Spring Raised Bed Soil Checklist
A seasonal checklist for topping off raised beds, checking depth, and planning soil purchases.
Preset: annual top-off material
Formula: top-off volume = bed area × seasonal drop depth
Worked example: If a 4×8 bed dropped 2 inches over winter, top it off with about 5.33 ft³.
Adjust the live inputs above before copying the shopping list, printing the result, or buying material.
What to verify
Adding material without measuring the actual soil drop.
Using compost-only top-off every year without soil testing.
Confusing top-off material with mulch.
Page-specific notes
Check compaction before buying large amounts.
Refresh compost only as a planning estimate.
