Common questions about main crop plants
Does Companion Planting Ratio include mature plant size?
No. Companion Planting Ratio evaluates geometry; mature spread, airflow, access, and supports remain separate checks.
How does “A numeric ratio does not establish that two species benefit one another.” affect companion plants?
The formula cannot infer that condition from the other entries. Verify main crop plants before treating the result as a field target.
