When to plant Robusta coffee in Funyula
Busia, 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.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 10 Feb 2027 – 11 Apr 2027 opens in 19 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.6 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. | |
| Work it takes | 122–255 days per hectare, by hand | |
| Rain meets its needs | 89% | |
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 22 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Funyula 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 11 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Funyula
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For robusta coffee in Funyula, 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 2025/26 season in Funyula
| When the rains are expected | February 2025 to January 2026 |
|---|---|
| Rain in a typical year | About 1,315 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 +1.0 °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 83% of this area. |
| 83% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 340 growing days · about 1,190 mm · February to January |
|---|---|
| 8% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 252 growing days · about 920 mm · August to January |
| 4% | 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 1,530 mm · January to January |

What it takes to grow robusta coffee in Funyula
| Planting material | About 1,350 plants per hectare |
|---|---|
| Nitrogen (N) | About 56 kg per hectare |
| Phosphate (P₂O₅) | About 11 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.
