Gardening in Lithuania: climate, frost dates and crops by region
We worked out the season of 8 cities of Lithuania from ten years of weather: the frost-free season lasts from 165 days in Mažeikiai to 197 days in Klaipėda. The last spring frost comes first in Klaipėda (around 29 April) and last in Mažeikiai (around 9 May).
Climate zones of Lithuania
By the days between the last spring frost and the first autumn frost.
How the regions of Lithuania differ
Klaipėda is the wettest of these cities with 910 mm a year, Šiauliai the driest with 684 mm. In all 8 cities at least one month averages below 0 °C at night; the longest such winter is in Mažeikiai (December–March).
Which crops suit which part of Lithuania
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.
