My neighbor to the east is cultivating Japanese knotweed as a privacy barrier in his backyard. It is spreading into my backyard (102 Cedar Lane) and the backyards of other neighbors. I am spraying to control it but it just keeps sending out shoots -- farther and farther into my grass. I cannot use this property for growing anything else while this stuff is there. What can I (we) do about this? Please contact me before contacting the neighbor in question. Thank you.
