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 4 Oct 2026. That is the point in the window where the rains are most reliably established.

This season's outlook for Igembe North 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 24 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

What it takes to grow common bean in Igembe North

Planting materialAbout 175,000 plants per hectare
Nitrogen (N)About 79 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag
Phosphate (P₂O₅)About 26 kg per hectare
Potash (K₂O)About 41 kg per hectare
In the shopsA basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. Skip the nitrogen top dressing; inoculated seed does that job.
