i. purpose
Examines plant relationships to explain beneficial, neutral, and competitive interactions between species growing within shared environments — naming the mechanism behind every interaction. Covers companion planting, guilds, nurse plants, trap crops, beneficial and antagonistic relationships, pollinator support, root and nutrient interactions, and traditional companion-planting lineage — distinguishing research-backed relationships from traditional practices with limited study.
