Grass Seed Formula:
From: | To: |
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.
The calculator uses the simple formula:
Where:
Explanation: The calculation divides your total area by how much area one pound of seed can cover to determine total pounds needed.
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.
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.
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.
