Why
Layout: Workable together; keep 2-3 feet and never follow one with the other in rotation.
- A real, documented or strongly plausible reason to keep these apart or plant with care — shared disease, allelopathy, competition, or resource mismatch.
- Companion planting tweaks the odds — spacing, rotation, and airflow still matter more than any pairing.
When this doesn't apply
- Small gardens with no disease history can often get away with it — the rating protects against the bad year, not the average one.
