CucurbitaceaeCan you plant peas and cucumbers together?
It depends. The sources disagree about peas and cucumbers. Results on harvest were mixed in a study, while garden charts recommend it.
Why it depends
Mixed results on harvest. In a study, results on harvest were mixed.
A machine‐based analysis of trade‐offs and synergies in pea‐cucumber intercropping systems (Ikram A · 2026 · Agronomy journal.)Garden charts recommend it. 1 garden chart entry recommends growing them together. It cites no source. Charts pass on gardening tradition; they are not tests.

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).
