1. What is Overseeding?

Overseeding is the process of spreading grass seed over an existing lawn to improve density, introduce new grass varieties, or repair damaged areas without starting from scratch.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• \( Area \) — The size of your lawn in square feet
• \( Coverage\ Rate \) — How many square feet one pound of seed will cover (varies by seed type)

Explanation: This calculation helps you determine exactly how much seed you need for your lawn area based on the recommended coverage rate for the specific grass seed you're using.

3. Importance of Proper Seeding Rates

Details: Using the correct amount of seed ensures optimal growth - too little seed results in thin growth, while too much leads to competition for resources and weak plants.

4. Using the Calculator

Tips:

• Measure your lawn accurately (length × width for rectangular areas)
• Check the coverage rate on your seed package (typically 200-400 sq ft/lb for overseeding)
• For irregularly shaped lawns, divide into sections and calculate each separately

5. Frequently Asked Questions (FAQ)

Q1: What's the typical coverage rate for overseeding?
A: Most grass seeds recommend 250-300 sq ft per pound for overseeding, but always check your specific product.

Q2: How does overseeding differ from new lawn seeding?
A: Overseeding uses about half the seed rate of establishing a new lawn since you're working with existing grass.

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

Q4: Should I prepare my lawn before overseeding?
A: Yes - mow short, rake to remove debris, and consider aerating for better seed-to-soil contact.

Q5: How long until I see results from overseeding?
A: Germination typically takes 5-14 days depending on grass type and conditions, with full results visible in 3-6 weeks.
