Chemlawn laid down the first weed pre-emergent and fertilize the turf on February 11 and 16th.They came back in March (no charge) to respray the last bits of clover alive and on the property.
On April 19th, the yards were treated a third time - pre and post emergent and liquid fertilizer.
Preemergent weed control uses products that are designed to work before a plant germinates in early spring. For difficult annual weeds, multiple applications may be required—first at the start of the spring and then at a timed intervals as secondary flushes of germination come on as the seasons progress. This extra control is for difficult weeds and the idea is to take another shot at it before it has produced flowers or seed heads.
