Harvest leeks when shafts have reached usable thickness — leeks don't have one clean 'ripe' day like a fruit, so harvest anytime after they're a usable size — 120-150 days from transplanting for most cultivars; some newer types are ready in about 90 days.

Ready when: shafts have reached usable thickness — leeks don't have one clean 'ripe' day like a fruit, so harvest anytime after they're a usable size. Loosen soil with a garden fork before pulling to avoid snapping the shaft.
Do this this week
- 1.Watch for the sign: shafts have reached usable thickness
- 2.Pick like this: loosen soil with a garden fork before pulling to avoid snapping the shaft

Why
On the calendar: 120-150 days from transplanting for most cultivars; some newer types are ready in about 90 days. Watch the plants, not the date — the leaf signal is the trigger.
Storage: refrigerate; leeks keep considerably longer than most alliums, especially if left in the garden into cool fall weather.
- Days-to-maturity figures are averages from trial conditions — your season, variety and weather move them, which is why the visual readiness sign is the deciding test.
When this doesn't apply
- If you planted earlier or later than the typical window, shift the estimated dates by the same amount.
