Mulch & Soil Calculator

Estimate how much mulch or soil you need for your garden beds. Stop guessing and buying too many bags!

Enter the additional depth needed; account for mulch already present.

💡 Pro Tips

  • Ordering: Split irregular beds into rectangles and add their volumes. Bags are rounded up; allow for measurement uncertainty and supplier coverage.
  • Mulch Depth: Choose depth for the material and plants; keep mulch off trunks and stems.
  • Soil: Choose bed depth and soil composition for the plants and site; this tool calculates volume, not suitability.
