Best Time to Plant a Vegetable Garden by U.S. Region

Planting dates hinge on your last frost date, not the calendar. Use this regional framework as a starting point, then fine-tune with local data.

General Regional Windows (Cool-Season vs. Warm-Season Crops)

Key Factors Beyond Region

• Elevation: Higher = later frosts, shorter season.
• Coastal influence: Milder winters, cooler summers—extends both ends.
• Microclimate: South-facing walls, cold pockets, urban heat islands shift dates by weeks.
• Crop type: Peas, spinach, radishes tolerate frost; tomatoes, peppers, basil need 60°F+ soil.

Pro Strategies

• Start seeds indoors 6–8 weeks before transplant date.
• Use row covers or cold frames to gain 2–4 weeks early.
• Succession plant: sow quick crops (lettuce, radish) every 2–3 weeks.
• Fall garden: plant cool-season crops in mid-late summer for autumn harvest.

Get Local Precision

Check your county extension office or USDA Plant Hardiness Zone Map for exact frost dates. A $10 soil thermometer beats guesswork every time.
