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 9 Jan 2027. That is the point in the window where the rains are most reliably established.

This season's outlook for Idjwi leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.

Planting after 15 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
