Choose the bed location, access width, and whether roots can reach native soil.
Measure the project
Measure inside length, width, and fill depth; multiply by bed count.
Estimate the main materialMaterial checklist
- Frame materials
- Soil blend
- Compost if indicated
- Hardware and optional protection
Check quantities, specifications, and delivery with your supplier. This list is a planning prompt, not a construction design.
Quantities to price
- Soil fill: inside length × inside width × actual fill depth; repeat for each bed.
- Frame: price boards from the outside perimeter and chosen wall height.
- Bags: divide fill cubic feet by the actual bag volume and round up.
Where the plan can change: If the bed is open to the ground, roots may extend below the frame. A bed on pavement needs its own drainage and depth plan.
Work sequence
- Build and level the frame
- Check drainage
- Fill with measured material
- Water in and recheck settled depth
