Answer 1

So glad you enjoy our newsletters! The best way to deal with weeds in your asparagus beds is probably to mulch them with straw or bark when the asparagus is a few inches tall. Of course, pulling them by hand is an option. In early spring, you can use a pre-emergent such as corn gluten meal. After harvest you can use a post-emergent herbicide.

This article mentions these options but ignore the old-time-once-used salt method. (salt can render soil useless)
