Zucchini in Posadas: soil, season and weather
In Posadas frost, not soil, sets the date: the top 7 cm of soil warms to 18 °C — the minimum on the zucchini card — around 19 July, 1 day after the last frost on 18 July, so planting waits only for the week after that frost. Posadas has no autumn frost in the median year, so frost does not end the season.
