Why warm-season grass usually wins drought comparisons
Warm-season grasses such as bermuda and zoysia are built for strong summer performance. They generally handle hot conditions better and can maintain themselves with less water once established.
Why cool-season lawns still matter
Many homeowners still want the look and seasonal rhythm of a cool-season lawn. That is why tall fescue stays relevant. It is not the pure drought champion, but it can be the best compromise.
The most common mistake in this decision
People often choose based on the most drought-hyped species without asking whether the region and desired lawn look make that choice realistic.
