I'm wondering if I can use corn gluten on my established asparagus bed for weed control. Also could it be used in onion transplant beds. Any details on usage, would be helpful as well. Thank you,

We do not have research on corn gluten in vegetable beds. For weed control we recommend cultural practices such as mulching, handweeding, and cultivation.
