About GardeningByZone
GardeningByZone provides free, zone-specific planting calendars for gardeners across the United States. Every garden is different: your USDA Plant Hardiness Zone determines which crops thrive in your area and when to plant them. Our tool uses your zip code to identify your zone, show last spring frost and first fall frost, and list 100 vegetables, herbs, and flowers with planting guides.
Whether you're growing tomatoes, basil, sunflowers, or kale, we provide three key dates: when to start seeds indoors, when to transplant outside, and when to direct sow in the garden. For 54 crops those dates come from state extension-service guides; for the other 46 they are estimates counted from your zone's last spring frost. Browse our complete plant guides, explore planting schedules by zone, or read our growing guides and tips for in-depth gardening advice.
