Use the result as a planning baseline
Companion claims are often overstated. This tool prioritizes shared light, water, soil and space rather than unsupported pest-control promises.
How to choose neighbors that can actually share a bed
Start with conditions, not folklore. Plants growing together should tolerate the same daily light, similar soil moisture and a compatible soil reaction. Their mature width and height also matter: a fast, spreading plant can crowd a slower neighbor even when both prefer the same care.
Use the shortlist as a comparison prompt, then open each plant profile before planting. Check mature size, airflow, root competition and harvest access. Keep aggressive spreaders such as mint in their own containers, and do not place moisture-loving herbs beside Mediterranean plants that need fast drainage.
What this finder does not claim
The result does not promise pest control, higher yield or protection from disease. Those outcomes depend on climate, variety, planting density, soil, beneficial insects and maintenance. Rotate crops where appropriate, inspect plants regularly and use local Extension guidance when a serious pest or disease appears.
