Spotted kapweed poision info.

19 years ago

If you pull out Knapweed is it safe to replant with Natives say a few weeks afterwards, How long does the poison last in sandy soil?

I'm doing a restoration of a riverbank, at a city park, that's infested with Knapweed, I'm on my second year and the weeds are pritty much gone.
