What is companion planting?

Companion planting refers to the practice of growing different types of plants together in close proximity to enhance growth and provide mutual benefits. This technique can optimize space and promote healthier plants by utilizing various interactions among species, such as pest control, pollination, plant nutrient management, or providing shade and shelter. For instance, certain plants can deter pests that might harm neighboring plants, while others might attract beneficial insects that aid in pollination or natural pest control. This approach creates a more balanced garden ecosystem, promotes biodiversity, and can lead to increased yields without the need for chemical fertilizers or pesticides.

The other choices do not accurately capture the concept of companion planting. Planting the same crop in different seasons refers to crop rotation and does not involve the companion dynamic. Growing plants in isolation would hinder the benefits that can arise from inter-plant relationships. Lastly, focusing solely on native species limits the diverse interactions that can occur through companion planting, which often includes both native and non-native plants to maximize their complementary functions.
