What if it’s over 90 degrees everyday can I use this product at night when the temperature drops below 90?

Hi Paul, 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.

How effective is this product. I carefully spread this product this past week. Yet today, clover and other weeds still show.is this product any good?

I find the best is to turn the irrigation off for a couple of days after application. My yard was completely overtaken by clover. It is not a onetime deal. I am into my 3rd application after waiting the 21 days in between applications. Hopes this helps.

is this product available for shipment to New York?

No I got this. Sorry, this item can't be shipped to your selected address. Learn more. You may either change the shipping address or delete the item from your order.

Would I need to remove the crabgrass and weeds from the lawn and flowerbed from the root after spraying this product and it turns yellow ?
