When to Plant: Planting Dates by Crop and ZIP Code

When to plant depends on your first and last frost dates: each guide below gives planting dates for every USDA planting zone, major U.S. cities, and any ZIP code.

Plant in fall

GarlicPlant cloves from mid-September to late November, before the ground freezes.
TulipsPlant tulip bulbs from late September to mid-December, once the soil has cooled below 60°F; chill them in the refrigerator first where winters are mild.

Planting dates come from NOAA 1991–2020 weather-station frost dates and university extension planting rules: How We Calculate Frost and Planting Dates. Frost dates for any ZIP code: First and Last Frost Dates by ZipCode.
