What is companion planting?

Companion planting refers to the strategy of planting different species together in a way that they can benefit one another, leading to improved growth, pest control, or enhanced flavors. This approach leverages the natural relationships between plants, such as providing shade, support, or attracting beneficial insects while repelling harmful pests. For instance, certain combinations can enhance nutrient uptake or help control diseases, making it a valuable technique in sustainable gardening and agriculture.

The other options describe practices that do not align with the principles of companion planting. Planting the same species together is a method more suited for monoculture, which does not capitalize on the synergistic benefits found in diverse plant pairings. Planting in straight rows does not consider plant interactions but may instead focus on organization and aesthetics. Lastly, planting in isolation as a pest control strategy misses the opportunity that various plants bring through mutualistic relationships, which can enhance the overall health and resilience of the ecosystem.
