Tim if you check it closely you will notice the ants are not eating your collards, they are farming the hidden aphids that are sucking the life out of the plants. I know, I had that happen. Now if I see ants on the collards I go looking for the aphids, sure enough there they are. I give them a good blast of water and that seems to keep the aphids at bay.
I love collards. Yummmmm
