Hey, yall want to get ahead of thistle now is the time! Established thistle can be hard to eradicate because of the large root in the ground that stores the plants energy. It's easy to kill the top but the it comes back.
Right now thru March thistle crowns are spreading and growing and are very vulnerable and they are relatively easy to find. Hit them hard with a strong mix of gly with a good surfactant and hurt them bad, mix in a little crossbow and be done with that one.
While you are at it look for mullen or lambs ear. It grows in the same soils that thistle likes and where I find one I often find the other.
