Soil Calculator Guide

Getting the right amount of soil is crucial for successful gardening. Too little leaves plants struggling, while too much wastes money. Our calculator helps you get it just right.

Recommended Soil Depths

  • Raised Beds: 8-12 inches minimum (20-30 cm) | 12-18 inches ideal (30-45 cm)

  • Topdressing Lawn: 1/4 to 1/2 inch (0.6-1.3 cm)
  • Vegetable Gardens: 12-18 inches (30-45 cm)
  • Flower Beds: 6-12 inches (15-30 cm)

Choosing the Right Soil
