Why these dates

Plant out after the last frost. Divide every second or third spring: the centre of a clump dies out and the plant declines noticeably in its fourth year if left alone. Deadheading extends the display by several weeks.

Hardy to -30C. Rots in a wet winter on heavy ground, which is the usual reason a healthy clump fails to reappear in spring.

Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Shasta daisies are timed from 8 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Ciudad Nezahualcoyotl.

Ciudad Nezahualcoyotl sits in zone 9b, which is milder than this crop wants, and a winter that never really arrives is its own problem. The dates below still describe the right time of year; the open question is survival rather than timing.

Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 1, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
