Can You Plant Onions, Grapes, and Apples Together?

Companion planting is a popular gardening technique that involves growing different plants together to maximize growth, improve flavor, and reduce pests. While onions, grapes, and apples are all common garden plants, planting them together requires careful consideration of their compatibility. This article will explore whether these plants can thrive together and provide practical tips for successful companion planting.
