Companion planting is an effective gardening technique that involves planting different crops close together to enhance growth, deter pests, and improve flavor. In Zone 3, where the growing season is short and weather conditions can be challenging, selecting the right companions for greens and brassicas is crucial for a successful garden.

Understanding Zone 3 Gardening Challenges
