Emergence
Emergence occurs after the last spring frost when soil temperatures consistently reach 100C.
Flowering
Flowering is triggered by lengthening photoperiods, typically occurring about 90 days after emergence.
Harvest
Harvest of leaf stalks typically begins before flowering, about 30 days prior to the main flowering period, and can continue for 45 days.
Senescence
Senescence begins with the first autumn frost, leading to dormancy.
Timing is relative to your local season (temperate Northern Hemisphere).
