Tomato in Bariloche: soil, season and weather

In Bariloche frost, not soil, sets the date: the top 7 cm of soil warms to 15 °C — the minimum on the tomato card — around 31 December, 4 days after the last frost on 27 December, so planting waits only for the week after that frost. Only 8 days lie between planting out (3 January) and the first autumn frost (11 January), against the card's 70 days to the first harvest: even an unheated greenhouse, three weeks earlier, falls 41 days short without heat or a faster variety.
