Long white Asian radish doubling as a "biodriller" cover crop. Roots punch through compacted subsoil up to 60 cm; winter-kills leaving channels for water and root infiltration.
Hardiness ratings
| System | Rating | Temperature range | How to read it |
|---|---|---|---|
| USDA hardiness zone | Zone 2–10 | −45.6 °C to 4.4 °C | Zones where it can be grown as an annual — not a frost-tolerance rating |
| RHS hardiness rating | H7 | down to −20 °C | Plant needs at least this level of cold tolerance |
| Canadian plant hardiness zone | Zone 2–9 | −40 °C and warmer | Zones where it can be grown as an annual — not a frost-tolerance rating |
| Australian (ANBG) zone | Zone 1–6 | −15 °C to 15 °C | Zones where it can be grown as an annual — not a frost-tolerance rating |
As a tender annual, Daikon radish (Tillage radish) doesn't overwinter — the zone range shows where the growing season supports it. See the RHS rating for its actual cold tolerance.
Growing notes
- Roots reach up to 60 cm — opening channels in compacted soil that benefit the following crop's root system
- Winter-kills at around -7 °C, leaving in-place mulch and root channels — a feature for no-dig systems
- Brassica family — same rotation cautions as mustard for following brassica food crops
