I should have clarified. For the spring application, you should apply before the soil temps reach 55 degrees for roughly 5 days.

You can enter your zip code to see the recent soil temps along with the trends.

Note, areas that get more sun or are near concrete or brick might warm up faster than other areas. So you're better to do it a little earlier than too late.
This is a good deal. People should be putting this product down within the next 3-4 weeks around most of the country to minimize the amount of crabgrass popping up in the summer.

$20 of this product now will save countless hours and $ later trying to remove crabgrass.
It is the ground temperature you want to watch for - like 55 or so.

Pre-emergents should be applied at least twice a year. As previously mentioned, they should be applied in the spring before the ground temperature reaches 55 degrees Fahrenheit. Then it should be applied again in the early fall after temperatures begin to come down.

But don't put this down if you are going to put down grass seed! If you do, then the seeds won't grow - the pre-emergent prevents their growth. If you have green like I do in my lawn (poa annua in my bermuda grass in NC), I will spray the bad boys with Roundup at this point - I won't have green grass until mid-May. Also check with your extension agent or your local ag school - they will have some good opinions.

I dont have a great understanding on the timing of when to use these, so forgive the ignorance, but are you saying that once temp reaches over 80, these are no long effective? Does it have to be consistent over 80s or since we are in the season where temps will dip and come back, will it not be effective on the dips (like 60s/50s)?

Lowe's carries Lysco Stonewall locally at $43 for 15k SqFt. Apply this when the Forsythia bloom.

Wow, so weird. I was just explaining this to my wife, probably at the exact same time you posted.

Quote from danteshors :
for southern states it may be too late for a preemergent. I have a yard full of weeds already.but I still put down the "real" preemergent yesterday from SuperSod. Hopefully it will kill the late blooming weeds and stifle the growing ones.

https://www.supersod.com/products/0-0-7-pre-emergent-herbicide

or for fescue lawns

https://www.supersod.com/collections/lawn-care-products/products/16-4-8-fertilizer-pre-emergent-herbicide

Note this is a 50 pound bag above from SuperSod versus Amazon 10 pound bag so compare shop ingredients!
Very wrong. You have winter weeds that need a post emergent spray(weed b gon) to kill them. In the south wait for the Forsythia to bloom full yellow to drop pre emergent like 1st week of March. It will stop new spring weeds from sprouting.

5 consecutive days or 5 days in the calendar year ?

The crappy state of CA of course bans Amazon from shipping this to me. Of course if I walk into home depot, it's probably there for 50% more. The law makers in this state are crap. Had no problem buying this back in 2018 but of course this state has going down the drain with ridiculous laws. Guess I need to make sure I vote, but it likely won't make a difference

Here in Raleigh, I'm agnostic - but I bet that UNC folks won't consult those at NC State (our Ag school) for the same reason. Besides, you could hire them to do menial tasks for you - like I do the other UT (Tennessee).

You basically sprinkle it over the lawn? My grass is pretty much dead until march/April when it starts getting warmer. Last year I had tons of crabgrass everywhere so a preventative solution sounds great if it works
Yes, but you would use a fertilizer spreader to "sprinkle" this on the lawn to get even distribution and coverage. No need to spend a lot on a fertilizer spreader - you can usually find gently used ones for cheap on Facebook Marketplace or Craigslist, especially the Scott's brand spreaders.

Thanks! I actually have a Scott spreader left in my garage by the previous homeowners that I never used. This will be my first time. Hoping for a summer without crabgrass!

It's important to note this likely won't eliminate 100% of all crabgrass. You'll still get some crabgrass breaking through, but it will be a very manageable amount that you can easily remove by hand.

One popular strategy is to spread about half the amount in early spring and then the rest about 4 weeks later to get maximum coverage throughout the summer.

You don't have to do it this way, and instead apply it all at once in early spring, but then it starts breaking down by mid summer when crabgrass germination is in full swing. Doing a split application will help keep the protection on for longer into the season.
