When to sow tickseeds in Arequipa

Why these dates

Plant out or sow direct after the last frost. Shear the plant back by half when flowering slows in midsummer for a second flush that lasts to autumn. Deadheading is what keeps it going, so a neglected plant simply stops.

Hardy to -25C, though the large-flowered forms often behave as biennials in a wet winter and are worth resowing. Needs good drainage.

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. Tickseeds 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 Arequipa.

Arequipa sits in zone 10a, 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.
