Which perennial grassy weed is difficult to control and has a coarse texture with broad leaves?

The correct answer is tall fescue, which is known for its coarse texture and broad leaves. This perennial grassy weed is particularly challenging to control due to its deep root system and adaptability to various environmental conditions, including drought and heat. Tall fescue can establish itself in turf areas, outcompeting desirable grasses and making it difficult for lawn care professionals to eradicate.

In comparison, nimblewill is generally easier to identify and manage due to its fine-textured leaves and specific habitat preferences. Wild onion has a distinctive appearance and can be treated effectively with herbicides designed for broadleaf weeds. Annual bluegrass, while problematic as an annual weed, has a different growth pattern and lifecycle, which usually simplifies its control compared to the more resilient tall fescue. The characteristics and adaptability of tall fescue are why it stands out as a particularly troublesome weed in turf management.
