Question : What if it’s over 90 degrees everyday can I use this product at night when the temperature drops below 90?
Answer : Spray Ortho WeedClear Lawn Weed Killer Ready to Spray: For Northern Lawns when daytime temperatures are consistently above 45° and below 90° (Below 85° for Bermudagrass). Ideal daytime temperatures are between 65° - 85°F. Do not apply if air temperatures are expected to exceed 90°F. On Bermudagrass, do not apply if air temperatures are expected to exceed 85°F. At high or low temperatures, weeds and grasses shut down to protect themselves and will not readily absorb enough weed killer to be killed. Hot temperatures also increase the risk of damaging the lawn. If temperatures get above 90°F the day of application we recommend you water the lawn in order to reduce potential of lawn damage at these higher temperatures.

Question : How long does it take for the weeds to start dying? I sprayed this 5 days ago, followed all the directions, and there are no signs of weeds dying yet.
Answer : In ideal conditions, visible results can be seen in hours. When the weeds are young, well-watered, and temperatures are between 65°-85°F, the results will be seen more quickly. Visible results will take longer if weeds are more mature, watering is inconsistent, temperatures fluctuate and are higher or lower than 65°-85°F. It can take 14 to 28 days for weeds to be completely controlled to the roots.
