Which weed sprouts from rhizomes?

• A. Bermudagrass
• B. Sandspur
• C. Crabgrass
• D. Dandelion

Answer: (A)

Understanding how a weed spreads helps you predict what it will do after control attempts. Rhizomes are underground stems that run horizontally and produce new shoots at intervals, letting a plant spread and persist even when the top growth is damaged. Bermudagrass uses these underground rhizomes to expand and recolonize areas, so it’s the weed that sprouts from rhizomes. The other weeds don’t rely on underground rhizomes. Sandspur mainly propagates by seeds and forms prickly growths in the turf. Crabgrass mainly spreads by seeds and, in some cases, above-ground runners called stolons rather than underground rhizomes. Dandelion has a deep taproot and reproduces by seeds and root buds, not rhizomes.
