I spent many summers of my youth chopping down the wily musk thistle. Still, when it came time to make flowers for my wedding in 2010, I found the fake thistles at Hobby Lobby to be very charming additions to my wedding bouquet, which I made myself.
I remember my grandpa -- a lifelong rancher -- commenting on the big day, “Amanda, do you know you have weeds in your bouquet?” I had to chuckle at his reaction, and I’m sure he will have the same response come May 30th when my sister walks down the aisle of our church carrying a bouquet full of those purple-headed weeds we all despise.
While fake thistles in a bridal bouquet might be harmless, the real musk thistles that grow in our pastures are certainly not. In the Hay & Forage Minute, Bruce Anderson, University of Nebraska-Lincoln Extension forage specialist, reminds us that it’s time to start thinking about musk thistles. “Does anybody like musk thistles? If not, how about doing something about them,” Anderson writes.

Here are three things to note about musk thistles, courtesy of Anderson:
1. Spring is the time to start thinking about musk thistles.
“With all the rain the past week and a half or so, I’ll bet you’re anxious to get into the field for planting. Don’t forget, though, that this also is the best time to control musk thistles. And I’ll also bet that you can get into your pastures to spray at least one or two days sooner than you can get into row crop fields to plant,” says Anderson.
2. If you had the problem last year, chances are thistles will plague you again this year.
“Did you have musk thistles last year?” he asks. “If so, I’m sure you’ll have them again this spring. And the current rosette growth form is the ideal stage for controlling these plants this spring. That means spray herbicides soon, while your musk thistle plants still are in that rosette form, and very few plants will send up flowering stalks for hand-digging later.”
3. Any herbicide you use will work if you spray soon enough this spring.
“Several herbicides are effective and recommended for musk thistle control. My current favorite is a relatively new herbicide called Milestone. Another very effective herbicide is Tordon 22K. Be careful if you use Tordon since it also can kill woody plants, including trees you might want to keep.
“Both Milestone and Tordon also will help control other weeds that usually appear later in the season. Other herbicides also can control musk thistles in pastures – like Chaparral, Grazon, Cimarron, Overdrive, and Curtail. A tank mix of dicamba and 2,4-D also works very well,” he recommends. Anderson stresses the importance of reading and following label instructions before using a herbicide on pastures.
“All these herbicides will work for you this spring if you spray soon, before musk thistles bolt and send up their flowering stalks,” he adds. “After flowering, though, the shovel is about the only method remaining to control thistles this year.”
