Shot weed looks much different when it goes to seed than when it just flowers. I did not realize at first from the photos that it was the same weed. I did not used to have it in this yard. Obviously it could have flown in from anywhere, but I am now suspicious of the compost/soil enhancers I have put down. Bummer!
On the “neighors with weeds” front, I put down some landscape fabric and kind of curved it up onto my fence. It helped to control the morning glory vines that were coming under the fence. It still required my pulling up the vines to some degree, but it atleast helped contain them (they would still run under the weedcloth). I considered putting in some sort of rigid metal or plastic “plate” vertically to stop them….but I never did! The landscape fabric lasted pretty well. we moved from that house after 4 years and it was still in place…although not 100% intact.
