Grass Seed Calculation Formula:
From: | To: |
The grass seed calculation helps determine the amount of seed needed to cover a specific area based on the recommended seeding rate. This ensures proper coverage without wasting seed or leaving bare spots.
The calculator uses the following formula:
Where:
Explanation: The formula scales the standard seeding rate (given per 1000 sq ft) to your specific lawn area.
Details: Proper seed calculation ensures optimal grass growth, prevents overcrowding or sparse coverage, and helps budget for lawn projects.
Tips: Measure your lawn area accurately in square feet. Check the seed package for recommended rates, which typically range from 3-10 lbs per 1000 sq ft depending on grass type.
Q1: How do I measure my lawn area?
A: Break your lawn into simple geometric shapes, calculate each area, and sum them up. For irregular shapes, use online mapping tools or professional measurement services.
Q2: What's the typical seeding rate?
A: Rates vary by grass type: Kentucky Bluegrass (2-3 lbs), Tall Fescue (6-8 lbs), Perennial Ryegrass (5-7 lbs). Always check your specific seed's recommendation.
Q3: Should I buy extra seed?
A: It's wise to purchase 10-15% extra to account for uneven distribution, birds, and washout.
Q4: Does this work for overseeding?
A: For overseeding, use about half the normal rate since you're supplementing existing grass.
Q5: How does slope affect seeding?
A: Steep slopes may require higher rates or erosion control measures to prevent seed washout.
