Glyphosate is a weed killer and the main ingredient in RoundUp.
I've owned houses for over 40 years and killed many a weed in that time.
However, this year I've got weeds that even RoundUp won't kill.
Don't know if it's stronger weeds, or weaker killer. Whatever, it's a pain in the arse.

Try Crossbow

One weed that it won’t kill is Dallas grass.

Only thing that works on that stuff is digging it out.

Will 1 gal vinegar/1 cup salt/1 tsp dishwashing soap do it?

Try this. 1 gallon white vinegar, 1-2 tbsp dish washing soap (cheapest you can find), and add lemon juice to add acidity. Spray with a pump style sprayer.

Roundup doesn’t work as well on broad leaf weeds. Try Crossbow for those. Takes a bit longer for them to die back but it kills them good.

I use Groundclear. Stronger concentration and an additional herbicide.
