France: Late August green bean sowing remains viable in specific regions

In certain regions of France, sowing green beans in late August remains a viable option for gardeners. According to Météo-France and INRAE recommendations, successful cultivation is possible where soil temperatures remain above 15°C and the autumn stays mild.

Specific areas where this practice is recommended include the Mediterranean surroundings (Occitanie, PACA, and Corsica), the Rhône Valley up to Montélimar, and the Atlantic coast stretching from the Basque Country to the Breton littoral. In Mediterranean regions, the soil retains summer heat, allowing the beans to complete their cycle before the first frost. On the Atlantic coast, oceanic influence and high humidity help mitigate early cold snaps.

A sowing period between August 20 and August 31 can lead to a harvest between late October and mid-November, provided there are approximately 60 frost-free days remaining.
