Yellow Sweet Clover (Melilotus officinalis)
Yellow Sweet Clover is a biennial weed identifiable by its trifoliate leaves and small, sweet-smelling, yellow flowers. This weed, originally from Eurasia, is often used as a green manure or forage crop but can become invasive in lawns and gardens.
Controlling Yellow Sweet Clover requires timely and thorough removal. As a biennial, this weed lives for two years, producing foliage in the first year and flowering in the second. Removing the plant before it flowers and sets seed is essential to prevent spread. When pulling the weed, ensure to remove the entire root to avoid regrowth. If the infestation is widespread, a selective broadleaf herbicide can be a practical option, as long as its application aligns with the product’s instructions and safety precautions.
Bindweed (Convolvulus arvensis)
Bindweed is an invasive perennial vine with arrowhead-shaped leaves and trumpet-like white or pink flowers. Often mistaken for Morning Glory, bindweed can become a major problem due to its aggressive growth and ability to reproduce both through seeds and its extensive root system.
For successful bindweed management, persistence is key. Regular, diligent removal of the vine from the surface can gradually weaken the plant and reduce its root reserves. If the infestation is extensive, the use of a systemic herbicide, which the plant absorbs and transports down to its roots, might be required. However, care must be taken to ensure that the herbicide doesn’t affect desirable plants. As with many of these tough-to-control weeds, it may take more than one season of diligent effort to gain control over a bindweed infestation.
