Gardening in Romania: climate, frost dates and crops by region

Climate zones of Romania

By the days between the last spring frost and the first autumn frost.

How the regions of Romania differ

Splitting the cities in two — north (Satu Mare, Baia Mare, Cluj-Napoca and Bacău) and south (Târgu Mureș, Arad, Pitești and Bucharest): the last spring frost comes about 10 days later in the north; the frost-free season is about 211 days in the north and 229 days in the south; the warmest month averages 27.5 °C by day in the north and 29.3 °C in the south.

The gap between the warmest month’s days and the coldest month’s nights is widest in Bucharest (34.1 °C) and smallest in Baia Mare (28.7 °C): the smaller it is, the milder both winter and summer. Baia Mare is the wettest of these cities with 1,116 mm a year, Bacău the driest with 562 mm. The hottest summer days are in Bucharest (30.5 °C on average in the warmest month), the coolest in Baia Mare (24.5 °C). In all 8 cities at least one month averages below 0 °C at night; the longest such winter is in Satu Mare (December–February).

Which crops suit which part of Romania

Season long enough: the days from planting to the first autumn frost cover the days to the first harvest on the plant card. 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.
