We do not recommend using Dimension Ultra 40WP with a hose end sprayer application. It is made for larger tank applications because you need more water to distribute the product. Please see the tables on the product label for these distribution rates.

Dimension Ultra 40WP should be applied prior to weed germination. The general rule is to apply your pre-emergent herbicide treatment after the ground has thawed from the winter but before the temperature of your soil reaches 55 degrees, as that is when crabgrass begins to germinate. Other weeds will germinate when the soil temperature is between 55 and 65 degrees. You can use a soil thermometer to determine the temperature of your lawn. You will want to measure the temperature of the soil a few inches below ground.
You may contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region or search online for best time to apply in (your area). A lot of universities have great articles for this.
