Understanding the best time to plant vegetables is essential for successful gardening. Whether you’re a beginner or a seasoned green thumb, using your USDA Plant Hardiness Zone helps determine when and what to plant based on your region’s climate. This guide breaks it all down by zone so you can grow vegetables with confidence, no matter where you live in the U.S.
The USDA Hardiness Zones are defined by the average minimum winter temperature in a region. They range from Zone 1 (coldest) to Zone 13 (warmest). Each zone affects when it’s safe to start planting vegetables, especially for frost-sensitive plants like tomatoes, cucumbers, and peppers.
