Alabama · zones 7b–9a
When to plant lettuce in Alabama.
Sow between Feb 15 to Apr 1 in a typical year, keyed to Alabama's median last frost around Mar 25. A second, fall sowing fits Aug 25 to Oct 24. Dates below are state medians; your ZIP code shifts them by days to weeks.
The 2026 windows
Lettuce dates for a typical Alabama season.
Direct sow
Feb 15 to Apr 1
Keyed to the ~Mar 25 last frost. Sow 0.25" deep, 6" apart.
Fall round
Aug 25 to Oct 24
Counted back from the ~Nov 8 first frost.
Harvest
~45 days later
~0.4 lb per plant over ~1 weeks.
Alabama spans more than one climate: Zone 8 is the most common zone, but the state runs 7b to 9a. That's why the planner works from your ZIP code's frost dates, not your zone: mountain and coastal gardens in the same state can be three weeks apart.
Alabama growing notes
Alabama gives lettuce two short windows, not one long one.
Why one planting never satisfies here
Lettuce bolts and turns bitter once soil and air run consistently warm, and Alabama's spring turns from cool to genuinely hot in a matter of weeks, not months. That narrow window is why succession sowing matters here: start a fresh short row every week or so through spring and again through fall, so something is always at a pickable stage instead of one batch racing to seed together. A single spring planting misses most of the usable season; succession sowing is not optional here, it is the whole strategy.
Spring is the shorter, riskier window: get a fast head-forming type going as early as conditions allow, expect roughly 45 days to a harvestable head, and accept that anything still in the ground once afternoons run consistently into the 80s will bolt regardless of variety. Treat spring lettuce as a bonus crop you pick fast, not a planting you baby along.
Fall is where Alabama lettuce actually thrives
The real payoff window is fall into early winter. Once the heat breaks, lettuce stops bolting and starts holding in the garden instead of racing to seed, and a light frost, anything short of a hard freeze, sweetens the leaves rather than damaging them. Gardeners in the southern half of the state, where winters barely dip below the mid-20s, can often keep cutting leaf lettuce under a simple row cover through most of the cool season.
Heat-tolerant types like Jericho and Muir buy you a few extra warm weeks on either end of the fall window, holding their shape and flavor longer than a standard butterhead or iceberg type, both of which struggle outright in Alabama's climate and are not worth the garden space here. Newham, a red romaine, is another solid pick for stretching the shoulder seasons.
Slugs love your mulch as much as your lettuce
Alabama's humidity keeps garden mulch damp for days after any rain, which is ideal lettuce growing weather and equally ideal slug and snail weather. The test is simple: check the underside of outer leaves at dusk with a flashlight, and if you find more than a couple of slugs per plant, thin the mulch layer near the crown and switch to shallow beer traps set flush with the soil, emptied every 2 to 3 days.
Aphids cluster on the undersides of new leaves in warm spells; a strong water spray from the hose knocks most colonies down before they need anything stronger. Cutworms are a seedling-stage problem only, cutting a stem clean at soil level overnight, so a cardboard collar pressed an inch into the soil around each transplant solves it for the couple of weeks it actually matters.
In Alabama: watch for
The pests that find lettuce here.
A middle-length season, about 228 frost-free days, means lettuce, leaf overlaps aphids for a stretch each summer. Check plants every week or two and treat early.
Clusters tucked into the heart of the head.
Organic fix: Rinse well; insecticidal soap on young plants.
Ragged holes and slime trails, worse after rain.
Organic fix: Iron-phosphate bait; a diatomaceous-earth ring; hand-pick at night.
Seedlings clipped off at the soil line overnight.
Organic fix: Collars around the stems; Bt or diatomaceous earth.
Pale yellow patches boxed in by the leaf veins, with white fuzz underneath.
Organic fix: Give plants room, let them dry between waterings, clear old leaves, and pick resistant varieties.
Your season math: Alabama gives lettuce about 228 frost-free days, and it needs roughly 45 days to a first harvest. That fits about 19 re-sown rounds across the season, so you can keep it coming instead of picking once.
