LATE SEASON weed killer

I am having trouble getting the usual suspects to thoroughly kill non-broadleaf weeds even under “ideal” conditions (like early spring). I have tried Roundup and various generic variations, brush killers, soil sterilizers, crabgrass killer, weedBgon, and mixtures of all of these. They all work to some extent (like turning the weed from green to red) or on some occasions but none reliably. My most resistant weeds are versions of those small leaf plants that you find in cracks in the street (except they have invaded my yard (mainly decor areas, not so much in the lawn); I think they may be a type of “spurge”. My thought is that a chemical designed for less than ideal conditions (like a LATE SEASON weed killer) might work. Any such animal on the market? Any ideas would be appreciated. Thanks, Larry.

What kind of grass and where are you located?

Joeearney, My lawn grass is a 30 year-old northwest mix of bluegrasses and fescues for eastern WA.

I would use the same chemicals you’ve been using but, they seem to work to some extent. I would repeat the application every five or six days. I think the repeated frequent applications will take care of it. If we’re talking weeds and grass and roundup doesn’t kill them, then I think you’re not using enough roundup on your sprayer. Some of these chemicals work very slowly in cool weather.

Thanks Joeearney. So Roundup is the best I can do? When I first started gardening (25 years,now) I could use R-Up diluted and just wait a couple weeks. Now I use it full strength and more and it barely touches my toughest weeds and this is under “ideal” conditions (spring growing season, non-dusty leaves. no rain/watering for 7-10 days, etc). I sure had my hopes up that there was a product that would work in less than ideal conditions (like late-season). I’ll try strengthening the dose and repeating the applications like you suggested. Thanks again, Larry.
