Tool

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.
