Companion plants for both peppers and rosemary
Plants that are good neighbours of each. Biggest harvest gain first; each cell links to the evidence for that pair.
| Plant | With peppers | With rosemary |
|---|---|---|
| Carrot | 127% more harvest from the same spaceField trial, 1 study. Charts: not listed.Evidence for peppers and carrots | No trial foundNot tested. Charts: recommend.Evidence for rosemary and carrots |
Harvest from the same space compares a bed with both crops against the same area split into single-crop beds, counting the harvest of both crops (the land equivalent ratio in yield trials).
