- Nutrition profile: Look for balanced N-P-K numbers aligned with your lawn’s needs; many purely organic options emphasize nitrogen sources from natural inputs.
- Coverage and application: Match bag size to your lawn area; consider whether you need multiple applications per season for ongoing green-up.
- Safety and usability: Prioritize pet- and family-friendly formulas if kids and animals frequent the yard; check re-entry times after application.
- Soil health: Some products include humic acids, calcium, or beneficial microbes that support soil structure and drought tolerance.
