When to plant Robusta coffee in South Mugirango
Kisii, Kenya
Known here as 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.

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 11 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for South Mugirango 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 21 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in South Mugirango
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For robusta coffee in South Mugirango, 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.
The 2026 season in South Mugirango
| When the rains are expected | December 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 1,454 mm |
| This season's rain | Leaning wet — 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 +0.7 °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 | 3 kinds of ground. The season below is the largest that farms — about 59% of this area. |
| 59% | 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 1,420 mm · December to December |

What it takes to grow robusta coffee in South Mugirango
| Planting material | About 1,350 plants per hectare |
|---|---|
| Nitrogen (N) | About 63 kg per hectare |

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.
