Companion planting, the practice of strategically pairing different plant species in close proximity, has been employed in horticulture for centuries. This technique not only enhances the visual appeal of gardens but also offers a myriad of practical advantages. By carefully selecting companion flowers for vegetables, gardeners can optimize plant growth, deter pests, attract beneficial insects, and improve overall garden health. Benefits of Companion Planting Increased Growth: Certain companion flowers release chemicals that promote vigorous growth in vegetable plants. For example, marigolds release alpha-terthienyl, a compound that stimulates root development in tomatoes and peppers. Pest Deterrence: Many companion flowers emit strong scents or contain compounds that repel common garden pests. Marigolds, for instance, deter nematodes, while nasturtiums repel aphids and whiteflies. Beneficial Insect Attraction: Companion flowers provide nectar and pollen for beneficial insects, such as ladybugs, bees, and parasitic wasps. These insects feed on pests or pollinate vegetable plants, enhancing their productivity. Improved Soil Health: Some companion flowers, such as legumes, fix nitrogen in the soil, making it more fertile. Others, like buckwheat, act as cover crops, suppressing weeds and improving soil structure. Choosing Companion Flowers
