Fall is just around the corner, which means it’s time to think about Fall Pre-emergent weed control. Weeds are categorized as either broad leaf or grassy type weeds. A Pre-Emergent herbicide controls unwanted weeds and grasses by targeting the weed seed just before or immediately after the seed begins to germinate. Generally most pre-emergent are safe to use around established trees and shrubs as well as most ground cover. A pre-emergent should never be used in areas where seeds or bulbs have been planted or will be in the near future. Fall is also a great time for pre-emergence in areas where there is no irrigation because of rain fall, pre-emergence must be watered in to activate. At custom Ag we do pre-emergence in all areas of your landscape including: flower beds, landscape beds, lawns, open land i.e. fields, vacant lots, bare ground etc..
