When to Plant Garlic (and Why Fall Beats Spring)
Mea Cara · September 15, 2026 · 3 min read
Garlic is close to the perfect crop: it goes in when the garden is winding down, occupies ground nobody is competing for, needs almost nothing all winter, and comes out in midsummer in time for something else. It also has one strict rule — plant it in fall.
The timing
Plant two to four weeks before your ground freezes hard, which in most cold-winter regions means somewhere between mid-October and late November. In mild-winter areas it stretches into December or January.
You're aiming for a specific outcome: enough time for the clove to grow roots, not enough for it to push much top growth before winter. A few inches of green before the cold arrives is fine. A lush plant in December is a plant that will suffer.
Garlic also needs a cold period — vernalization — to divide into a proper multi-clove bulb. Spring-planted garlic in a cold climate usually produces a single round instead. It's edible, it's just not what you wanted.
Which garlic to plant
- Hardneck — best in cold winters, fewer and larger cloves, easier to peel, and it gives you scapes in June. Stores perhaps four to six months.
- Softneck — better in mild climates, more cloves per bulb, stores far longer, and it's the type that braids.
- Elephant garlic — not garlic. It's a leek, milder, and grows enormous.
Buy seed garlic from a grower rather than planting supermarket bulbs, which are often treated to suppress sprouting and may carry disease. Once you're growing, save your best bulbs for replanting — the same principle as saving seed, and garlic adapts to a place remarkably fast.
Planting, in four lines
- Break bulbs into cloves the day you plant, not weeks before. Keep the papery skin on.
- Plant the biggest cloves — clove size largely determines bulb size. Cook the small ones.
- Pointed end up, 2 inches deep, 6 inches apart, in loose soil with compost worked in.
- Mulch with 4 inches of straw or shredded leaves after the ground chills. It moderates the freeze-thaw and suppresses spring weeds.
The two mistakes that produce small bulbs
Not watering in spring. Garlic does its bulking in the six weeks before harvest, and drought in May and June makes small bulbs no matter how well it was planted. Then stop watering two weeks before you lift, so it cures cleanly.
Leaving the scapes on. On hardneck types, cut the curling flower stalk when it loops. The plant redirects that energy into the bulb, and the scapes are one of the best things in the garden.
Harvest, and the note that makes next year better
Lift when about a third to a half of the leaves have browned — usually July. Every green leaf is a wrapper on the bulb, so waiting for all of them to die back leaves you with naked, poor-keeping heads. Cure it whole, out of sun, for two to three weeks.
Then write down which variety you planted, when it went in, when it came out, and how the bulbs sized up. Garlic runs on a nine-month clock, which is a long time to hold a detail like which hardneck did well — and it's the reason the garden calendar works better once it's built from your own records. GardenBinder keeps that plant-by-plant history for you, with the photos and the dates attached to the bed it happened in, so next October is a decision rather than a guess.
Everything else on the list is on the fall checklist — but garlic is the one worth not putting off.
