This application contains fertilizer along with a pre-emergent herbicide. Everything FertilizerDelivery.com does is weather sensitive, not time sensitive. Meaning, you will receive the pre-emergent for the current weather condition depending on if the spring warms up faster or stays cooler longer. Consider FertilizerDelivery.com your personal Golf Course Superintendent for your lawn.
What are Pre-emergent herbicides? Pre-emergents are designed for application before the targeted weed germinates, and are an effective preventative method for controlling weeds. Pre-emergents establish a chemical barrier that will not kill established plants, but will prevent weeds from successfully growing. The protective barrier breaks down over the course of the summer lasting for a period of 6 months. This process happens through sunlight, temperature, traffic, rain, etc. Use of a pre-emergent, therefore, requires proper timing to be effective – apply them very early in the season when the soil temperature reaches 55 degrees. As a rule of thumb, the best time is between when the forsythia shrub and the redbud tree blooms. Be aware that pre-emergents can harm some desirable ornamental plants and turf grasses. As always, read and follow the manufacturer’s instructions.
FertilizerDelivery.com will deliver either Barricade or Dimension herbicide with fertilizer. Barricade will be delivered if soil temperatures stay below 55 degrees and Dimension will be delivered if soil temperatures rise above 55 degrees. Dimension will be used if soil temps rise above the 55 degrees because of it post-emergence control of crabgrass.
