Top Comments
- For general broadleaf weeds 3-way 2,4D, mecoprop, dicamba
- For stubborn broadleaf weeds (chickweed, clover, wild violet, virginia buttonweed, creeping charlie) - triclopyr
- For crabgrass - quinclorac + methylated seed oil as surfactant
- For sedges - sulfentrazone
RoundUp for Lawns should target all of the above with a single mix. Combined with timely pre-emergent applications (early spring for crabgrass, late summer for Poa Annua if applicable), that should cover 99% of weed situations.

For a lawn care illiterate, is there a magical do-it-all product or cocktail mix that will do a decent job controlling the weeds(pre and post) in Illinois? Or am I better off continue paying $500 yearly for a "pro" service?

overseeing to ensure bare spots are filled to reduce weeds, healthy should blagh blagh blagh...never ending cycle
If you're sure it's crabgrass, then by all means go for a product with quinclorac in it. I'd suggest researching your options a bit, though - just about any product that says it kills crabgrass will contain quinclorac. You can likely find concentrates that will be much cheaper in the long run.
https://www.domyown.com/ is a good place to research products, you can just search for 'quinclorac' or 'crabgrass' and find suitable products. Note the concentrations, like 2% vs 4% quinclorac. Find a few products that look promising, then hit up Amazon for a better price, lol.
That's why you add triclopyr [amazon.com] to the mix - it reduces the bleaching effect while increasing effectiveness. I use a tank mix of 1/2 tsp mesotrione, 2 tsp 60% triclopyr, and 1 T surfactant per gallon of water.

I found threads online for both ivy and bamboo saying "I planned it many years ago because I thought it'd look good and now I'd like to get rid of it." The comments haha!
Anyone have any tips for ivy or bamboo?
On the other hand, it's good for getting rid of Bermuda grass that's crept into your cool season lawn.
Don't have any seller suggestions, but the best grass to use for shaded areas of a cool season lawn is a fine fescue. Creeping red, sheep, hard, or chewings fescue - basically any fescue that you see that's not tall fescue. IIRC creeping red is the most shade tolerant of those.
I had beautiful grass in the shade that almost 100% got roasted even with proper watering.
