Depth cheat sheet

The Depth Cheat Sheet is a one page printable reference covering the recommended depth for common landscaping situations, mulch beds and shrub borders, under trees, vegetable gardens, mulch paths, and drainage areas, alongside how far one cubic yard of material stretches at each depth. It is built to be printed and kept in a garage, glove box, or garden shed during a project, rather than read once on a screen.

What is on the sheet

Recommended depth ranges for each project type covered in the mulch depth guide, plus a compact coverage table showing square feet covered per cubic yard at 1, 2, 3, and 4 inches, the same figures used throughout this site's guides and by the calculator itself.

Looking for more than one sheet

For a project spanning several zones or materials, The Landscape Material Planner extends this same reference into a full 20 page planning document with coverage tables for all nine materials, a budget grid, and a delivery checklist.
