I've had problems with nutsedge in my yard for the past 2 years. Last year, I treated it fairly late in the season(August I believe) with Sedgehammer from Lesco and it did a good job of killing them off within a week or so. This year, I've been using Tru-Green to treat my yard. Indiana has had a VERY hot/dry season, so of course, that's the excuse they're giving about crabgrass and everything else under the sun. They've been out at least 3 times to treat for weeds/fertilize and had callbacks every time to kill off the nutsedge and haven't gotten rid of it yet. The guy who treats my yard left me a message saying they'd be unable to kill it because the nutsedge was "too mature" and pulling is the only option of killing them off. I say they're full of it because the Sedgehammer I used last year was very effective. I've been very unhappy in their ability to kill off these weeds. I specifically told them not to treat my yard 2 weeks ago until this situation was resolved and yet, they came out again last week. They've not returned calls asking how they're going to resolve this, yet they've called numerous times to upsell every other service they have. I've told them I'm not paying for my last treatment as well. Any advice other than eating the cost out of my pocket to get some Sedgehammer?
