Bluegrass and fescue grass are described as semi-dormant; fertilization is not suggested because it stimulates what?

• A. It increases growth
• B. It reduces weed growth
• C. It stimulates weed growth
• D. It causes drought

Answer: (C)

When bluegrass and fescue are semi-dormant, they aren’t actively growing. Adding fertilizer during this time provides nutrients that can spur any nearby plants to start growing quickly, and weeds are especially responsive to extra nutrients. The result is more weed germination and spread, which then competes with the lawn once growth resumes. So the main idea is that fertilization at this stage tends to fuel weed growth rather than improve the lawn. The other outcomes—reducing weeds, causing drought, or simply increasing lawn growth during dormancy—don’t align with how semi-dormant lawns respond to added nutrients.
