Can you advise how one would remove burdock from an asparagus patch?
Charlevoix County Michigan
Controlling burdock when it is a small seedling is the best time to control this weed. If the asparagus is more than a week from emerging spears you can treat with glyphosate. Pre-emergents listed for use in asparagus can be used to control seeds. Remove burdock seed heads to prevent reseeding. Check out the following links:
