon backpack sprayer would suffice. I have 0.65 acre and had to refill mine several times, but it did the trick.

For the winter weed cocktail, did you find a one shop stop to get all the ingredients or did it take a few different stores?

Well for a serious weed infestation throughout a yard, spray the entire yard. There may be many seedling weeds that you don’t even notice as you focus on the larger more visible weeds, and the small weed seedlings are easily controlled.

But where weeds a scattered or intermittent in the lawn, just spot spray them. You’ll find if you use lawn pre-emergents at least twice a year, you’ll likely only be spot spraying for weeds, unless you come across a weed not controlled by pre-emergents, nutsedge for example.

Craw, I've been reading up and trying to lock in my schedule to follow. Does this sound about right.


Early Feb - Cleggs post emerg spray (already done)

3 weeks following - Repeat Cleggs post emerg spray

Early-Mid Feb - Pre Emerg dimension, (already done) to try to prevent summer weeds

March - (when weather warms up above 85 for consecutive days) MSM turf, spot spray on weeds that still exist.

April - St. Aug fertilizer

Mid April - re apply pre emerg

June - St Aug fertilizer

August - St. Aug fertilizer

October - pre emerg dimension (to help prevent winter weeds)


Does this all sound correct?

One more question. You had said you weren't sure about weed and feed for me yet. Is there a time I should do this, or just stick with my above schedule?

Stick with your schedule. It will be more effective and eventually as your weed problem gets under control and your st aug fills in you can eliminate some of the post-emerg spraying and fertilizing in the summer. Some people require just spot spraying as weeds pop up because there are so few.

Thanks. Does that schedule cover everything, except for maybe spot sprays from time to time?

You will prob need to spot spray in June, July and August with MSM.

I would spray Weed Free Zone in March/April instead of the MSM.

Doesn't the MSM come into play when the temps rise above 85 consistently? I thought the other stuff damaged the St Augustine if it was applied when temps were too high?

Just looked it up, it is 85. I thought the temp restriction was mid 90's consistently.

Not sure it will consistently be 85 degrees in March/April.

I only spray Weed Free Zone early to let the weeds see a different chemical before having no choice but to spray MSM in the summer. What you're doing will be fine.

By any chance do you know if you have the Virginia Buttonweed?? It's dormant now so you won't see it, but maybe you noticed it this pass summer?

Nah, if you read through this thread, you'll quickly notice that I don't know my arse from a hole in the ground when it comes to types of grass/weeds.

Everything I have said comes from Craw's advice, and then I started reading up on it more once I had a general understanding of what I was doing.

As Balls and PeeJack have suggested stick with the schedule you outlined. Pass on on the Weed&Feed, and just use standard lawn fertilizer, provided you follow up with that second spraying of Atrazine+Weed-Free-Zone.

And read this from the LSU AgCenter Horticultural Hints Spring 2020 newsletter I received earlier today. Note Dr. Strahan recommend a follow up application of pre-emergent herbicide in mid-April and that might be a good idea in your case given the current situation in your lawn. That will also likely have the benefit of reducing, not eliminating, spraying weeds this summer.

And lastly when you get around to cutting grass you’ll want to set your lawnmower to cut grass at 3 to 3 1/2 inches, recommended height for St Augustine, and that will help with weed suppression
