Best strategy to control Shotweed (Cardamine hirsuta)?
So Shotweed is my #1 nuisance weed I'm trying to control/eradicate. For those of who are winning the battle with it can you recommend what you found to be the best strategy?
What I'm currently doing is putting a thick layer of Cedar Grove Compost in the planters that are prone to have it hoping I smother out seeds never to see them again (will this work?). I obviously try to pull and dispose of plants I see before they get to flower/seed.
I'm also curious what anyone knows about how long the seeds are viable, if given water do they all leaf out at once? or only some at a time and others leaf out later?
I've fought a battle with Herb Robert for many years and rarely see them anymore, am hoping I can do the same with Shotweed. I'm also starting a battle with Creeping Jenny in the lawn in about 6 small patches, trying to eradicate it before it spreads.
