1. What is Overseeding?

Overseeding is the process of planting new grass seed directly into existing turf without tearing up the turf or soil. It helps improve turf density, enhance color, and introduce improved grass varieties.

2. How Does the Calculator Work?

The calculator uses this simple formula:

Where:

• 43,560 — Square feet in one acre
• Coverage Rate — The area one pound of seed will cover (varies by grass type)

3. Importance of Proper Seeding Rates

Details: Using the correct amount of seed ensures optimal turf establishment. Too little seed results in thin turf, while too much leads to competition and wasted resources.

4. Using the Calculator

Tips: Enter the coverage rate (found on your seed package) in square feet per pound. Typical coverage rates range from 100-300 sq ft per lb depending on grass type.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical coverage rate for common grasses?
A: Kentucky Bluegrass: ~100 sq ft/lb, Tall Fescue: ~200 sq ft/lb, Perennial Ryegrass: ~250 sq ft/lb

Q2: Should I use more seed for overseeding than new lawns?
A: Typically 50-75% of new lawn rates, as you're supplementing existing turf rather than starting from bare soil.

Q3: When is the best time to overseed?
A: Cool-season grasses: early fall; Warm-season grasses: late spring to early summer.

Q4: How do I prepare my lawn for overseeding?
A: Mow short, rake to remove debris, aerate if soil is compacted, then spread seed evenly.

Q5: Should I fertilize when overseeding?
A: Use a starter fertilizer to promote germination, but avoid weed-and-feed products that may inhibit new grass growth.
