Frequently asked questions

Pre-emergent herbicides are spreadable granular or sprayable liquid chemicals that form a barrier just below the soil surface and prevent cell division in seedlings. This effectively stops weeds from ever sprouting in your lawn. They don't affect mature grass or plants. Some pre-emergents like Mesotrione are specially formulated to be used at the time of grass seeding but will block future weed growth. Mesotrione has the added benefit of providing some post-emergent control of mature weeds. Prodiamine is one of the longest-lasting and most effective pre-emergents and what we recommend right after planting buffalograss plugs. It allows the buffalograss to establish without competition. Pre-emergents are generally applied in the Spring (March-May) before soil temperatures reach 55 degrees and weeds begin to germinate.
