So I was wondering if anyone can tell me about results you've gotten with Tenacity. I've never really had the need to use the stuff before and am not familiar with it. I have a lot of patches of bentgrass in a tall fescue lawn. The lawn is actually mine (moved into a new house) and just noticed the stuff really spreading rapidly. I'm planning on maybe late July/early August to start. Is this like treating Bermuda in fescue where its a constant battle with 3 apps per year? Or will it knock this stuff out with an initial treatment and then one follow up? The good thing is the Tenacity can be applied with seeding or right after if I need a second app. Anyone who could post about this product or your experience with it on undesirable grasses in fescue would be great.
