I have 3 patches of thistle growing like crazy in property we cut. Been catching the patches, still spreading fast.

Anyone know a product that can be sprayed on st augustine to kill thistle.

Most all the "thistle" I saw all winter is dying all by itself (due to the heat). If one were to accidentally spill some Speedzone on it, I guess it would die quicker. However, post-emergent, selective herbicides and 95 degree heat often don't mix well.
