When to plant Robusta coffee in Bunyangabu
Western, Uganda
Known here as mmwanyi · kahawa
Robusta (Coffea canephora) is a hardy evergreen coffee tree of the warm lowlands — bigger, tougher and higher-yielding than highland Arabica, and far better at shrugging off leaf rust.

| When to plant (establish) | 10 Feb 2026 – 28 Oct 2026 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | 1.6–1.8 t/ha | about 2.8 t/ha |
| Bearing cycle | 270–330 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. | |

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 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Bunyangabu is close to normal, so these dates match the pattern the area usually follows.
Planting after 28 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Bunyangabu
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For robusta coffee in Bunyangabu, the lie of the land is the tightest of the three at 60%. 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.

| This season's rain | Rain close to usual — plan around about 1,303 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.3 °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. |
