Fertilization

Your lawn needs proper nutrition to stay thick and green in Seattle's climate, and timing matters more than most people think—because fertilizing when your grass can actually use those nutrients delivers better results than just following a generic national lawn care calendar. We apply organic or slow-release fertilizer in April when your lawn is actively growing and needs energy to thicken up before summer, which helps grass develop the density to naturally crowd out moss and weeds throughout King County properties. When fall rains return in September, we fertilize again to strengthen root systems before winter, and finish with a late-season application in November that keeps your lawn healthy through the wet months ahead—a three-application schedule that follows what actually works in western Washington's climate. Proper fertilization does more than make grass look greener: when lawns receive the right nutrients at the right times, they develop deep root systems that handle Seattle's wet winters and dry summers with less stress, and thick, well-fed turf naturally resists moss invasion, which is critical in our climate where thin, undernourished lawns can be overrun in just a few months. Our landscape maintenance services in Seattle use formulations matched to Pacific Northwest soil conditions and seasonal patterns, whether you prefer organic or conventional options, because we're not just feeding grass—we're building the foundation for a lawn that performs well year-round, reduces the need for moss treatments, limits weed pressure, and requires fewer interventions overall with the right care at the right moments.
