Companion planting planner
Pick a crop and build a practical bed plan. Confirmed companion records stay separate from condition-based suggestions, so the answer stays useful without pretending the data is fuller than it is.
Choose a plant
Build a better bed around one crop
Confirmed companion links come from cited plant entries. The bed-fit list uses sun, water, spacing, and category data so it stays practical when companion research is thin.
Current cited companion coverage: 4 of 553 plant profiles. This tool favors transparency over filling gaps with folklore.
