When to Harvest Garlic (Count the Brown Leaves)

Garlic is ready when three or four lower leaves have browned and five or six are still green — usually July. How to read the plant and test before you dig.

Garlic gives you a fairly narrow window. Lift it two weeks early and the bulbs are small and will not cure; two weeks late and the wrappers have split and it will not store. Fortunately the plant tells you exactly where it is, if you know what to count.

Why leaves are the signal

Every leaf on a garlic plant connects to one wrapper layer around the bulb underground. As the season ends the plant sacrifices its lower leaves first, and each one that browns is a wrapper that has already broken down.

That is the whole logic of the harvest window. Lift with five or six green leaves and the bulb has five or six intact wrappers protecting it — that is what gives you months of storage. Leave it until only one or two are green and the bulb is left effectively naked in the soil, where it splits, picks up dirt between the cloves, and rots within weeks of coming out.

Check in the morning

Count the leaves early in the day. In hot afternoons garlic leaves wilt and discolour temporarily, which makes the plant look further along than it is.

Hardneck varieties generally come out one to two weeks before softnecks in the same bed, so do not assume the whole patch is ready at once.

Dig one test bulb first

Before you lift the bed, sacrifice a single plant from the middle of it — not the edge, where growing conditions differ.

Loosen the soil with a fork and lift the bulb. You are looking for three things:

  1. Plump, defined cloves that fill the skin, with clear divisions you can feel through the wrapper.
  2. Wrappers still intact and closed over the whole bulb.
  3. A firm neck, not soft or hollow.

If the cloves are still fused into a single mass with no clear divisions, give it another week and test again. If the wrappers are already splitting, harvest everything immediately.

Never pull garlic out by the stem

The stem separates from the bulb far more easily than you expect, especially in dry soil — and a bulb without its stem cannot cure. Always loosen with a fork several inches away from the plant first, then lift by hand from underneath.

Straight after lifting

Do not wash the bulbs, and do not leave them lying in the sun — garlic scorches surprisingly fast and scorched cloves go soft.

Brush off the loose soil with your hand, leave roots and stems attached, and move the whole plants somewhere dry, shaded, and airy to cure for two to four weeks. Once the necks are papery all the way through, trim and store them somewhere dark at 55–65°F.

The full cycle from planting to storage is covered in our complete guide to growing garlic.

Common questions

What month is garlic ready?

July in most of the US. Zones 8–10 harvest in May or June, zones 3–4 in late July or August. The month is a guide — the brown-leaf count is the actual signal.

What happens if I harvest garlic too late?

The papery wrappers split open and the cloves separate in the ground. Split bulbs are perfectly edible but will not store — use them within a few weeks.

What happens if I harvest too early?

You get a small bulb with soft, incompletely formed wrappers that will not cure properly. If the cloves have not filled out, the bulb will shrivel in storage rather than keep.

Should I water garlic before harvesting?

No. Stop watering 2–3 weeks before you plan to lift. Dry soil at the end produces clean, intact wrappers; wet soil produces stained bulbs that are much more likely to rot in storage.

Can I harvest garlic after the leaves have all died?

You can still eat it, but it is past its best for storage. Once every leaf has browned, the wrappers have usually deteriorated and the bulb may have started to split.
