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
Garlic asks less of Alabama than people think.
Softneck territory, and here's why
Alabama sits in zone 8 across most of the state, which sounds like garlic country until you look at chill hours. Hardneck varieties need a long, unbroken stretch of cold to divide properly into a ring of full-size cloves, and a mild Alabama winter often shorts that requirement, leaving hardnecks with a handful of undersized cloves around a fat, useless stalk. Softnecks such as Inchelium Red and the various Silverskin strains do not carry that requirement. They form multiple layers of smaller cloves reliably in a shorter, gentler winter, and they store two to three months longer in the pantry than any hardneck, which matters if you grow more than a season's worth.
If you already prefer a hardneck for the kitchen, Spanish Roja still performs decently in the northern third of the state, where nights routinely sit below 40 degrees for six weeks or more each winter. Everywhere south of that line, plant softneck and skip the disappointment. Set individual cloves with the tip up, about 2 inches deep and 6 inches apart, and buy your planting stock from a garlic grower rather than a grocery bulb, since store garlic is frequently treated to stop sprouting and can carry disease into your bed.
Rain is the risk here, not cold
Utah gardeners fight drought; Alabama gardeners fight the opposite. Garlic sits in the ground through Alabama's wettest months, and that combination of standing moisture and mild warmth is exactly what downy mildew wants, the fungus that also dogs onions and every allium relative in a wet year. Build the row on a raised bed, 6 to 8 inches above grade, worked with 2 inches of compost, so water moves through instead of sitting against the cloves.
Mulch heavily once the cloves are in, 3 to 4 inches of straw, both to buffer the shallow roots through Alabama's freeze-thaw swings and to choke out winter weeds that garlic cannot outcompete on its own. Pull the mulch back an inch or two in early spring as green shoots emerge, so the crown is not sitting wet against a shoot base, which is exactly where downy mildew gets its first foothold.
Curing fights the humidity, not the calendar
The harvest signal is a leaf count, not a date: pull as soon as the plant is down to its last 3 to 5 green leaves, since each one still standing corresponds to one intact wrapper layer protecting the bulb. Wait for the whole plant to brown and you have usually waited too long; Alabama heat can push a fully mature bulb to split its own wrapper underground within days of that point.
Curing is the genuinely hard part here. With summer humidity routinely above 60 percent, open-air curing the way a desert garden manages it does not dry the bulbs fast enough, and mold moves in first. Move the harvest to a covered, moving-air spot instead, a carport or shed with a box fan running, and plan on 3 full weeks rather than 2. Check the batch weekly and pull any bulb that goes soft before it spreads to its neighbors.
In Alabama: watch for
The pests that find garlic here.
A middle-length season, about 228 frost-free days, means garlic overlaps onion thrips for a stretch each summer. Check plants every week or two and treat early.
Silvery streaks and curled leaf tips in hot spells.
Organic fix: Insecticidal soap or neem; hang sticky traps.
Seedlings wilt; white maggots in the bulb base.
Organic fix: Float a row cover over the row; rotate beds each year.
Pale patches with fuzzy gray growth in damp weather.
Organic fix: Space for airflow, water early in the day, spray neem.
White rot
Yellowing and dieback, then wilt; fluffy white mold at the bulb base and roots so rotted the plant lifts straight out.
Organic fix: No cure once it is in the soil. Plant clean stock, never follow onions with onions, and keep infested soil off tools and boots.
Your season math: Alabama gives garlic about 228 frost-free days, and it needs roughly 240 days to a first harvest. It's a one-planting crop, so time that single sowing well.
