1. What is Bark Mulch?

Bark mulch is a natural material made from shredded tree bark, commonly used in UK gardens for weed suppression, moisture retention, and improving soil quality. It's available in various types including pine, hardwood, and decorative bark.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Area \) — The surface area to be covered in square meters
• \( Depth \) — The desired depth of mulch in meters

Explanation: The formula calculates the volume of mulch needed by multiplying the area by the depth and converting to cubic meters.

3. Importance of Accurate Calculation

Details: Calculating the correct amount of bark mulch ensures you purchase the right quantity, avoiding waste or shortage. Proper depth (typically 5-10cm) is crucial for effective weed suppression and moisture retention.

4. Using the Calculator

Tips: Measure your garden area accurately in square meters. For depth, typical recommendations are 5-10cm (0.05-0.1m) for most applications. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How much area does 1m³ of bark mulch cover?
A: At 5cm depth, 1m³ covers approximately 20m². At 10cm depth, it covers about 10m².

Q2: What's the difference between bark mulch and wood chips?
A: Bark mulch is made from tree bark only, while wood chips include both bark and wood. Bark mulch decomposes slower and is better for weed suppression.

Q3: How often should I replace bark mulch?
A: Typically every 1-2 years as it decomposes and loses effectiveness.

Q4: Can I use bark mulch around all plants?
A: Most plants benefit, but avoid piling against tree trunks or plant stems to prevent rot.

Q5: Where can I buy bark mulch in the UK?
A: Available at garden centers, DIY stores, and online suppliers, often sold in bulk bags or loose by the cubic meter.
