Companion planting strategies involve pairing different plants together in a way that benefits both. By strategically selecting plant combinations, you can improve growth, deter pests, and enhance flavor. For instance, planting basil next to tomatoes helps repel harmful insects, while encouraging healthy growth. Additionally, some plants, like beans, fix nitrogen in the soil, benefiting nearby crops like corn. These natural alliances promote a balanced ecosystem in your garden, reducing the need for chemical fertilizers and pesticides. Companion planting not only boosts plant health but also supports a more sustainable and productive garden.
