Companion planting is a time-tested gardening strategy where you pair certain plants together to enhance growth, deter pests, and improve overall yields. When it comes to companion flowers for vegetables, these vibrant blooms aren’t just for aesthetics—they play a crucial role in creating a balanced ecosystem in your garden. By attracting beneficial insects, repelling harmful pests, and even enriching the soil, the right flowers can transform your vegetable patch into a thriving, resilient space.
