1. What is the Native Grass Seed Calculator?

The Native Grass Seed Calculator helps determine the amount of seed needed for overseeding based on the area size and the coverage rate of the seed mix. It ensures you purchase the right amount of seed for your project.

2. How Does the Calculator Work?

The calculator uses a simple formula:

\[ Seed\ Required\ (lbs) = \frac{Area\ (sq\ ft)}{Coverage\ Rate\ (sq\ ft\ per\ lb)} \]

Where:

Explanation: The calculation divides your total area by how much area one pound of seed can cover to determine how many pounds you need.

3. Importance of Proper Seeding Rate

Details: Using the correct amount of seed ensures optimal coverage without wasting seed or money. Too little seed results in poor coverage, while too much can lead to overcrowding and wasted resources.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between overseeding and new seeding rates?
A: Overseeding typically uses half the seed of new seeding since you're supplementing existing grass.

Q2: How do I measure my lawn area?
A: For rectangular areas, multiply length × width. For irregular shapes, break into rectangles or use online mapping tools.

Q3: What if my seed has different coverage rates for different species?
A: Use the most conservative (smallest) coverage rate to ensure you have enough seed.

Q4: Should I buy extra seed?
A: It's recommended to purchase 10-20% extra to account for spillage, uneven distribution, and patch repairs.

Q5: How does slope affect seeding rate?
A: Steep slopes may require slightly higher rates (10-20% more) as seed can wash away before establishing.
