Duck pond cellars has a unplanted space out in the vineyard that has a overwhelming amount of tangy weeds growing. They don't pull them and are letting them spread. I have horses in pastures that back the vineyard, and I dig up and dispose of my tanzy weeds multiple times each season to keep my horses safe. I have even dug up some on their side of the fence to keep them out of my fields. Can they be made to control their weeds and protect my horses. I use organic sprays to protect their crops as a good neighbor. Any help would be appreciated.
