Vegetables and Herbs You Can Plant in July by Hardiness Zone

Gardening in July can be a bit tricky due to the summer heat, but with the right selection of vegetables and herbs, you can still enjoy a productive garden. Understanding your USDA hardiness zone is crucial to making informed planting decisions. This article will explore the best vegetables and herbs to plant in July for each hardiness zone, providing you with detailed guidance to ensure a bountiful harvest.

Understanding Hardiness Zones

The USDA Plant Hardiness Zone Map divides North America into 13 zones based on the average annual minimum winter temperature. These zones help gardeners determine which plants are most likely to thrive in their specific climate. Zones range from Zone 1 (coldest) to Zone 13 (warmest), with each zone representing a 10°F difference in the minimum temperature. By knowing your hardiness zone, you can choose plants that are well-suited to your area’s climate conditions.
