    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.

    Shot weed can come from plants bought at nurseries (as can snail eggs..)

    Yeah, the snails are definitely fairly new; they don’t survive once I spot them. I DO remember seeing bittercress/shotweed around here in my youth, but don’t remember it being so widespread.

    I’ve heard that the seeds make it through the filters at Cedar Grove and it ends up in the mulch we buy. Not sure about the compost. The root system is so shallow that weed fabric won’t prevent it- it grows on top of it.

    Hammertree you said what I have been thinking for a few years. I (and my Mom who lives in another area of WS) both got mulch from Ceder Grove and we have had real problems with shotweed. Plus I had weed fabric installed prior to the mulch being spread and sadly the weed fabric seems to have been a bust due to all kinds of stuff growing right on top of it. Note the one thing that really kept the shotweed down was pouring a ton of Preen all over the yard in very heavy doses.

    I must add that the benefit the mulch provides far outweighs the shot weed problem. The weed is easy to pull (easier to pull after rainfall).
