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 and calculate precise planting dates for over 50 vegetables, herbs, and flowers.
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. All dates are calculated from your average last spring frost and first fall frost dates.
