Lawn weeds thrive in marginal environments where competition from turfgrass is minimal. Broadleaf lawn weeds are easily identified from grass by their broad, rounded leaves and are among the most aggressive and challenging to remove of all lawn weed types. Spreading by seeds, runners and underground stolons, broadleaf weeds are highly adaptable and opportunistic.
Sheep sorrel (Rumex acetosella) is a perennial weed with an aggressive root system that can quickly invade and choke out competing turfgrasses. With green, arrow-shaped leaves that extend from multiple stems, sheep sorrel is easily identified but difficult to remove.
Cinquefoil (Potentilla simplex) is a perennial weed that thrives in infertile soil conditions. Spreading by the use of above-ground runners that form nodes and new root structures, cinquefoil has bright yellow flowers and is often confused with wild strawberry.
Centella (Centella repanda) is a perennial weed that prefers sandy, moist topsoil. Low-growing and fast-spreading, centella has oblong, rounded leaves that point upward and inconspicuous green flowers that grow at the base.
Bindweed (Convolvulus arvesis) is a low-growing, perennial weed that forms dense mats that are difficulty to control. With broad, arrow-shaped leaves, bindweed has a deep, pernicious root system that can quickly out-compete established lawn grasses.
Beggarweed (Meibomia purpurea), often confused with common clover, is a perennial weed with woody stems and rounded, oblong leaves occurring in triplets. With flat, hairy seed pods that stick to animals and drop off in new locations, beggarweed is easily spread to home lawns and is much tougher to control than common clover.
