USDA Zones 8a–8b–8bMost Mableton neighborhoods fall in USDA Zones 8a–8b–8b

Last spring frostTypical date: March 30

First fall frostTypical date: November 10

Cool season

Plant through winter

Broccoli, lettuce, peas, carrots, radishes and leafy greens perform best from fall through early spring.

Warm season

Use spring warmth

Plant warm-season vegetables after frost danger eases, protect soil moisture through summer heat, and return to brassicas, roots, peas and leafy greens for the fall garden.

Late summer

Restart the cool garden

Begin fall brassicas indoors and prepare beds for direct-sown roots and greens as temperatures moderate.

Planting Dates for Spring

Dates use Mableton valley-floor climate timing. Intense summer heat, dry air and nearby foothill elevation can change planting and harvest windows. Always check soil temperature and the 10-day forecast before planting.

How to Read This Calendar

Start indoors

Sow in trays under strong light. The window is timed so seedlings reach transplant size without becoming root-bound.

Transplant or plant

Harden seedlings off for about a week. Perennial crowns, sets and seed potatoes are included in this column.

Direct sow

Plant seed directly into prepared soil. Cool-season crops can begin before frost; heat-loving crops need warm soil.

Last planting

This is the practical end of the selected window—not a guarantee. Variety maturity and unusual weather can move it.

Keep soil working after harvest

Fall Cover Crop Planting Calendar

These windows are calculated from this city’s approximate first fall frost. Sow into an open bed after harvesting vegetables, then follow the selected crop’s product directions.

Let Soil Temperature Be the Final Check

Calendar dates start the conversation. A simple soil thermometer helps confirm that the seedbed is actually ready.

40–50°FPeas, spinach, radishes and other hardy crops

55–60°FBeans, corn and many moderately warm crops

65°F+Cucumbers, squash, melons, okra and other heat lovers
