When to plant common vegetables & herbs

When to plant 12 common garden vegetables and herbs — from frost-tender tomatoes, peppers, and basil to cold-hardy peas, spinach, and lettuce. Each crop's guide explains its frost tolerance, days to maturity, and how to time planting by counting from your local last spring frost, the standard method taught by U.S. Cooperative Extension services.

Crops

Sorted by frost tolerance — hardiest first. Timing depends on your local frost dates; open a crop for details.
Crop Category Frost tolerance Start indoors? Days to maturity
Pea cool-season legume Hardy direct-sow 55–70 days
Spinach cool-season green Hardy direct-sow 40–50 days
Broccoli cool-season brassica Half-hardy 6–8 wk before 55–75 days
Carrot cool-season root Half-hardy direct-sow 60–80 days
Lettuce cool-season green Half-hardy 4–6 wk before 45–60 days
Bush bean warm-season legume Tender direct-sow 50–60 days
Cucumber warm-season vine Tender 3–4 wk before 50–70 days
Summer squash / zucchini warm-season vine Tender direct-sow 45–60 days
Sweet corn warm-season grain Tender direct-sow 60–90 days
Tomato warm-season fruit Tender 6–8 wk before 60–80 days
Basil warm-season herb Very tender 4–6 wk before 30–45 days
Pepper warm-season fruit Very tender 8–10 wk before 60–90 days

How the timing works

The dates for each crop come from a simple, well-established method: count forward or back from your average last spring frost. Cold-hardy crops go out weeks before it; tender crops wait until after it; long-maturing crops are started indoors first. Because the anchor is your local frost date, the same crop is planted on very different calendar days in Minneapolis and Atlanta. Pick your location on the home planner for exact dates, and see the methodology for the offsets and sources.
