1. What is Grass Seed Calculation?

The grass seed calculation determines the amount of seed needed to cover a specific area based on the coverage rate of the seed product. This ensures you buy the right amount of seed for your lawn project.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Area \) — The size of the area to be seeded (m²)
• \( Coverage\ rate \) — How much area 1kg of seed covers (m²/kg)

Explanation: The calculation divides your total area by the coverage rate to determine how many kilograms of seed you need.

3. Importance of Accurate Calculation

Details: Proper seed calculation prevents over-seeding (waste of money) or under-seeding (patchy lawn). It's especially important for large projects where seed costs can be significant.

4. Using the Calculator

Tips: Measure your area accurately in square meters. Check the coverage rate on your seed packaging as rates vary by seed type. Typical rates range from 15-30 m²/kg for UK grass seeds.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical coverage rate for UK grass seed?
A: Most UK grass seeds cover 15-30 m² per kg, but always check your specific product's coverage rate.

Q2: Should I buy extra seed?
A: It's wise to buy 10-20% extra to account for uneven distribution, birds, and other factors.

Q3: Does season affect seed calculation?
A: No, but autumn sowing typically requires less seed than spring sowing due to better growing conditions.

Q4: How do I measure irregularly shaped areas?
A: Break the area into rectangles, calculate each separately, then sum the results.

Q5: Does seed type affect coverage rate?
A: Yes, fine grasses cover more area than coarse grasses. Shade-tolerant mixes often have higher coverage rates.
