4. Maintenance
Regular application of PGF Complete 16-4-8 will help maintain a healthy, vibrant lawn.
- Feeding Duration: The quick- and slow-release nitrogen provides extended feeding for up to 8 weeks. Plan your application schedule accordingly.

- Watering: Consistent watering is crucial for nutrient absorption and overall lawn health, especially after application.
5. Troubleshooting
If you encounter issues with your lawn after applying PGF Complete, consider the following:
- Uneven Greening: This may indicate uneven application. Ensure your spreader is calibrated correctly and you maintain a consistent walking speed with slight overlaps during application.
- Lack of Response: Verify that the product was watered in adequately after application. Insufficient watering can delay nutrient activation. Also, consider soil testing to identify any underlying deficiencies not addressed by this fertilizer.
- Yellowing Grass: While PGF Complete contains iron for deep greening, persistent yellowing might suggest other issues such as overwatering, disease, or extreme pH levels. Consult a local lawn care professional if symptoms persist.
