Do I need weed control with fertilization?

How long does it take to see results?
Most customers notice greener color within 7–10 days, with improved thickness and health after a few weeks of consistent treatments.
Is fertilization safe for pets and kids?
Yes. Once the lawn is fully dry (usually 1–2 hours), it’s safe for pets and kids to return to the yard.
