What the frost dates mean for planting in Zone 7
The last spring frost is your green light for tender crops; the first fall frost is the deadline that ends the warm-season harvest. Long enough season for sweet potatoes and okra. Many gardeners grow in fall + winter using row covers for greens and brassicas.
Tender crops to sow after Zone 7's last frost
- When to plant tomatoes in Zone 7 — sow about 10 days after the last frost.
- When to plant peppers in Zone 7 — sow about 14 days after the last frost.
- When to plant basil in Zone 7 — sow about 7 days after the last frost.
- When to plant bush beans in Zone 7 — sow about 10 days after the last frost.
- When to plant cucumbers in Zone 7 — sow about 14 days after the last frost.
- When to plant summer squash in Zone 7 — sow about 14 days after the last frost.
Hardy crops (peas, lettuce, carrots) can go in two to five weeks before the last spring frost — they tolerate light cold that would kill the tender list above.
How to use these dates
- Anchor your spring planting to the last frost. Count backwards to start seeds indoors, and forward to time transplanting tender crops outside.
- Anchor your fall wind-down to the first frost. Stop sowing anything that cannot mature before that date, and start harvesting or covering tender crops two weeks ahead.
- Adjust for your microclimate. A south-facing wall, urban heat, or a frost pocket shifts these zone averages by one to three weeks — track your own first and last frosts each year.

Are these frost dates exact for my address?
No — these are zone-wide 30-year averages from NOAA Climate Data Online. Local microclimates (south-facing slopes, urban heat, frost pockets, lakeside warmth) can shift your real dates by one to three weeks. Use the Growli frost-date calculator with your ZIP code for a closer estimate.
