Against the frost risk in Baranovichi
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 Baranovichi.
Baranovichi sits in zone 5b, which is colder than this crop is rated for, so it will need winter protection or a container that can be moved under cover. The dates below still describe the right time of year; the open question is survival rather than timing.
The median frost-free season here is 172 days, against 150 to 210 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
