Companion planting planner
Pick a crop and see the companion relationships our extension-backed plant records can support today. No folklore and no compatibility guesses.
Choose a plant
Build a better bed around one crop
Choose from the plants connected by a cited companion source. We leave gaps visible instead of filling them with garden folklore.
4 profiles currently carry a direct cited relationship. The picker also includes plants named by those records.

Check the growing basics
Check timing, spacing, light, and water before placing the pair in a real bed.
