Mulch & Gravel Tips
- Mulch depth: 5-10 cm (2-4 inches) is ideal; 7.5 cm (3 inches) is most common
- Gravel for walkways: Use 5-7.5 cm (2-3 inches) for foot traffic, 10+ cm (4+ inches) for driveways
- Topsoil for gardens: 10-15 cm (4-6 inches) for new beds, 5 cm (2 inches) for top dressing
- Bulk vs bags: Bulk is cheaper for >3 cubic yards; bags are easier for small jobs
- Weight matters: 1 cubic yard of gravel weighs ~1,270 kg (~2,800 lbs); mulch ~180-360 kg (~400-800 lbs)
- Order 5-10% extra for uneven ground and settling
