Seasonal Gardening Guide for Every U.S. Region

Gardening in the United States is as diverse as its landscapes. From the arid deserts of the Southwest to the snowy terrain of the Northeast, each region has its unique set of climatic conditions that affect how, when, and what you can grow. This comprehensive Seasonal Gardening Guide will help you navigate planting, growing, and harvesting throughout the year in every major U.S. region. Whether you’re a novice or a seasoned gardener, understanding regional planting cycles is key to successful gardening.

Understanding Your USDA Hardiness Zone

Before diving into regional specifics, it’s crucial to identify your USDA Hardiness Zone. These zones, based on average annual minimum winter temperatures, help gardeners determine which plants are most likely to thrive in their area. You can find your zone by entering your zip code on the USDA website.

Seasonal Gardening Guide: Northeast Region

States Included

Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, and Pennsylvania.
