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 6 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Prefecture de Meknes is close to normal, so these dates match the pattern the area usually follows.
Planting after 26 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
