Planting calendar by ZIP code
Find your planting calendar by ZIP code.
For ZIP 30301, GrowZone's planting calendar uses the Atlanta frost station, USDA zone 8a, a 226-day frost-free season, and crop rules to calculate start-indoors, transplant, direct-sow, harvest, and frost-watch dates.
Source: atlanta-hartsfield frost station, USDA zone 8a, last updated 2026-06-28. Verify locally before planting high-value crops because microclimates, current weather, and yard exposure can move the safe date.
Pick a crop and enter your ZIP to see when to start seeds indoors, transplant, direct-sow, and harvest, plus your last and first frost dates and frost-free day count. GrowZone maps your ZIP to a representative frost station and USDA hardiness zone, then applies crop-specific timing rules.
Supported crops: tomatoes, peppers, basil, carrots, lettuce, cucumbers, zucchini, cilantro, bush beans, spinach, radishes, kale, and watermelon.

Planting calendar FAQ
ZIP-code planting calendar questions.
How accurate is the planting calendar for my ZIP code?
GrowZone maps ZIP 30301 to the Atlanta frost station, USDA zone 8a, and crop-specific timing rules. It is more specific than a zone-only calendar, but it is still a planning estimate. Check your local forecast before planting tender crops.
Can I use GrowZone for early or late planting?
Use the ZIP calendar as the baseline, then adjust carefully for your yard, current weather, and how much frost risk you are willing to take. GrowZone shows frost-watch timing, but it does not replace a local forecast or an extension office recommendation.
What if I am moving to a new ZIP code?
Enter the new ZIP code and choose a crop. GrowZone recalculates the USDA zone, representative frost station, last and first frost estimates, and crop timing for that location.
Does GrowZone show what to plant each month?
Yes. ZIP month pages group supported crops into start-indoors, transplant, direct-sow, and wait-until-later sections. The lookup page also links into crop calendars, frost dates, hardiness-zone details, and what-to-plant-now pages.
