Watermelon in Ivanovo: soil, season and weather

In Ivanovo the soil, not frost, sets the date: the last frost is over around 3 May, but the top 7 cm of soil reaches 18 °C — the minimum on the watermelon card — only around 15 June, 43 days later. 118 days separate planting out (15 June) from the first autumn frost (11 October); the card's 59 days to the first harvest leave 59 for picking, so a start 8 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.
