Tomato in Murmansk: soil, season and weather

In Murmansk the soil, not frost, sets the date: the last frost is over around 24 May, but the top 7 cm of soil reaches 15 °C — the minimum on the tomato card — only around 16 July, 53 days later. Planting out on 16 July leaves 79 days to the first autumn frost on 3 October, only 9 more than the card's 70 days to the first harvest; an unheated greenhouse, three weeks earlier, would add 21.

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.
