ROOT CELLAR

Cold Storage Field Guide

Store roots, squash, apples, and hardy foods with earth, shade, airflow, and humidity.

Core rule: Drainage and airflow first. Cold storage fails when it gets wet, sealed, stale, or too warm.

1 Storage Cutaway

earth cover insulated wall shelves / crates drain layer cool-air inlet warm-air outlet

Earth mass keeps temperature steadier. Airflow carries stale, damp air out while drainage keeps water away.

2 Pick the Right Site

Choose shade and drainage before convenience. A wet cellar spoils food fast.

3 Build the Storage

insulated shell drain base shelves / crates vent pipes

Keep food off the floor, separate crops, and give air a path in and out.
