When to plant Onion in Baringo Central
Baringo, Kenya
Known here as kitunguu
Onion is a cool-season vegetable you grow for its bulb — the swollen base of the leaves — but across sub-Saharan Africa it is most often grown as an irrigated hot dry-season crop, and it stands real heat (up to about 42 °C) as long as the water never stops.

| When to plant | 25 Mar 2027 – 23 Jun 2027 opens in 25 weeks | 21 Jan 2026 – 1 Jan 2027 |

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 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Baringo Central is close to normal, so these dates match the pattern the area usually follows.
Planting after 23 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

For onion in Baringo Central, the lie of the land is the tightest of the three at 45%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.
