What is an important characteristic of warm-season grasses?

1. They thrive in cooler temperatures.

2. They grow best during the hottest months.

3. They require less water than cool-season grasses.

4. They have deeper root systems.

The correct answer is: They grow best during the hottest months.

Warm-season grasses are specifically adapted to thrive during the hottest months of the year. This characteristic is fundamental to their growth pattern and health. These grasses typically begin to grow when temperatures consistently reach around 70°F (21°C) and will continue to grow vigorously through the peak summer heat. This growth pattern is in contrast to cool-season grasses, which flourish in spring and fall when temperatures are cooler. Due to their development during warmer periods, warm-season grasses are particularly suitable for regions with high summer temperatures. They play a vital role in maintaining a robust lawn in these climatic conditions and are often preferred for applications in southern regions where high heat is the norm. The adaptability of warm-season grasses to heat makes them a popular choice for homeowners and landscapers aiming for a thriving lawn or landscape design in warmer climates.
