5. Buckhorn Plantain (Plantago lanceolata)
If Canada thistle becomes rooted, the best control is to stress the plant and force it to use stored root nutrients. It’s at its weakest during the flowering stage in summertime; this is a good time to begin cultivation and destroy the roots and rootstock. One season of cultivation followed by a season of growing competitive crops such as winter rye, will go a long way toward eradication.
Bindweed can grow through many mulches so you need to use landscape fabrics such as polypropylene and polyester or mulches such as black plastic or cardboard but also ensure that the edges of the covering overlap so that the bindweed stems can’t find their way into the light. If holes are made in the fabric or plastic for plants, bindweed will grow through these holes. A landscape fabric placed over soil then covered with bark or other plant-derived product (e.g., organic matter) or rock will likely keep field bindweed from emerging. It might take more than 3 years of light exclusion before the bindweed dies. Once landscape fabric or other mulch is removed, new bindweed plants might germinate from seed in the soil; be sure to monitor the site for new seedlings.
