Meta Description:
Struggling with patchy grass? This scientifically-backed guide reveals how to fertilize lawns in CA, OR & WA—including grass-specific schedules, legal requirements, and 2024's top-rated products.

-
Soil pH Imbalance (Aim for 6.0-7.0)
-
Drought Stress (Use slow-release nitrogen to prevent burn)
-
Local Regulations (e.g., California’s [phosphorus restrictions][2])
