Greetings! We live in the city of Grand Ledge on 1/2 acre lot. We have many garden beds including a wild area to encourage pollinators and support natural habitat. Please advise: 1. We are still battling invasive Japanese knotweed from a neighbor's stand that has not been removed. Any suggestions?? 2. We have a "new" plant that I never noticed before this year - that seems to be invading every area of the garden and growing very quickly - as high as 5-6'. I have pulled out many stalks, but as a "senior" gardener, cannot manage the whole crop! Is this Japanese hedge parsley? Can you identify and advise please!! PIX attached. MANY thanks! Barb
