Fall is one of the best times to manage your noxious weeds. For perennials like Canada thistle, Dalmatian toadflax, and Leafy spurge, fall applications of herbicide are very effective as the plants begin to move resources to the roots. Target both the established plants and any newly emerging seedlings.
Fall is also the time to get a head start on managing your biennial weeds like Musk thistle, Diffuse knapweed, and Common mullein. Focus on the newly emerging rosettes. They can either be removed (including the top couple inches of the root) or treated with herbicide.
By working this fall, you can significantly reduce the number of weeds next spring.
