Yacon through the year
Against the frost risk in Tangier
Why these dates
Plant rhizomes after the last frost. Lift when the first frost blackens the tops, and store the crowns frost-free for replanting.
Top growth is killed at 0C. The tubers survive a light frost in the ground but not a freeze, so they are lifted promptly.
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. Yacon are timed with planting out 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Tangier.
Tangier sits in zone 11b, 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.
