Annual bluegrass is more drought resistance than perennial ryegrass.

Annual bluegrass is more drought resistance than perennial ryegrass.

• A. True
• B. False
• C. Not sure
• D. It depends on cultivar.

Answer: (B)

Drought tolerance among cool-season grasses is influenced by root depth and water-use efficiency. Annual bluegrass typically has a shallow root system and is more sensitive to prolonged dry spells, often suffering under drought. Perennial ryegrass, on the other hand, develops a deeper and more extensive root network that supports better water uptake during dry periods, making it more drought-tolerant. So the statement that annual bluegrass is more drought resistant than perennial ryegrass isn’t true in the usual turf context. While there can be variation among cultivars, the general trend is that perennial ryegrass handles drought conditions better.
