How long does garlic take

Garlic takes about 8 to 9 months from planting to harvest, depending on your zone and variety. In most of the US, you plant in fall (October or November) and harvest the following summer (June or July). If you plant in spring, you can still get garlic, but the bulbs will be smaller. Here is the exact timeline and what to do now.

The Full Garlic Timeline

Garlic is a long-season crop. From planting to harvest, expect 240 to 270 days. The process breaks down like this:

• Planting: Fall, 4 to 6 weeks before the ground freezes. In zones 3-5, that is late September to October. Zones 6-8, October to November. Zones 9-10, November to December (use softneck varieties).
• Root growth: Fall, before winter dormancy. Garlic grows roots, not shoots, in cool soil.
• Winter dormancy: The bulb sits underground, cold-hardy. It needs a cold period (below 50°F) for 6 to 8 weeks to trigger bulb formation.
• Spring growth: As soil warms, leaves emerge. This happens in March or April, depending on zone.
• Bulb formation: When day length reaches 14 hours (usually May or June), the plant starts making bulbs.
• Harvest: When lower leaves turn brown, but 3 to 4 green leaves remain. That is typically 3 to 4 weeks after scapes appear (for hardneck) or in early summer. In zones 3-5, harvest is usually July; zones 6-8, June; zones 9-10, May.

Here is a table for quick reference by zone:

USDA Zone	Plant in Fall	Harvest in Summer
3-4	Late September to early October	Mid to late July
5-6	October to early November	Late June to July
7-8
November	June to early July
9-10	November to December	May to June

Varieties and Their Timing

Garlic comes in two main types: hardneck and softneck. Hardneck varieties (like ‘Music’, ‘German Red’, ‘Chesnok Red’) produce a flower stalk (scape) and have larger cloves. They need a cold winter, so they do best in zones 3-7. Softneck varieties (like ‘California Early’, ‘Inchelium Red’, ‘Silverwhite’) do not produce scapes and store longer. They are better for zones 8-10, but can grow in colder zones with mulch.

For fall planting, choose varieties suited to your zone. In cold zones, hardneck is reliable. In warm zones, softneck is essential because it does not require as much cold. If you plant in spring, use softneck varieties and expect smaller bulbs, about 1 to 2 inches in diameter, instead of 2 to 3 inches.

Planting Steps (Do This This Week)

If it is fall in your area, plant garlic now. Here is how:

1. Buy seed garlic: Purchase from a local nursery or online supplier. Expect to pay $10 to $15 per pound for seed garlic, which plants about 50 to 60 cloves. You need 1 pound per 50 feet of row.
2. Break the bulb into cloves: Keep the papery skin on. Choose the largest cloves; small ones yield small bulbs.
3. Prepare the soil: Garlic needs well-drained soil with pH 6.0 to 7.0. Add 2 inches of compost and a balanced fertilizer (10-10-10) at 1 pound per 50 square feet.
4. Plant cloves: Push each clove 2 to 3 inches deep, with the pointy end up. Space cloves 6 inches apart in rows 12 inches apart.
5. Mulch: Cover with 4 to 6 inches of straw or shredded leaves. This insulates the soil and prevents frost heaving.
6. Water: Give 1 inch of water after planting, then let rain handle it.

If you missed fall planting, you can plant in spring as soon as the soil thaws. Cloves will grow, but bulbs will be smaller. Plant 2 inches deep and keep the soil moist.

Caring for Garlic Through the Season

Garlic is low-maintenance, but a few tasks matter:

• Fertilize in spring: When shoots emerge, side-dress with nitrogen (blood meal or fish emulsion) at 1 pound per 50 feet. Repeat in May if leaves look pale.
• Water regularly: Garlic needs 1 inch per week from May until 2 weeks before harvest. Do not overwater; bulbs rot in soggy soil.
• Remove scapes: For hardneck, cut the curly flower stalk when it appears (usually June). This directs energy to the bulb. Use scissors or snap it off.
• Weed: Keep the bed weed-free, especially early on. Garlic does not compete well.

Harvesting and Curing

Harvest when the lower leaves are brown, but 3 to 4 green leaves remain. Dig up a bulb to check: the cloves should fill the skin and not be split. Use a garden fork to loosen soil, then pull bulbs by the stems. Do not leave them in the ground too long; they will split and not store well.

After harvest, cure garlic: hang bundles or lay them on a rack in a dry, shaded, well-ventilated spot for 2 to 4 weeks. The skin will paper up, and the neck will tighten. Then trim roots and cut stems to 1 inch, or braid softneck varieties.

FAQ

Can I plant garlic in spring? Yes, but expect smaller bulbs. Use softneck varieties and plant as early as the soil can be worked. You will harvest in late summer, about 4 to 5 months after planting.

How do I know when garlic is ready to harvest? Watch the leaves. When the bottom 3 to 4 leaves have turned brown, but the top 3 to 4 are still green, it is time. Dig a bulb to check: the cloves should be plump and the skin tight.

Why is my garlic not forming bulbs? The most common cause is planting too late or a mild winter. Garlic needs a cold period and longer days. If you live in a warm zone, plant softneck in late fall and mulch to keep soil cool.

Can I use grocery store garlic for planting? It is risky. Many store bulbs are treated to prevent sprouting, and they may carry diseases. Buy seed garlic from a reputable source for best results.

The Bottom Line

Garlic takes 8 to 9 months from fall planting to summer harvest. Plant in October or November, care for it through spring, and harvest in June or July. Choose hardneck for cold zones, softneck for warm zones. With minimal effort, you will have a full crop of bulbs that store for months. Start now, and you will be pulling fresh garlic by next summer.
