When to sow michaelmas daisies in São Paulo

Why these dates

Plant out in spring. Pinch the shoots back by a third in early summer to keep a 1.2m plant self-supporting rather than staked. Divide every two or three years, because clumps run outward and die out in the middle.

Hardy to -30C. Mildew in a dry summer is the usual complaint, not winter damage; keeping the roots moist prevents most of it.

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. Michaelmas daisies are timed with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for São Paulo.

São Paulo sits in zone 10b, 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.
