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

We worked out the season of 7 cities of Georgia from ten years of weather: the frost-free season lasts from 227 days in Tbilisi to 279 days in Zugdidi. The last spring frost comes first in Zugdidi (around 9 March) and last in Tbilisi (around 2 April).

How the regions of Georgia differ

The gap between the warmest month’s days and the coldest month’s nights is widest in Rustavi (35.7 °C) and smallest in Batumi (23.8 °C): the smaller it is, the milder both winter and summer. Batumi is the wettest of these cities with 2,589 mm a year, Rustavi the driest with 398 mm. The hottest summer days are in Rustavi (32.6 °C on average in the warmest month), the coolest in Batumi (26.3 °C). In 3 of the 7 cities at least one month averages below 0 °C at night; the longest such winter is in Gori (December–February).

Which crops suit which part of Georgia

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.
