We are sorry that the Ortho WeedClear Lawn Weed Killer Ready-to-Spray did not control weeds as expected. To get the best results from this weed control when targeting spring and summer weeds such as clover and dandelions, be sure to apply the product when your daytime high temperatures are consistently between 65 to 85°F (18 to 29°C). For best results, the night time temperatures should be consistently above 50°F (10°C). For annual fall/winter weeds, temperatures should not be lower than 45 degrees. Since this product is absorbed through the weed's foliage, we recommend that the weeds not be mowed for two days both before and after the product application. This product will only kill weeds that are actively growing at the time of application, and cannot prevent new weeds from germinating. We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience, please contact us to see what can be done.

We're sorry to read about your disappointment with Ortho WeedClear Lawn Weed Killer Ready-to-Use and appreciate your feedback.Visible results can be seen after 24 hours. This product takes a minimum of 3 weeks to completely kill weeds. However, it has proven to be much more effective than faster-acting weed controls. Temperatures below 60 degrees or above 90 degrees may cause weeds to be dormant, slowing their control. Mowing 2 days before or after application reduces the leaf surface and the plant's ability to absorb the herbicide. Do not water for 24 hours after application nor apply the product when rain is expected within 24 hours.We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience, please reach out to us at 866-324-9192 if we can further assist.
