Companion planting is an age-old gardening technique that involves planting certain crops together to enhance growth, deter pests, and improve flavor. This method is especially valuable for gardeners who cultivate heirloom varieties, as it can help preserve the genetic diversity and vitality of these unique plants.
What Is Companion Planting?
Companion planting is the strategic placement of different plants in close proximity to benefit each other. It relies on natural interactions such as pest deterrence, pollination enhancement, and nutrient sharing. This practice can lead to healthier plants and higher yields without the need for chemical interventions.
