There are many different ways that plant, insect, and disease pests can enter Minnesota. The particular method of introduction for a pest is called a pathway. This month, as folks go to the florist to get Valentine’s Day arrangements, it is an appropriate time to explore the cut-flower industry. This is a potential pathway for noxious weed introduction. Most people would not think of a floral arrangement as being a possible source of a new weed infestation, but this can and does occur.
