Why Is My Garlic Sprouting in Storage?

You reach for a stored bulb and find the cloves have pushed out green shoots, or sprouted roots at the base. Sprouting in storage is a common frustration that shortens how long your garlic lasts, and it comes down to the conditions you are keeping it in. Garlic stays dormant only within a specific range, and certain storage spots actively trigger it to grow. Let me explain how to keep it dormant and good for months.

The wrong temperature triggers sprouting

This is the key point that surprises people: garlic sprouts fastest at cool, refrigerator-like temperatures, roughly 4–10°C. That is exactly the range that breaks its dormancy and tells it to grow — which is why garlic kept in the fridge, or in a cold damp shed, sprouts quickly. To keep garlic dormant for storage, store it warmer and dry: a cool, dry, airy room at around 10–18°C is ideal for eating garlic, keeping it dormant for months. So counterintuitively, the kitchen counter or a dry pantry keeps garlic far better than the fridge. (The cold-sprouting effect is useful only when you deliberately want to pre-sprout cloves for planting.)

Humidity matters too

Damp conditions encourage both sprouting and mould. Garlic needs to be stored dry, with good air circulation — never sealed in plastic bags, which trap moisture, and never in a humid spot. A mesh bag, net, basket, or braided and hung in an airy place keeps the air moving and the bulbs dry. High humidity, like a cold damp shed or the fridge, is a recipe for sprouting and rot; dry air keeps the bulbs firm and dormant.

Curing comes first

Garlic only stores well if it was properly cured after harvest. Freshly harvested garlic must be dried and cured for a few weeks in a warm, airy, shaded place until the skins are papery and the necks dry, which seals the bulbs for storage. Garlic that was not cured, or harvested too late with split skins, sprouts and spoils faster no matter how you store it. So good storage starts with good curing. Also, different varieties keep for different lengths — softneck garlic stores far longer than hardneck, which naturally sprouts sooner.

Keeping garlic dormant

To stop garlic sprouting in storage: cure it well after harvest, then store it cool but not cold (around 10–18°C), dry, and airy — on the counter, in a pantry, or hung in a mesh bag — never in the fridge or a damp place, and never sealed in plastic. Use longer-keeping softneck types if you want garlic to last into spring. And do not waste sprouted garlic — the cloves are still perfectly edible (just a touch milder), and a sprouted clove can be planted to grow a new plant or green garlic.
