1. What is the Grass Seed Calculation?

The grass seed calculation determines how many pounds of seed you need to cover a specific area based on the coverage rate of the seed variety. Proper calculation ensures adequate coverage without wasting seed.

2. How Does the Calculator Work?

The calculator uses the simple formula:

\[ \text{Seed Needed (lbs)} = \frac{\text{Area (sq ft)}}{\text{Coverage Rate (sq ft/lb)}} \]

Where:

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

3. Importance of Proper Seeding

Details: Using the correct amount of seed ensures proper lawn establishment. Too little seed results in thin coverage, while too much wastes money and can lead to overcrowding.

4. Using the Calculator

Tips: Measure your lawn area accurately. Check the seed bag for coverage rates (typically 100-400 sq ft per lb). For new lawns, use the lower end of coverage rates.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure my lawn area?
A: Break irregular lawns into squares/rectangles, calculate each area (length × width), and sum them for total square footage.

Q2: Where do I find the coverage rate?
A: Check the seed packaging or supplier's specifications. Rates vary by grass type and seed quality.

Q3: Should I buy extra seed?
A: It's wise to purchase 10-15% extra to account for uneven distribution, washouts, or thin areas needing reseeding.

Q4: Does this work for overseeding?
A: For overseeding (adding seed to existing lawn), use half the normal seeding rate.

Q5: How does slope affect seeding?
A: Steep slopes may require up to 50% more seed due to potential washout, and erosion control mats are recommended.
