What kind of grass do you have. Tenacity is not recommended for Bermuda unless it is dormant.

 

Tall Fescue.

 

You might want to check the Cool Season Lawns thread. They will have more direct experience with TTTF.

 

@Redtwin is right. Most of us on this board can’t even spell TTTF

 

Im just outside of Charlotte and have an embarrassment of a Bermuda lawn the home construction company left me. The Bermuda Bible says "There is no time like the present to apply..." in reference to pre-emergent, bu then im seeing other places say you need to wait until the soil temps are in the steady 50s.

I feel like I am doing nothing and having a hard time being patient to start this project as I didnt want to look at my yard at all last year.


The bible also references using Barricade or Dimension for pre-emergent, but from who? does it matter? It seems like Anderson is the top dog in the fight with the top price, but is it the same as Scotts or some other named company from Amazon or LowDepot?

I see Andersons sells Dimensions or Barricade...how do you choose?

 

Prodiamine is Prodiamine and dithiopyr is dithiopyr. Just follow the label.

It is warming up so put it down while you can. Waiting a week or 2 longer can cause you to miss the soil temperature window and the rain opportunity.

You will need annother app or 2 this growing season to cover until the Fall. Why wait?

Prodiamine has a longer residual for crabgrass. Otherwise they are the same residual for other weeds. Dithiopyr as a liquid will control young crabgrass, but you are using granules so it won’t provide a benefit. And if you worried about young crabgrass, then you are applying too late.

While there is science involved it is not rocket science.

 

I feel like every year I miss the proper window to put down weed preventer, and end up putting it down too late. This year I want to be on time.

I see that some weeds are starting to poke through, but is it too early? When is the best time to put down weed preventer? I am in the Raleigh area.

Also, I usually put down Scott’s products, but I also have tenacity. Which is preferred? Assuming tenacity for any areas I plan on overseeding?

Thanks!

Once in your situation, FEB 14 has been my annual “Have Prodiamine down” for at least 8 or 9 years now and ever since observing “forsythia blooms” as an utter FAILURE PATH - first in Southern Md and then Really confirmed here in NC …

There is a research paper out of NCSU where earlier germination of weeds is confirmed (crabgrass in particular), essentially natural selection, since the 50’s and 60’s (when “forsythia blooms” may have held some validity)

ETA: this is not the actual - and more definitive - paper I am scouring my bookmarks for but, it’ll have to do for now (sun is up and I’m burning daylight, now!):

When to Apply Preemergent Herbicides for Turfgrasses

When to Apply Preemergent Herbicides for Turfgrass in North Carolina It is well documented that our winter temperatures are rising in NC, as well as the rest of the US. As winter temperatures rise, so do soil temperatures. As a reminder, crabgrass will germinate when 24-hour mean soil...

“So what does all of this mean? It appears the winter of 2024 is tracking similarly to the past several years. In summary, we are ahead of the 30 year average for GDD. Also, soil temperatures can rise quickly with rising air temperatures. Therefore, it is my recommendation that preemergent herbicides should be applied earlier due to the danger of early crabgrass germination. This is consistent with similar recommendations over the last few years. My recommendation is preemergent herbicides be applied in central NC by the end of February. East of Raleigh, application should be made earlier. Mid-February would be a good target date for that area of NC.

I use this to get an idea for what is actually going on.

I’m in Coastal ENC and just put mine down on 2/11/24. This will be my second year with Bermuda. I did not apply pre emergent before sprigging and it allowed a lot of weeds to move in. Too early is less of a sin than too late. I have dallisgrass and crabgrass problems am I am NOT going through the pain of pulling hundreds of weeds again. So, you can use Prodiamine wdg with a sprayer or they sell it in a granular form. Just be sure to time it before a solid rain so you can get it down into the soil. If you are too early you can apply again in the season.

 

I purchased a Solo broadcast spreader and a 40lbs bag of Andersons Barricade last week and spread it yesterday and have been watering it in today. Fingers crossed I spread the right amount and see some sort of benefit for it. Thanks for all the info.

 

I have tall fescue. We live in Matthews, NC is it too early to apply Pre-emergent. I purchased Scott’s Triple Action. Can I apply now since it is March1, 2025

 

@tnvolfan44 No, it is not too early. Put it out now and get it watered in.

 

Now would be a good time.
Your current soil temp is about 56 deg.
