Golf courses in the Southwest are overseeded with annual bluegrass to provide green color during the winter.

• A. True
• B. False
• C. Depends on weather
• D. Not practiced

Answer: (B)

Overseeding is used to keep greens looking green in winter when warm-season grasses go dormant, but the choice of grass species depends on the climate. In the Southwest, annual bluegrass isn’t the typical winter overseed because it doesn’t hold up as well under the region’s hot, dry summers and varying winter conditions. It can produce seedheads, struggle with quality and density, and require more intensive maintenance. Instead, courses there commonly use perennial ryegrass (or similar cool-season grasses) for winter color, which provides a more reliable, durable green through the winter months. So the statement isn’t accurate for the Southwest.
