Zucchini in St. Petersburg: soil, season and weather
In St. Petersburg frost, not soil, sets the date: the top 7 cm of soil averages 18 °C — the minimum on the zucchini card — already in the first week of January, before the last frost on 18 January, so planting waits only for the week after that frost. St. Petersburg has no autumn frost in the median year, so frost does not end the season.
