Field burrweed (Soliva sessilis)

Field burrweed, known for its sharp seeds that can cause discomfort when stepped on, is an invasive weed often found in lawns and yards. To effectively manage it, consider using a pre-emergent herbicide in late summer or early fall to prevent seed germination. For existing burrweed, a post-emergent herbicide applied during its active growth period in winter or early spring can be effective. Additionally, maintaining a robust lawn through regular mowing, watering, and fertilization can help prevent its spread. Always adhere to herbicide instructions and safety measures.
