We recommend using an early spring granule pre-emergent treatment to minimize the amount of germination that occurs during this time period. Many weeds sprout at different times thru-out the year depending on weather conditions. DC Landscape and Maintenance recommends a post-emergent weed spray that contains a pre-emergent ingredient.
The pictures here represent a yard that was infested with weeds. We sprayed the weeds to kill them at the root, and later removed them after they were dead. Many times people or other landscape companies will simply pull weeds without spraying them. If the roots aren't fully removed, the weeds will generally grow back. That is why we will typically spray first, and then remove the weeds once they are dead.
