Why
On the calendar: spring through the end of June. Watch the plants, not the date — the leaf signal is the trigger.
Storage: refrigerate stalks; freezes well chopped.
- 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.
