Antioch FAQ
Is yellow starthistle illegal to have on my property?
It is a C-rated noxious weed, meaning the state requires local control efforts. Owners are expected to prevent its spread, and unmanaged infestations may trigger abatement orders.
Can I use any herbicide I want on noxious weeds?
For residential properties yes, following label directions. Commercial applications require a licensed Qualified Applicator; glyphosate and triclopyr are commonly effective but check product labels for California-approved uses.
Oakley FAQ
Is pampas grass really invasive? I see it for sale.
Yes, Cortaderia selloana is Cal-IPC High-rated and spreads aggressively via windborne seed. It is discouraged for planting and some water districts offer removal incentives. Replace with native bunchgrasses like deergrass.
What should I do about Arundo along the creek?
Giant reed (Arundo donax) is a priority invasive along Marsh Creek. Report large stands to the Contra Costa Resource Conservation District and the County Ag Commissioner, which coordinate watershed-scale removal projects.
