It’s best not to till an asparagus bed, as you might damage the crowns. Early in the season, before growth emerges, it is possible to use a hoe to remove weeds shallowly, but at the current stage, where you have young and ready-to-harvest spears, hand pulling is best to avoid damage. After you remove the weeds, a 3- or 4-inch layer of organic mulch, such as straw (not hay, which may have seedheads), can help prevent further weed emergence.
