Crop Rotation vs Companion Planting
Use plant-family rotation records, source evidence, pest pressure, cover crops, pollinator habitat, and bed maps before mixing companion planting claims into a crop plan.
What each planning idea controls
- Crop rotation
- Crop rotation uses plant-family history across seasons so same-family crops are not repeatedly assigned to the same bed when avoidable.
- Companion planting
- Companion planting places crops, herbs, flowers, or cover crops together for space sharing, pollinator support, habitat, or limited research-backed examples.
- Plant family
- Plant family is the first rotation check because related crops often share pest, disease, and nutrient-pressure patterns.
- Evidence label
- Evidence label separates extension guidance and research-supported examples from lower-certainty companion chart claims.
- Same-family repeat
- Same-family repeat warnings matter more than a companion match when the previous crop and the next crop are closely related.
Decision workflow
- Start with rotation
- Do not use companion lists as a substitute for rotating plant families; check family history, pest pressure, source evidence, and bed map constraints first.
- Use companions as support
- Use flowers, herbs, quick crops, and cover crops to improve habitat, timing, space use, or soil cover without treating them as guaranteed pest control.
- Label weak claims
- Avoid universal compatible/incompatible charts unless the claim has extension guidance, crop-specific research, or a practical site reason behind it.
- Map the bed
- Place crop families, cover crops, pollinator rows, paths, and harvest timing on a map before mixing plants in tight beds.
- Recheck each season
- Update the previous-family record after harvest so the next crop plan does not accidentally repeat the same family under a companion-planting label.
