Hello, I am noticing more and more dame's rocket in my woods and think that I need to start doing something to control it before it takes over. It is flowering right now. I know it's a biennial and so will die back after flowering. Here is my question: can I just go around and remove the flower stalks and throw them on the ground or do I need to bag them and take them to the dump like I do with garlic mustard? Thanks so much, Angela
