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.
