The pre-emergent granules sit on the soil surface after application and must be watered into the soil to activate. Water carries the product into the top layer of soil where weed seeds germinate. Without this activation watering, the pre-emergent remains on the surface and provides little to no weed prevention. Overhead irrigation or rainfall within 24-72 hours is essential for product effectiveness.

Our first application must be completed before soil temperatures reach 55°F consistently, typically by mid-April. Once soil warms and weed seeds begin germinating, pre-emergent becomes ineffective against those weeds. Missing this early window means fighting weeds all season rather than preventing them. Our scheduling ensures optimal timing every year.
At Yard Boss, we understand that you may have questions about our services, processes, and how we can help you achieve the perfect lawn. Whether you’re curious about our lawn care techniques, service areas, or the benefits of professional lawn maintenance, you’ll find the information you need right here.

No. We take great care to protect your ornamental plants. The liquid herbicide (spot spray) only affects plants it directly contacts through their leaves, and our trained technicians apply it precisely to weeds only. The granular pre-emergent works by preventing seeds from germinating—it does not harm established plants, trees, shrubs, or perennials with existing root systems.
If your goal is to maintain weed-free landscape beds, then yes. The pre-emergent is preventative—it stops weeds before they appear. Not seeing weeds means the program is working correctly. Once you stop treatments, weed seeds will germinate and you'll be back to manual weeding or dealing with weed problems.
Breakthrough weeds can occasionally occur, especially during the first season of service as we establish control. If you notice weeds between scheduled applications, contact us. We include one complimentary mid-cycle visit during your first program year to address any breakthrough weeds. After the first year, additional spot treatments can be scheduled as needed.
Spot-sprayed weeds will begin showing signs of dying within 24-48 hours and should be fully dead within 7-10 days. The pre-emergent works invisibly—you won't "see" results, but you'll notice the absence of new weeds for the following 8-10 weeks.
Yes, when used as directed. We recommend keeping pets and children off treated areas until the spray has dried (typically 1-2 hours) and until after the area has been watered. The granular pre-emergent is safe once watered in. All products are EPA-registered and used according to label guidelines.
The pre-emergent must be activated by water to be effective. If you cannot water within the 72-hour window, water as soon as possible. The product will not breakdown for 20 days. You will not see effectiveness until it is watered in.
Subsurface drip irrigation alone is not sufficient to activate the pre-emergent. You would need to supplement with overhead watering (hose or sprinkler) or wait for adequate rainfall. We're happy to discuss your specific irrigation setup to determine if this service is right for you.
