| Expected harvest | about 1.1 t/ha | same |
| Harvest | From 17 Nov 2027 to 25 Feb 2028, depending on the planting date | |

| Work it takes | 85–175 days per hectare, by hand | |
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 Aug 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Bundibugyo 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 29 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Bundibugyo
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For roselle in Bundibugyo, the lie of the land is the tightest of the three at 76%. 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.
The 2026/27 season in Bundibugyo
| When the rains are expected | February 2026 to January 2027 |
|---|---|
| Rain in a typical year | About 1,003 mm |
| This season's rain | Leaning wet — January, February, October, November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| This season's heat | Hotter than usual — about +1.2 °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. |

|---|---|
| Phosphate (P₂O₅) | About 16 kg per hectare |
