I am battling an invasion of thistle trying to take over the entire yard. I believe it is too late this year in Colorado for pre emergents as I see small thistle plants actively sprouting throughout the grass and rockbeds. The product needs to be safe for children and pets within a few hours after application.
You can use Lontrel to treat grassy weeds like Thistle. Lontrel is a pre-emergent that works great in treating thistle. Please read the product label to make sure you can apply this product your lawn.
