Useful Tips
- Follow the label: Never exceed labeled rates; water‑in as directed.
- Split applications: Staying ≤1.0 lb N per 1k ft² per pass helps avoid burn.
- Calibrate spreader: Use a catch‑test to validate your lbs/1k output.
- Mind the weather: Avoid heavy rain right after application to limit runoff.
- Soil test: Choose P and K based on test results—not guesswork.
- Sweep hardscape: Blow or sweep granules off sidewalks and driveways.
