Rain-fed. These dates are worked out from each place's own rainfall, for a field watered by the season — with irrigation a window can open earlier, close later, or come round more than once a year. Check your own field under What grows, or get the Divisi app for a calendar dated to your farm.
If you only get one chance to plant, aim for around 29 Sep 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Bizerte is close to normal, so these dates match the pattern the area usually follows.
Planting after 8 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Bizerte
| When the rains are expected | September 2026 to May 2027 |
|---|---|

| This season's rain | Rain close to usual — plan around about 638 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.1 °C over the growing months. Heat makes the same rain do less, so a dry spell bites sooner: do not plant late, and shade or mulch what you can. |

| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 93% of this area. |
