Crab grass dies in the winter, here in the south in NC this product needs to go down around mid February usually, when there is forsythia blooming as mentioned. This acts as a blanket so to speak and it prevents the crabgrass seeds from germinating. Before you put it down you can get down close and look at your lawn and you'll see tiny little green sprigs everywhere if it has already sprouted. If you see it at all then you are too late and this product is useless.

If you already have it then what you want is Quinclorac. It expensive but it works. You don't need name brand, any Quinclorac powder will do. I mix 1 TBSP per gallon and it kills the crabgrass dead. You'll see it all turn yellow and die within two weeks. I have bermudagrass it doesn't harm it. If you're putting that down, add in some 2-4D at 1oz/gallon. That kills every broadleaf weed. That's much cheaper than Quinclorac, which usually costs about $65-$70 for a seasons worth. 2-4D is about $20 for a gallon, which yields 16 gallons. One more thing I put in mine is MSM powder which kills ryegrass. I mix all 3 together and spray it about once every 4-6 weeks because my neighbors have a yard of weeds that blow over and it kills every single weed, ryegrass, and crabgrass. I used to work for Scott's back in the day.

I'm not lawn expert but I believe if you put this down in early spring it acts a a pre-emergent and stops the crab grass from germinating. Once it's germinated this does nothing to kill it.

What is even the active ingredient? It's usually in a box on the front bottom but nothing in the photos and I didn't see "active" in a quick scan...

This could easily help or kill any random lawn.

It says it has lawn food, I'm guessing nitrogen? it also mentioned "green" so I'm thinking iron but it does not specifically state the ingredients

30% Nitrogen
0% Phosphorous
4% Potassium

No iron in a product like this, need to buy something like ironite. A fertilizer like this feeds the grass, making it grow, while something like ironite will just make it greener (theoretically). Depending on the PH of your lawn would want to put down sulfur or lime with the iron. Typical ph between 6 and 7. If you need to raise the ph then put down lime, if you need to lower it put down sulfur. Iron stains concrete, so if putting down with a spreader then be sure to blow off the concrete if you have a concrete driveway. Don't put down iron when it's hot, or you'll burn your lawn. I like using iron more than fertilizer because it makes it nice and green without making it grow like crazy

Specifically the "weed" part is whats making or breaking this product, and a crabgrass premergent could be something like atrazine which is fine for st aug, but would be bad for bermuda, etc. Lots of scenarios here so that fact that it is hard to find and not on the product image is just asking for bad reviews, let alone ruined lawns.

No. Store in cool dry place (basement/garage) and it will be fine for next spring. Wayy too late to apply for crabgrass alone right now, although it does control other germinating grasses and broadleaf weeds. Most use this pendimethalin for crabgrass, though.

use this site to learn when to apply it. There is also a soil temp page to see what week you should put it down in your city. https://www.canr.msu.edu/news/tim...plications

Same price as home depot. You gotta watch Amazon's price manipulating. They take the discount off the suggested retail price that literally nobody sells something for.
