Companion planting pair lookup

Can I plant potato next to raspberry?

Usually no. Potato and Raspberry are listed as an incompatible companion pair.

Keep apart

Usually no. Potato and Raspberry are listed as an incompatible companion pair. West Virginia University Extension lists raspberry as a crop not to plant next to potato.

If your garden is small, this does not mean the crops can never appear in the same yard. It means they should not be treated as a helpful pair: give them separate rows or bed sections, keep good airflow, and rotate families between seasons.

Source basis: West Virginia University Extension companion planting chart. The cautious verdict is limited to the cited incompatibility rather than a claim that the pair will always fail.

Spacing tip: Give this pair separate bed zones when practical, and avoid following one with the other in the same spot without rotation.
