glyphosate doesn't work well for me. Am trying Ortho Nutsedge ready-to-spray. I don't have that much so having it in a spray bottle is perfect.

Ok, I was thinking glyphosate had to be effective, just not practical usually.

There are some plants that seem to be immune to glyphosate. Maybe they just need a better sticker in the tank so the glyphosate doesn't roll right off.

Forget glyphosate for nutsedge, it only kills the top & has no lasting effects--The plant will produce new leaves from the existing root within a week. Get a sedge specific herbicide that can move through the shared root system & persists in the plant. Image, sedge ender, ortho nutsedge, sedgehammer, dismiss, or another sulfur based herbicide labeled for sedge control. Sedge ender is my favorite, results in about 24 hours

Ok, folks sounds like a plan. I'll look for those products.
