St. Augustinegrass has greater low-temperature hardiness than tall fescue.

St. Augustinegrass has greater low-temperature hardiness than tall fescue.

• A. True
• B. False
• C. Not sure
• D. Unknown

Answer: (B)

Low-temperature hardiness tends to be higher in cool-season grasses than in warm-season ones. Tall fescue is a cool-season grass, so it stays active and survives better during cold winters. St. Augustinegrass, being a warm-season turf, enters winter dormancy and has comparatively limited cold tolerance. In practical terms, tall fescue generally handles freezing temperatures and winter stresses better than St. Augustinegrass. So the statement is not correct; tall fescue has greater low-temperature hardiness. Variations exist among cultivars and local conditions, but the overall trend holds.
