When to plant Robusta coffee in Ngororero
Western Province, Rwanda
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.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 27 Jul 2026 – 5 Oct 2026 open now | 1 Jan 2027 – 31 Mar 2027 |
| Expected harvest | about 1.5 t/ha | same |
| Bearing cycle | 270–330 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. | |
| Work it takes | 122–255 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 25 Sep 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Ngororero 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 5 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Ngororero
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For robusta coffee in Ngororero, 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.
The 2026/27 season in Ngororero
| When the rains are expected | August 2026 to July 2027 |
|---|---|
| Rain in a typical year | About 1,122 mm |
| This season's rain | Leaning wet — January, February, 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. |
| What that supports | enough rain for a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 50% of this area. |
| 50% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 332 growing days · about 1,100 mm · August to July |
|---|---|
| 32% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 365 growing days · about 1,330 mm · January to December |
| 14% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 328 growing days · about 1,060 mm · August to July |
| 4% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 332 growing days · about 1,090 mm · August to July |

What it takes to grow robusta coffee in Ngororero
| Planting material | About 1,350 plants per hectare |
|---|---|
| Nitrogen (N) | About 52 kg per hectare |
| Phosphate (P₂O₅) | About 10 kg per hectare |

| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. A nitrogen top dressing — urea or AN — goes on once the crop is established. |

These are the nutrients a robusta coffee crop of that size carries off the field. What you actually apply depends on what your soil already holds — which is what a soil test, or the app's field records, tell you.
