Master Gardening Tools FAQ

What waste percentage should I use for materials?

For standard soil and mulch, add 5–10% for settling. For hardscaping (pavers, tiles), use 7–10% for simple layouts and 12–15% for complex diagonal or herringbone patterns.

How do I measure irregular garden beds?

Break irregular shapes down into simple squares, rectangles, and triangles. Calculate the area for each segment using our tools, then add the totals together.

How many bags of soil/mulch equal 1 cubic meter (m³)?

A standard 40-liter bag equals 0.04 m³. Therefore, you need exactly 25 bags of 40L soil or mulch to make up 1 cubic meter.

How do I prevent irrigation water runoff?

Use the "cycle-and-soak" method. Instead of watering for 30 minutes straight, split the run-time into three 10-minute cycles with 30-minute rest intervals to allow absorption.
