Bull Thistle Management

[Shelby Bauer]

Does anyone have experience or advice in managing/treating for bull thistle that they could share?

[Katie Grzesiak]

Manual removal is most effective before it flowers.  Asparagus knives (something like this) or other weed forks are really great for getting out the taproot.  You can use herbicides too, but get excited about surfactant because it takes a fair amount to penetrate the crazy trichomes/prickles.

Thank you Katie!
