Seasonal Application Schedule
Rates and timing are general guidelines. Adjust by 1–2 weeks based on your local frost dates and actual soil conditions. A soil test every 2–3 years gives the most accurate NPK targets.

Summary
Enter your grass type, lawn size, and region to get a full seasonal fertilizer schedule with NPK ratios, application rates, and dates.
How it works
- Select your grass type: cool-season (bluegrass, fescue, ryegrass) or warm-season (bermuda, zoysia, St. Augustine, centipede).
- Enter your lawn area in square feet.
- Choose your geographic region to adjust timing for local climate.
- The tool maps your selections to a proven seasonal schedule.
- Each entry shows the application window, NPK ratio, nitrogen rate, total fertilizer needed, and notes.
- Use the schedule as a guide — adjust by 1–2 weeks based on your actual first and last frost dates.
Use cases
- Plan the full season before buying fertilizer bags in spring.
- Avoid summer fertilizing cool-season grass during heat stress.
- Time fall applications to build root reserves before winter dormancy.
- Match NPK ratios to growth phase — high-N in spring, balanced in fall.
- Calculate total product needed for the year in one step.
- Teach new homeowners the "why" behind each fertilizer application.
- Compare schedules for different grass types if you are reseeding.
- Ensure you stop feeding warm-season grass before frost to prevent winterkill.
