What type of grass tends to grow in clumps and is difficult to control?

The correct answer is tall fescue. This type of grass is known for its growth habit, which is characterized by forming clumps or tufts rather than spreading evenly across an area. This clumping nature makes tall fescue less desirable in turf management because it can create an uneven appearance and complicate control efforts when trying to manage the area.

In terms of turfgrass management, controlling tall fescue can be particularly challenging because its clumping growth allows it to resist some mechanical control methods, such as mowing or herbicide application, aimed at promoting a uniform turf. Additionally, tall fescue has a relatively deep root system, which can help it survive in various conditions, further complicating eradication efforts.

Understanding the growth characteristics of different grass types is essential for effective pest control and turf management. Knowing that tall fescue tends to grow in clumps can help turf managers make more informed decisions when it comes to choosing the right management practices and control strategies.
