Companion Planting Guide
Companion planting is a natural way to enhance garden health and productivity by pairing plants that benefit one another. A sustainable alternative to monocultures, it helps deter pests, attract beneficial pollinators, improve soil fertility, suppress weeds, and provide physical support or shade for neighbouring plants.
