Which of these weeds has a thick root that extends deep into the soil?

The broadleaf plantain is characterized by a thick, deep-rooting system, allowing it to access moisture and nutrients from deeper soil layers. This trait gives it an advantage in survival, especially in conditions where competition with shallow-rooted plants occurs or during periods of drought. Broadleaf plantain can thrive in a variety of environments, including disturbed soils and lawns, primarily due to its robust root system. This deep root structure also enables it to withstand mowing and other forms of physical disturbance better than many other weeds. Understanding the growth habits of broadleaf plantain can help in the development of effective management strategies for maintaining healthy turfgrass and minimizing the impact of this weed.
