and tap roots, or coarse root systems
3. Woody plants - Correct Answer: brush, shrubs, trees. brush and shrubs
have several stems and are less than 10 feet tall and may be understory.
trees usually have a single stem and are over 10 feet tall.
4. Best time to control biennial - Correct Answer: first year, before
maturity
5. Best time to control summer annuals - Correct Answer: soon after
germination as seedlings in spring
,6. Best time to control winter annuals - Correct Answer: seedling stage in
fall or early spring
