1. What is the Grass Seed Calculator?

This calculator helps determine how much grass seed you need for your lawn project in the UK, based on the area size and the coverage rate of the seed product you're purchasing (typically from Amazon UK).

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• \( Area \) — Size of your lawn in square meters
• \( Coverage\ Rate \) — How much area 1kg of seed covers (m²/kg)

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

3. Importance of Accurate Calculation

Details: Calculating the right amount of grass seed ensures you don't under-seed (resulting in patchy growth) or over-seed (wasting money on excess seed).

4. Using the Calculator

Tips:

• Measure your lawn area accurately in square meters
• Check the coverage rate on your chosen seed product (typically 2-5 m²/kg for UK grass seeds)
• Consider buying 10-20% extra to account for uneven distribution or patch repairs

5. Frequently Asked Questions (FAQ)

Q1: What's a typical coverage rate for UK grass seed?
A: Most UK grass seeds cover 3-5 m² per kg for new lawns, or 6-10 m² per kg for overseeding.

Q2: How do I measure my lawn area?
A: For rectangular lawns: length × width. For irregular shapes, break into rectangles or use an online area calculator tool.

Q3: Should I use different rates for different seasons?
A: Yes, you may need to increase the seeding rate by 20-30% in autumn/winter compared to spring/summer.

Q4: Does seed type affect the coverage rate?
A: Yes, fine grasses like fescues typically have better coverage than coarser ryegrasses. Always check the product specifications.

Q5: Where can I find quality grass seed on Amazon UK?
A: Look for products with high ratings, UK-grown seeds, and appropriate grass mixes for your intended use (shade, hard-wearing, etc.).
