Planting
Knowing when to plant a fall garden in Alabama is the difference between a bumper crop and a sad, wilted disappointment—but don’t stress. With Alabama’s 7B-8A heat zones, you’ve got a 6-week window (August through mid-October) to plant cool-season veggies that’ll thrive until frost hits. Skip the guesswork and learn exactly when to start seeds, transplant seedlings, and prep your soil for maximum harvests before winter sets in.
Picture this: crisp greens, sweet carrots, and homegrown herbs fresh from your garden long after summer’s over. The key? Planting at the right time to avoid summer’s lingering heat while giving crops enough time to mature before Alabama’s first frost (usually mid-November).
Whether you’re a first-timer or a seasoned gardener, I’ll break down the exact deadlines, best crops for your zone, and pro tips to stretch your growing season—so you can enjoy a garden that keeps giving, even as the temperatures drop.
You’ll also discover how to beat Alabama’s tricky climate with strategies like succession planting and protective covers. No more second-guessing whether your broccoli will bolt or your spinach will freeze—just a foolproof plan tailored to your backyard.

Alabama fall planting deadlines by heat zone 7B-8A (with frost risk dates)
Alabama’s Heat Zones 7B-8A give you a 6-8 week window for fall planting—starting in late summer and ending before the first frost. Miss these deadlines, and your cool-season crops won’t mature before winter. Here’s your exact schedule, broken down by zone, with frost risk dates from the Alabama Extension.
In Zone 7B (northern Alabama), the average first frost hits around November 15, while Zone 8A (southern Alabama) typically sees frost by November 25. Plan accordingly—some areas like Huntsville may frost earlier, while Mobile stays warmer longer.
Your last planting window for most fall crops is 4-6 weeks before frost. For Zone 7B, that means early October for heat-sensitive plants like broccoli and kale, while Zone 8A can push planting to mid-October for slower growers.
Heat tolerance is your secret weapon. Crops like radishes and bush beans handle summer heat better than spinach or lettuce. Plant heat-lovers first, then transition to cooler-weather crops as temperatures drop.
Use this summary table to pinpoint your exact planting deadlines, frost dates, and ideal crops for your Alabama location.
🌱 Alabama Fall Planting Deadlines by Zone
| Zone | First Frost Date | Last Planting Window | Heat-Tolerant Crops | Cool-Weather Crops |
|---|---|---|---|---|
| 7B (North AL) | Nov 15 | Early Oct | Radishes, Bush Beans, Swiss Chard | Broccoli, Kale, Lettuce |
| 8A (South AL) | Nov 25 | Mid-Oct | Cucumbers, Peppers, Green Onions | Spinach, Carrots, Cauliflower |
⚠️ Note: Adjust dates 1-2 weeks earlier for high-altitude areas like Lookout Mountain.
For Zone 7B, aim to plant bush beans and radishes by September 15—they mature in 30-40 days and can handle summer heat. Follow with broccoli and kale by October 1 for a late harvest.
In Zone 8A, you’ve got more flexibility. Start cucumbers and green onions in late August, then transition to spinach and carrots by September 30. This staggered approach ensures a continuous harvest until frost.
Pro tip: Check the Alabama Agricultural Statistics Service for your county’s 30-year frost average. Some years, frost hits early—so always have row covers ready to protect tender crops like lettuce or cabbage.
Missed the deadline? Don’t panic. Succession planting lets you sow fast-growing crops like radishes or turnips every 2 weeks until October 15 in Zone 7B or October 31 in Zone 8A. These quick harvesters give you greens even if frost arrives early.

Best fall crops for Alabama gardens (ranked by yield and heat tolerance)
Alabama’s fall garden thrives when you pick the right crops—those that handle late-summer heat while still maturing before first frost. I’ve ranked the top 10 vegetables, herbs, and flowers by their ability to deliver high yields in Heat Zones 7B-8A, plus their heat tolerance and frost hardiness.
Start with quick-harvest varieties like bush beans and radishes (ready in 30-40 days) if you’re planting late. For longer-season crops, prioritize heat-tolerant lettuce and collard greens, which handle Alabama’s lingering warmth better than standard varieties.
Here’s my top list, with a focus on heat resistance and frost tolerance:
