Eggplant in Whitehorse: soil, season and weather

In Whitehorse the soil, not frost, sets the date: the last frost is over around 18 May, but the top 7 cm of soil reaches 18 °C — the minimum on the eggplant card — only around 9 July, 52 days later. Planting out on 9 July leaves 81 days to the first autumn frost on 28 September, only 11 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.
