Both broadleaved and grassy weeds can exist as winter or summer annuals.

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

Answer: (A)

Weed life cycles in turf depend on timing, not plant type. Both broadleaf and grassy weeds can have winter annual or summer annual life cycles, depending on the species and climate. Winter annuals germinate in fall, overwinter as young plants, then flower and set seed in spring; they often die as temperatures rise. Summer annuals germinate in spring or early summer, grow through the warm season, produce seeds by fall, and die before winter. This is why both broadleaf and grassy weeds can fit either pattern. Examples help visualize it: a winter annual grass is annual bluegrass, a winter annual broadleaf is common chickweed; a summer annual grass could be foxtail, and a summer annual broadleaf could be purslane. The key idea is the germination timing drives the annual behavior, not whether the weed is a grass or broadleaf, so the statement is true. This timing difference also guides when and how to apply controls in the turf.
