Tomato in Yakutsk: soil, season and weather

In Yakutsk the soil, not frost, sets the date: the last frost is over around 20 May, but the top 7 cm of soil reaches 15 °C — the minimum on the tomato card — only around 16 June, 27 days later. 94 days separate planting out (16 June) from the first autumn frost (18 September); the card's 70 days to the first harvest leave 24 for picking, so a start 3 weeks late would still fit.

Each window starts on the Greenly calendar date and ends on the last day that still leaves the crop’s days to harvest (from its card) before the average first autumn frost, plus six weeks of picking for crops harvested over weeks (tomatoes, peppers, aubergines, cucumbers, courgettes, pumpkins, watermelons, beans) — our rule; earlier in the window is safer.
